Plans and billing
- Can I buy more credits without upgrading?Yes. While your subscription is active you can buy a one-time top-up: 500 credits for $19, 2,000 for $69 or 10,000 for $299. You can also choose a custom amount from 100 to 50,000 credits. Top-ups are charged to the card saved on your account. Top-ups are not available if a payment has failed or your plan is paused or set to cancel.
- Can I get a refund if I am unhappy?Payments are generally not refunded. If you were charged by mistake, contact support within 24 hours of the charge and we will review it. Refunds are not given for unused time or for top-up packs. You can cancel your subscription at any time and keep access until the end of the period you paid for. Credits from a generation that failed are always returned to your balance automatically.
- Do unused credits roll over to next month?Yes. Unused credits stay in your balance when your plan renews. Each renewal adds your monthly credits on top of what you already have instead of resetting the balance. Credits you buy as top-ups also stay in your balance. This means you can save credits during a quiet month and use them in a busy one.
- How do credits work in Rendair AI?Credits pay for generations. Each action costs a set number of credits, depending on the model you choose and options like resolution or length. Text to image with Rendair v1 is free. Paid plans add credits every month, and unused credits stay in your balance when your plan renews. If a generation fails, the credits are returned automatically. You can also buy extra credits with a top-up.
- Understanding Rendair AI Plans and Pricing TiersRendair has four plans. Free costs $0 and includes 20 credits at signup plus unlimited text to image. Starter is $19 a month with 500 credits. Pro is $49 a month with 1,500 credits, priority queue and HD outputs. Studio Pro is $199 a month with 7,500 credits and room for a larger team. Paying annually costs ten months instead of twelve.
- What are the credit costs for each tool action?The cost depends on the model you pick. Text to image with Rendair v1 is free. Rendair v2 costs 1 credit at 1K and 2 at 2K. Upscaling costs 5 to 40 credits depending on the size. Nano Banana 2.1 costs 2 to 6, Nano Banana 2 3 to 6 and Flux 2 Pro 2 to 4, depending on resolution. GPT Image 2.5 costs 1 to 10 by quality. Video costs 38 to 190 credits, depending on length and resolution. 3D models cost 2 (Trellis) or 45 to 75 (Astra), and 3D scenes 10 to 100.
- API Access and Partnership RequestsAPI access is not included in any Rendair plan today. If you want to integrate Rendair into your own product, or you have a partnership idea, contact our team and tell us about your use case. We review each request individually and will get back to you.
- Can I add my VAT number or company details to invoices?Yes. When you subscribe or buy credits, the checkout page lets you add a VAT or tax ID together with your billing name and address, so they appear on your invoice. Enter the details before you pay. Payments are processed by Stripe, and you can also use a promotion code at checkout if you have one.
- Can I cancel my subscription at any time?Yes. You can cancel at any time from your billing settings and keep your paid access until the end of the period you already paid for. After that your account moves to the Free plan. Any credits left in your balance stay in your account. Payments already made are generally not refunded.
- Can I retry without losing credits?If a generation fails, the credits are returned to your balance automatically and you can try again at no cost. If the generation succeeds but you are not happy with the result, the credits are used, and a new attempt uses credits again. To save credits, try a cheaper draft or a lower resolution first, then run the final version once you like the direction.
- Can I use every app and feature on all plans?Yes. Every app and tool is available on every plan, including Free. What changes between plans is capacity, not access: your credits, how many images you get per run, how many generations run at once, and how many boards and people you can have. Priority queue and HD outputs come with Pro and Studio Pro, and Private Mode is not on Free.
- Can I use Rendair for free?Yes. The Free plan costs $0 and includes 20 credits when you sign up, unlimited text to image, 3 projects and 1 board. When you want more credits, or models and features that use credits, you can upgrade to a paid plan. Once you are subscribed, you can also buy extra credits with a top-up.
- Do subscriptions auto renew?Yes. Paid subscriptions renew automatically at the end of each billing period, monthly or yearly, and your saved card is charged. Your monthly credits are added when the plan renews. You can cancel at any time and keep your access until the end of the period you paid for, or pause your plan for up to 3 months.
- Does Rendair have an affiliate program?Yes. Rendair has an affiliate program for people who want to recommend Rendair to their audience. Approved partners get a personal referral link, and customers who sign up through it are tracked automatically. Apply at http://partners.dub.co/rendair, and we review each application.
- How do I renew my plan if payment failed?If a renewal payment fails, you will see a banner asking you to update your payment method. Generations and top-ups are paused until the payment goes through. Open your billing settings and update your card. Your payment is retried automatically, and once it succeeds your plan and monthly credits are restored.
- How to Pause Your Subscription Plan in Rendair AI?You can pause your paid plan for up to 3 months from your billing settings. The pause starts at the end of your current period and you are not charged for the next cycle. Your credits stay safe while paused. You can resume with one click at any time, or the plan resumes automatically at the end, and you get a reminder first.
- Is there a discount for yearly billing?Yes. Paying yearly costs ten times the monthly price, so you get two months free. Starter is $190 a year instead of $228, Pro is $490 instead of $588, and Studio Pro is $1,990 instead of $2,388. You can choose monthly or yearly billing when you subscribe.
- Is there a student plan?No. The Student plan is closed to new customers, so it cannot be selected anymore. Customers who already had it keep it. If you are a student, you can start on the Free plan with 20 credits and unlimited text to image, then move to a paid plan when you need more credits.
- What Happens to My Projects If I Cancel My Plan?Your projects are not deleted when you cancel. You keep your paid access until the end of the period you paid for. After that your account moves to the Free plan, and your renders, folders, boards and any credits you have left stay in your account. Boards above the Free limit are locked until you upgrade again.
- What payment methods do you accept?You can pay with a credit or debit card, Apple Pay, Google Pay and Link. Other local payment methods may also appear at checkout, depending on your country. The methods you see are shown when you pay. PayPal is not accepted. Payments are processed securely by Stripe, and your card details never touch Rendair.
Files and 3D models
- Can I use my 3D model from Revit?Yes. Rendair does not need a plugin. Export a view of your Revit model as a JPG or PNG and upload it to Image to Render. If you can export your model as a GLB, GLTF, OBJ or STL file, you can also use 3D Model to Render. Rendair keeps the shape and camera of your view and adds materials, light and context.
- Can I use my 3D model from Rhino?Yes. Export a view of your Rhino model as a JPG or PNG and upload it to Image to Render, or export the model as an OBJ or STL file and use 3D Model to Render. No plugin is needed. Rendair keeps the shape of your model and adds realistic materials, lighting and surroundings based on your prompt.
- Using Archicad models in RendairYes. Export a view of your Archicad model as a JPG or PNG and upload it to Image to Render. If you can export your model as a GLB, GLTF, OBJ or STL file, you can also use 3D Model to Render. No plugin is needed. Rendair keeps your design and adds materials, lighting and context.
- Using SketchUp models with RendairYes. Export a view of your SketchUp model as a JPG or PNG and upload it to Image to Render, or export the model as an OBJ or STL file and use 3D Model to Render. No plugin is needed. Rendair keeps your design and adds realistic materials, lighting and context from your prompt.
- What file formats can I upload?You can upload images as JPG, PNG or WebP, videos as MP4, WebM or MOV, and 3D models as GLB, GLTF, OBJ or STL. HEIC and AVIF images are not supported, so convert them to JPG or PNG first. PDFs can be added in the canvas editor. Each file type has its own maximum size, which is the same on every plan.
- Can I export a 3D model to SketchUp, Revit or Blender?Sometimes. Image to 3D Model and Floor Plan to 3D Model give you a GLB file you can download. GLB opens in Blender and many other 3D programs. If your software does not open GLB files, convert the file to another format such as OBJ first. Rendair does not export directly to SketchUp or Revit formats.
- Can You Use Rendair AI Images for Print and Large Screens?Yes, with the right steps. Use Upscale and Enhance to increase the resolution of your render by 2x, 4x, 6x or 8x, then download the PNG. For large prints, upscale your final version and check it at full size before printing. The size you need depends on the print size and the viewing distance.
- Do AI renderings have watermarks?Rendair does not add a watermark to your renders on any plan. Some of the AI models we use may add their own invisible marker or metadata that identifies an image as AI-generated. This comes from the model, not from Rendair, and it doesn't change how your image looks.
- Do You Need a 3D File or a Screenshot for Rendering?Either one works. If you have a 3D file in GLB, GLTF, OBJ or STL format, upload it to 3D Model to Render. If you only have a screenshot, image or sketch of your model, use Image to Render or Sketch to Render instead. A screenshot is faster and works with any software.
- How detailed should my sketch or image be before uploading?Your sketch does not need to be detailed. Clear lines, correct proportions and the main elements such as walls, openings and the roof are enough. Rendair adds materials, light and context based on your prompt. A short description of the materials and style helps most, especially for very rough sketches.
- What is the maximum upload size?The limit depends on the file type and is the same on every plan. Images can be up to 25 MB each, videos up to 200 MB and 3D models up to 100 MB. If your file is larger, compress it or export a lighter version before uploading. For images, JPG or WebP at a normal screen resolution is usually enough.
- What level of detail does my 3D model need?Your 3D model can be simple. A basic massing model with clear shapes, openings and correct proportions is enough. Rendair keeps the geometry and adds materials, detail, light and context based on your prompt. Fine details and textures are not required. Keep the file under 100 MB in GLB, GLTF, OBJ or STL format.
- What resolution are the exported images?The size depends on the model you choose. Many image models create 1K, 2K or 4K images, and you pick the size before you generate. Higher sizes cost more credits. You can also increase the resolution of any render afterwards with Upscale and Enhance, at 2x, 4x, 6x or 8x.
- What type of input gives the best results?The best results come from clear inputs: a sketch with clean lines, a screenshot of a 3D model, an elevation, a floor plan or a photo. Sharp images, good lighting and correct proportions help. Avoid very small, blurry or heavily compressed images. A short prompt describing materials, light and setting improves any result.
- Which file formats can I download?You download your results as they were generated, with no conversion. Images download as PNG and videos as MP4. 3D models download as GLB files, and 3D scenes as SPZ files with a WebP preview image. You can select several results in your assets and download them together as one zip file, up to 50 at a time.
- Why You Cannot Edit a PDF Directly and What to Do InsteadRendair works on images, so export the PDF page as a JPG or PNG and upload that image. You can then use tools such as Image to Render or Select and Modify on it. PDFs can also be added in the canvas editor. Use a high quality export so the drawing stays sharp.
Privacy and security
- Can I use the images I generated with Rendair AI commercially?Yes, on paid plans. Renders you create on Starter, Pro and Studio Pro can be used commercially, for example in client projects, presentations, marketing and listings. The Free plan is meant for trying Rendair and personal use. Rendair does not add a watermark to your renders on any plan. The full details are in our terms.
- Data Storage and Privacy in Rendair AIYour work is private to you and your team by default on paid plans, and stored in the United States. Rendair does not train its own AI models on your content, and AI providers process it to create your result. Payments are handled by Stripe. You can delete your images at any time, and support can delete your account and data.
- Does Rendair use my images to train AI models?Rendair does not use your images or prompts to train its own AI models. Our AI providers process your content only to create your result, and we choose providers whose terms for their business services do not allow training on it. Provider practices differ, and 3D scenes use a specialist provider with its own terms. Contact support if you need details.
- Are my projects visible to other users?On paid plans, your projects are private to you and your team by default. Other people can see a board only if you invite them or turn on its public link, and your renders appear in the community gallery only if you choose to publish them. On the Free plan, Rendair may feature renders on social media or the explore page.
- Can you sign a data processing agreement (DPA)?Yes. We can provide a data processing agreement (DPA) on request. Contact mailto:support@rendair.ai and tell us your company name and what you need. The DPA covers how we process personal data on your behalf and the companies we use to do it. Your data is stored in the United States.
- Commercial Rights and MLS Requirements for Generated ImagesOn a paid plan you can use your renders commercially, including in property marketing. MLS rules differ by region and each MLS sets its own requirements for edited or virtually staged images, and many ask you to disclose them. Check your MLS rules before you upload, and label images that show furniture or changes that do not exist.
- What does Private Mode mean in Rendair?On paid plans, your work is private by default, so there is nothing to switch on. Only you, your team and the people you invite to a board can see it, and you choose what to share. On the Free plan, Rendair may feature renders, for example on social media or the explore page, so upgrade if you need your work kept fully private.
- What is the Explore page and can other people see my renders?Explore is a community gallery inside Rendair where people share their generations. Nothing is shared automatically: a generation only appears if you choose Share to Explore. Shared items are reviewed before they go live, and you can unshare them at any time. On paid plans your renders are private by default. On the Free plan, Rendair may feature renders we like.
- Where is my data stored?Your data is stored in the United States. Your account data and generations are kept in our database, your files and images are stored with a global file storage and delivery network, and the app is hosted on a cloud platform. AI providers process your content to create your result, and payments are handled by Stripe.
Getting the result you want
- Creating Day and Night ScenesUse Change Time of Day on an existing render and choose morning, afternoon, evening or night. Rendair changes the light, the sky, the shadows and the glow from windows, while your design stays the same. Run it once for each time to show a project from day to night, and combine it with Change Weather for more mood.
- Generating Visuals from Floor Plans and ElevationsYes. Floor Plan to Render turns a 2D plan into a styled image, and Elevation to Render turns a facade drawing into a finished view. Upload a clear drawing, choose a style and describe the materials and mood. Rendair keeps the layout of your drawing. You can also turn a plan into an editable 3D model with Floor Plan to 3D Model.
- Can AI keep everything the same and change only one small thing?Yes, in most cases. Use an edit tool made for one change, such as Change Material, Change Time of Day, Change Season or Change Weather. To change a specific area, use Select and Modify and mark only that region. Check the result against the original, because you can try again or use Compare to see exactly what changed.
- Can I add context like surroundings or background buildings?Yes. Describe the surroundings in your prompt, such as neighboring buildings, the street, trees or a skyline. For a real site, upload a screenshot of the location or a reference image and set how strongly it should guide the result. If your image is too tight, Extend Image can add more of the scene around it.
- Can I combine a 3D model with a reference image?Yes. In the 3D Model to Render tool, upload your model and add one or more reference images for the mood, the materials or the setting. Then use Reference strength to decide how closely the render follows the reference, and Shape strength to keep the geometry of your model.
- Can I control realism versus conceptual style?Yes. Choose a style and describe the look in your prompt, from photorealistic to conceptual or illustrative. In the advanced settings, the Creativity slider sets how much freedom the model takes, and Style strength sets how firmly the style is applied. Lower values stay closer to your input, higher ones give more varied results.
- Can I correct people without affecting architecture?Yes. Use the Fix People tool. It finds the people in your render and corrects anatomy and unnatural poses, and you can choose details such as age range and gender. The building and the rest of the scene are not the target, but always compare with your original. It costs 3 credits.
- Can I create a 3D view from a 2D floorplan using AI?Yes. Upload your floor plan to Floor Plan to 3D Model, and Astra reads it and builds an editable 3D model with walls, openings, furniture and roof that you can download. Or use Floor Plan to Render to turn the plan into a styled image, such as an illustrated 3D view. The 3D model costs 45 to 75 credits.
- Can I create seasonal variations like summer or winter?Yes. Use the Change Season tool on an existing render and choose spring, summer, autumn or winter. The building stays the same while the vegetation, the light and the atmosphere change. You can run each season on the same image and compare them side by side.
- Can I generate early-stage concept visuals?Yes. Rendair is a fast way to turn early ideas into images. Start from a rough sketch, a massing view or just a text description, and try different moods and styles in minutes. Text to image with Rendair v1 costs no credits, so you can explore freely, then refine the direction you like.
- Can I generate multiple design variations quickly?Yes. Use Render Variation to create new versions of an image, or set the number of generations to make several at once. Pro and Studio Pro can generate up to 4 images per run, and Studio Pro can run up to 12 at the same time. Each image uses credits, so explore at a lower cost first.
- Can I remove objects or people from images?Yes. Use the Remove Object tool. Mark the object or person you want gone, and Rendair fills the space in a way that fits the surroundings. It works for cars, cables, signs, people and other clutter. For a bigger cleanup, do several small removals one after another.
- Can I render using a Google Maps screenshot?Yes. Take a screenshot of the site, upload it to Image to Render, and describe the building you want to see there. Rendair uses the screenshot as the setting. Choose a clear view with the angle you want, and check the map provider's terms if you plan to use the images commercially.
- Can I turn sketches into realistic renders?Yes. Upload your sketch to Sketch to Render, describe the materials, the light and the mood, and Rendair creates a realistic render that follows your lines. A clear sketch with strong outlines gives the best result. Use Shape strength to keep the drawing close, and try a few variations.
- Can I use reference images to guide the output?Yes. Add reference images in the advanced settings of the create tools to show Rendair the mood, the materials, the light or the setting you want. Then use Reference strength to set how closely the result follows them. A reference is best when it shows one clear idea.
- Can I visualize different furniture layouts quickly?Yes. Use Virtual Staging to furnish an empty room in a style you choose, such as Minimalist, Modern, Scandinavian or Industrial, and try a different style or layout with another run. You can also describe the layout you want, or use Select and Modify to change one piece of furniture at a time.
- Can I visualize unfinished or under construction buildings?Yes. Upload a photo of the site or of the building under construction, a sketch, a plan or a screenshot of your 3D model, and describe how it will look when it is finished. Rendair creates a finished render from it. It is a common way to show clients a building before it is built.
- Can Rendair match a specific architectural style?Yes. Name the style in your description, such as brutalist, Japanese minimalist or mid-century modern, choose a matching style in the tool, or add reference images of the look you want. Use Style strength to set how firmly it is applied.
- Controlling Camera Angles and Perspective in Rendair AIRendair follows the camera angle of the image you give it, so choose the view before you upload. For a 3D model, the render uses the camera position you set. You can also describe the perspective in your prompt. A Change Camera Angle tool is coming soon.
- Creating Architectural Visuals for Social Media FormatsChoose the aspect ratio before you generate. Options include square 1:1, portrait 4:5 and 2:3, landscape 5:4, 3:2 and 16:9, and vertical 9:16 for stories and reels, depending on the model. Use Extend Image to change the format of an existing render, and Image to Video to create a short clip for social media.
- Do materials from my 3D model affect the final result?They help, but you decide the final look. Rendair follows the shape of your 3D model, and textures in a GLB file give it hints. The materials in your render come mostly from your description, the style you choose and any reference image. Say the materials you want in your prompt, such as oak floor or white plaster.
- How accurate are materials like glass, concrete and wood?Rendair shows glass, concrete, wood and other materials convincingly, with reflections, texture and light, but the result is an AI interpretation, not a measured material. Name the material in your prompt, add a reference image of the exact finish, and use Change Material to adjust one surface. Always check important materials against your real samples.
- How do I add text or logos onto a building image?You can ask for signs or lettering in your prompt, or use Select and Modify to add them to an area of the image, but AI often spells words or draws logos imperfectly. For exact text or a real logo, add it afterwards in an image editor or presentation tool, where you control the result.
- How do I enhance an image without changing the design?Use Upscale and enhance. It makes your image larger and sharper without redesigning it. Choose 2x, 4x, 6x or 8x, which cost 5, 10, 20 and 40 credits. For a light polish at the same size, use Render Variation with a high Image strength so the result stays close to your original.
- How do I generate realistic interiors from empty spaces?Upload a photo or a render of the empty room to Virtual Staging, choose the room type and a style, and Rendair furnishes it in a realistic way. For a room that only exists as a sketch or a model, first make a render with Image to Render or Sketch to Render, then stage it. Try several styles to compare.
- How do I insert an object into an image?Use Select and Modify. Mark the area where the object should go and describe it, or add a reference image of the object. For furniture, Virtual Staging adds pieces to a room, and Populate Render adds people. Conversational Edit lets you ask for the change in words, such as add a bench by the entrance.
- How do I keep the same style across a project?Reuse the same ingredients for every image: the same style, the same model, the same reference images and the same wording for materials and light. Use Copy Inputs on a render you like to start from its exact settings.
- How Rendair AI handles scale and proportionsRendair follows the proportions of your input, so a good drawing or model gives a good result. Use Shape strength to keep the geometry close, and check important dimensions against your own plans. Rendair creates images, not measured drawings, so sizes are never guaranteed to be exact.
- How Rendair AI Interprets Lighting and ShadowsRendair reads the light in your image and your description, and creates shadows and reflections that fit. Say what you want, such as low evening sun from the left, and use Change Time of Day to adjust it. It is a visual result, not a light simulation, so it looks natural but is not a measured study of sun and shade.
- Prompting Guide and ExamplesDescribe the subject, the materials, the light and the mood in plain sentences, and be specific. For example: a modern timber house, warm evening light, large glass windows, landscaped garden. Add what to avoid in the negative prompt. If you are unsure, select the Prompt Assistant to improve your description, and change one thing at a time.
- What is the difference between editing and regenerating?Editing starts from an image you already have and changes part of it, so the rest stays close to what you had. Regenerating creates a new image from scratch, so everything can change. Edit when you like the image and want one change. Regenerate when you want to explore a different direction.
- When should I use image-to-image instead of text-to-image?Use an image as your starting point whenever you have one, such as a sketch, a plan, a photo or a view of your model. Rendair then keeps your design and adds the look. Use text to image when you have no input yet and want to explore ideas. Text to image with Rendair v1 costs no credits.
- Does the prompt assistant read my sketch?Yes. The Prompt Assistant looks at your uploaded image and up to three reference images, then improves your description. Select the Prompt Assistant button next to the prompt box, and choose Accept to use the suggestion or Again to get another. There are limits on how many requests you can make per minute and per day.
- For interior images, can I use a 3D model and set a camera?Yes. Upload your interior model to 3D Model to Render and frame the view you want. The render keeps the camera position of that view and the geometry of your model, and your description sets the style, the materials and the light. GLB is recommended for textured models.
- What is Render to Moodboard and which looks can I choose?Render to Moodboard turns a render into a presentation board for your concept. Pick a look before you generate: Default, Collage, Material Samples, Palette & Analysis, Editorial Brand or Story. Editorial Brand makes a polished brand-style board, and Story makes an early concept pitch board with keywords and references.
Getting started
- I used the old Rendair. Where are my projects?Your projects moved to the new Rendair. Sign in with the same email you used before and your account, team, renders, folders, subscription and credit balance are set up for you. Chat history does not carry over. Renders are copied in the background, so the newest appear first and older ones follow. The previous version of Rendair closed on 1 October 2026.
- Is there a plugin for SketchUp, Revit or Rhino?No plugin is needed. Rendair runs in your browser and works alongside SketchUp, Revit, Rhino and other design software. Export a view as an image and upload it, or upload a 3D file such as GLB, GLTF, OBJ or STL in the 3D Model to Render tool. Then download your results and keep working in your usual software.
- The Best Workflow for Concept to Final RenderA reliable workflow has five steps. Prepare a clear input, explore a direction at low cost, refine the chosen image with the edit tools, upscale the final version, then organize and share it. Working in this order saves credits, because you only spend on high quality once you know the direction is right.
- What is Rendair AI?Rendair is an AI visualization platform made for architects and designers. Upload a sketch, a floor plan, an elevation, a photo or a view of your 3D model, describe the mood you want, and get a finished render in minutes. You can then edit it, upscale it, turn it into a video or a 3D model, and share it with your team or client.
- Can I generate both interior and exterior renders?Yes. Rendair creates both exterior and interior renders. For exteriors, use Sketch to Render, Elevation to Render or a view of your 3D model. For interiors, upload a room view, and use Virtual Staging to furnish empty spaces. Then adjust the light, the materials and the mood with the edit tools.
- Can I use Rendair AI during live client meetings?Yes. You can generate and adjust visuals while you talk with a client, changing a material, the time of day or the mood in a few steps and showing the options on the spot. Start with cheaper draft resolution to move fast, then run the final version once the client picks a direction.
- Can I use Rendair AI for architectural competitions?Yes. Many designers use Rendair to explore ideas fast for a competition. You can turn sketches, elevations, floor plans or a simple 3D view into rendered images, try several moods and styles, and upscale the final images. It is best for exploring and presenting ideas quickly.
- Can I use Rendair AI for real estate marketing?Yes. Real estate teams use Rendair to show a property before it is built or furnished. You can turn plans, sketches or a 3D view into marketing images, furnish empty rooms with Virtual Staging, change the time of day or season, and create short videos from a still image.
- Can I use Rendair AI in an office environment?Yes. Rendair runs in the browser, so there is nothing to install on your office computers. Your team can work in one shared workspace with shared credits and boards, and owners and admins invite people by email. Pro and Studio Pro plans include room for team members, and you can add more seats.
- Can I use Rendair for client presentations?Yes. Many architects use Rendair to prepare client presentations. Create renders from your drawings and models, show alternatives on a board, share the board with your client as a viewer or with a public link, and download final images and videos for your slides. Upscale the images you present.
- Can I use Rendair on an iPad or phone?Yes. Rendair runs in your browser, so you can open it on a tablet or a phone with nothing to install. The layout adapts to smaller screens. For detailed work like editing a canvas or arranging a large board, a computer with a bigger screen is more comfortable.
- Create, Edit, and Upscale: Understanding the Core WorkflowsRendair has three core workflows. Create turns a sketch, plan, elevation, 3D view, photo or text prompt into a render. Edit changes an existing render, for example a material, the lighting, an object or a region of the image. Upscale makes the final image larger and sharper. Most projects move from Create to Edit to Upscale.
- Do I need AI experience to use Rendair?No. You do not need any AI or rendering experience. Upload a sketch, a plan or a 3D view, choose a tool, and describe what you want in plain words. The tools are made for architects, so you work with drawings and views you already have. You can also chat with the assistant, who helps you get started.
- Does Rendair AI replace tools like V-Ray or Enscape?Not exactly. V-Ray and Enscape are rendering engines that calculate light inside a fully built 3D scene. Rendair creates images with AI from a sketch, a plan or a view of your model. Many teams use both: their usual software for precise final images and Rendair for fast ideas, variations and moods.
- How is Rendair AI different from Photoshop generative fill?Photoshop generative fill adds or changes content inside a selected area of an image. Rendair is built for architecture. It creates complete renders from sketches, plans, elevations and 3D views, and its edit tools change materials, lighting, objects and regions while keeping the design. They work well together: create in Rendair, then retouch in Photoshop.
- How is Rendair AI different from traditional rendering software?Traditional rendering software builds an image by calculating light in a complete 3D scene, which gives precise control but takes setup time. Rendair uses AI to turn a sketch, a plan or a simple view into a finished image in minutes. It is faster for exploring ideas, and your existing software stays useful for exact final work.
- How often is Rendair AI updated?Rendair is improved continuously. New tools, models and improvements are added as they become ready, and you get them automatically the next time you open it, with nothing to install. Tools that are on the way are marked coming soon in the app. Your existing renders, boards and credits are not affected by updates.
- How Rendair AI Differs from Prompt-Only Image GeneratorsA prompt-only image generator makes an image from a text description alone, so the layout is different every time. Rendair works from your own input, such as a sketch, a plan, an elevation or a view of your 3D model. It keeps the geometry of your design, then adds materials, light and atmosphere from your description.
- Is Rendair AI a web app or do I need to install software?Rendair is a web app. You use it in your browser, so there is nothing to download or install. Sign in from any computer, tablet or phone, and your renders, boards and credits are all there. Your existing design software stays as it is, because you bring your work in as an image or a 3D file.
- Is Rendair suitable for professional client work?Yes. Architects and studios use Rendair for client work, from early concept images to presentation visuals. You get renders that follow your own drawings and models, edit tools to refine details, an upscaler for final images, and boards to share your work. Check every render against your design before you send it to a client.
- Language Support for Prompting and InterfaceRendair is available in seven languages: English, Spanish, Portuguese, French, German, Italian and Turkish. You can change the language of the interface in your settings. For your prompts, you can write in your own language, and the assistant will understand you.
- What is a board?A board is an open canvas where you collect and work on your renders. You can place images and videos on it, run tools on them, zoom around, and comment. You can also share a board with your team or a client, as a viewer or an editor. The number of boards depends on your plan.
- What types of architectural projects can I use Rendair for?Rendair works for almost any building or space you can draw, model or describe: houses, apartments, offices, shops, hotels, restaurants, interiors, facades and gardens. Start from a sketch, a plan, an elevation, a photo or a 3D view. The better your input, the closer the result will be to your design.
- Which AI models does Rendair use?Rendair gives you a choice of AI models, and the right one depends on the job. There are Rendair's own models for creating, editing and upscaling, other leading image models such as GPT Image 2.5, Nano Banana 2.1 and Flux 2 Pro, Kling V3 for video, and Astra, Trellis and Marble for 3D models and scenes. Each tool suggests a default.
- Which model should I choose?Start with the default model in each tool. It is chosen for that job. Switch when you want something different: a faster model for quick exploring, a more capable one for detailed edits or complex prompts. You can test the same input with two models and compare. Costs differ by model, so explore cheaply first.
- Which Nano Banana model should I use?Start with Nano Banana 2.1, the newest: fast, sharp up to 4K, and 2 to 6 credits. Use Nano Banana Pro for the highest quality and better spatial understanding (5 to 10 credits). Nano Banana and Nano Banana 2 Lite are quick and cheap for exploring ideas (2 credits).
- Who is Rendair designed for?Rendair is designed for architects and design professionals: architects, interior designers, visualizers, developers, real estate teams and students. It suits anyone who wants to turn sketches, plans or 3D views into images and show ideas fast, whether you work alone or in a studio.
- What is Astra?Astra is Rendair's 3D model tool. It reads a floor plan, a photo, a render, a sketch or an elevation and builds an editable 3D model with walls, openings, furniture, roof and site. You use it in the Image to 3D Model and Floor Plan to 3D Model tools, and you download the result as a GLB file.
- Which browsers work best?Rendair runs in your browser, so it works best in a current version of a major browser such as Chrome, Edge, Safari or Firefox. Keep your browser up to date. If something does not load or look right, refresh the page, try another browser, and contact support if it continues.
Problems and support
- I'm stuck on the security check when I sign inSelect Try again first. If it still fails, try another browser or network and turn off VPN and ad blockers for the page. You can also continue with Google, or select Email me a code: we send a one-time code to use together with your password. Still stuck? Write to mailto:support@rendair.ai.
- Do you provide tutorials or step-by-step guides?Yes. Many tools in Rendair have a short tutorial video that shows how to use them, and you can watch it inside the app while you work. These help pages also give step-by-step answers, and the assistant can walk you through a tool. Start with the best workflow guide for a full path from sketch to final render.
- How can I contact support if I need help?Email us at mailto:support@rendair.ai or use Contact support at the bottom of your settings, and we will get back to you. Tell us what you were trying to do, what you saw, and add a screenshot if you can. For more seats, custom credits or invoice billing, use Request a quote on the Enterprise plan instead.
- Understanding Generation Times and the Queue SystemMost images are ready quickly, but the time depends on the tool, the model and the resolution. When many people generate at once, requests wait in a queue and start in turn. Pro and Studio Pro use a priority queue. Your plan also sets how many generations can run at once, from 1 on Free to 12 on Studio Pro.
- What happens if a generation fails?If a generation fails, the credits are returned to your balance automatically, and you can try again at no cost. Refresh the page, check that your input file is supported, and try again. If it keeps failing, or your credits were used and you got no result, contact support with the time and the tool you used.
- What should I do if I cannot get the result I want?First check your input: a clear image gives a clearer result. Then make your description more specific, change one thing at a time, and try another model. Use the edit tools to fix one detail instead of starting over. Ask the assistant for help with your prompt, or contact support with your image and description.
- Why do images not load on my office or school network?Office and school networks sometimes block the domains Rendair uses to show images, or an ad blocker or a browser extension gets in the way. Try a private window or another network, such as your phone's hotspot. If that works, ask your IT team to allow http://rendair.ai and its related domains, or contact support for the list.
- Why does AI add unwanted default elements and how do I reduce it?AI fills in what your input and description leave open, so it can add people, cars, furniture or signs you did not ask for. To reduce this, describe exactly what you want, list what to avoid in the Negative prompt, use a cleaner input, and lower Creativity. Then use Remove Object to take out anything that is left.
- Why is the Generate button disabled or not working?The Generate button is usually disabled for a reason you can fix: a required image or description is missing, you do not have enough credits, the model needs a higher plan, you have reached the number of generations your plan can run at once, or a payment has failed. The message near the button tells you which one, and you can refresh the page if it does not respond.
Account and teams
- Can different team members have different permissions?Yes. When you invite someone to your team, you choose whether they join as a member or an admin, and only owners and admins can invite new people. On each board you can also share with a person as a viewer or an editor, and change that whenever you like.
- Can I collaborate with my team?Yes. Invite teammates by email from the Members page, and work together on boards where you can view, edit and comment on the same images. You choose what each person can do. Team size depends on your plan, and Pro and Studio Pro can add more people as extra seats.
- Can I Compare Multiple Variations Side by Side?Yes. Open any generation in the full-screen viewer and choose Compare to slide between the result and the image it started from. To look at several variations together, place them on the same board, where you can zoom out and see them all at once.
- Can I delete creations to free storage space?Yes. In Assets, select one or more images and choose Delete, and they move to the trash. If you only want an image out of a folder, use Remove from folder instead, which keeps it in Assets. Deleting a board also frees one of your plan's board slots.
- Can I delete my images and data permanently?Yes. You can delete images from Assets, and boards, folders and chats from their menus. Deleting your whole account from the account settings is coming soon. Until then, contact mailto:support@rendair.ai and we will delete your account and all your data. If you own a team with an active subscription, cancel it first.
- Can I invite a client to view a board?Yes. Open the board, select Share, and either invite your client by email as a viewer, or turn on the public link so anyone with it can view the board without an account. Email invites arrive with a one-time link that expires after 7 days.
- Can I organize projects into folders?Yes, with folders. Create a folder, then open any render and use Save to in the action bar to add it. Removing an image from a folder keeps it in Assets, and deleting a folder removes only the folder, never the images inside it. Your plan includes hundreds to thousands of folders.
- Can I reuse settings from a previous generation?Yes. Open a render you made and select Copy Inputs to load the same image, description and settings into the tool, then change only what you want. You can also choose an image from your previous creations as the input for a new generation. Your original render stays untouched.
- Can my team share credits?Yes. Credits belong to your team account, so everyone on the team draws from the same balance. Every extra seat you add brings 500 more credits a month to that shared balance. Paid plans include team members: Pro has 2 and Studio Pro has 5, and both can add extra seats. The Free and Starter plans are for one person.
- How do I add more seats to my plan?On Pro and Studio Pro you can add team members as extra seats for $19 per seat per month, or $190 per year. Each extra seat adds 500 credits a month. Pro can add up to 5 extra seats and Studio Pro up to 15. Free and Starter plans cannot add seats, so upgrade to Pro or Studio Pro first.
- How to update your password or email address?Open your account settings and choose Change password, then enter your current password and a new one. If you signed in with Google, you can add a password from the same page. If you have forgotten your password, use Forgot password on the sign-in page. Changing or resetting your password signs you out on your other devices. To change your email address, contact support.
- Is there a version history for my generations?Not as a separate feature, but nothing is overwritten. Every generation is saved in Assets as its own image, so earlier results stay available. Open any of them and select Details to see its prompt and settings, or Copy Inputs to start again from the same setup.
- What is a team in Rendair?A team is a shared Rendair workspace where several people work together under one subscription. Every team has owners, admins and members. Owners and admins can invite people, and you choose whether each person can view or edit a board. The number of team members included depends on your plan: 1 on Free and Starter, 2 on Pro and 5 on Studio Pro.
- Where to Find Your Chat Renders?Renders made in chat appear in the conversation, and they are also saved in Assets with everything else you create. To find an old one, open the conversation from your chat history, or search Assets by prompt.
- Can I duplicate a board as a starting point?Yes. On the Boards page, open a board's actions menu and choose Duplicate to get a copy you can build on. You can duplicate a folder the same way from its actions menu. The original stays exactly as it was, so you can try new directions safely.
- What happens when I remove someone from my team?They lose access to your team's workspace and can no longer use the team's credits, including in chat. Only owners and admins can remove people, from the Members page. Boards they shared with you stay with the team.
Video
- Can I control camera movement in videos?Yes, with your description. In Image to Video, write the movement you want, such as slowly zoom in, zoom out, orbit around the room or pan to the left. You can also add a start and an end image to control where the camera begins and ends. Short, simple movements usually work best.
- Can I export videos in different aspect ratios?The video takes the shape of your start image, so prepare that image in the format you want, such as vertical for stories or wide for presentations. If your image is outside the range the video model accepts, Rendair crops it to fit and tells you. Videos are downloaded as MP4 files.
- Can I generate videos with Rendair AI?Yes. Use Image to Video to turn a still render into a short video with smooth, cinematic camera movement. Upload an image, describe the movement you want, and choose the length, 5 or 10 seconds. You can also set a start and an end image. A video costs 38 to 190 credits, depending on length and resolution.
- How long does video generation take?A video takes longer than an image, because Rendair creates many frames. Longer videos take longer, and busy times can add waiting time. Pro and Studio Pro use a priority queue. You can leave the page while your video is created, and you will find it in Assets when it is ready.
- What to do if video generation errors or fails?If a video fails, your credits are returned to your balance automatically, and you can try again. Check that your image is a supported format and size, try a shorter video with a simpler movement, and refresh the page. If it keeps failing, contact support and include the time and the image.
- What Type of Motion Can Image-to-Video Generate?Image to Video can create smooth camera movements such as zooming in or out, panning, rotating and orbiting, and it can add natural motion to the scene. Short, single movements work best. Describe the motion in your prompt, or set a start and an end image to control where the movement goes.
