Create stunning photorealistic images and videos from any CAD system, real life photo, or even a quick napkin sketch.
60 SECONDS. ZERO CONFIGURATION. STUNNING RESULTS.
PromeAI is a web-based AI design suite for turning sketches, photos, 3D model screenshots, and supported 3D model files into rendered architecture, interior, product, fashion, and creative visuals. Its toolset includes sketch rendering, region editing, consistency rendering, relighting, background tools, upscaling, and image-to-video generation for concept exploration and presentation polish.
PromeAI is closest to RENDERCAD when the starting asset is a sketch, floor plan, product photo, 3D model screenshot, or rough concept image that needs visual ideation, restyling, or quick presentation polish. It gives designers more prompt, style, reference-image, material-retention, and image-editing controls across architecture, interiors, products, and creative visuals. RENDERCAD is better when the job starts from an existing CAD or design viewport and the desired output is a render directly anchored to that view, with less setup than choosing PromeAI modes, templates, and prompt refinements.
PromeAI behaves more like a broad AI design workbench than a conventional renderer. Users can upload sketches, photos, 3D model screenshots, or supported model files, select scenes and styles, add prompts, use reference images, adjust perspective or lighting settings in some modes, and then refine with editing tools such as erase and replace, relight, upscaling, region rendering, consistency rendering, texture-preserving rendering, and image-to-video. That makes it useful for architects, interior designers, product teams, and marketing creatives who want many visual directions from loose inputs or stylized transformations. RENDERCAD fits the narrower CAD-to-render handoff. Instead of treating the design as a creative prompt canvas, RENDERCAD starts from a CAD viewport, product screenshot, architectural image, or other existing design visual and focuses on producing a polished render with minimal scene setup. Choose PromeAI when you want broader AI ideation, editing, style exploration, or video effects around an image. Choose RENDERCAD when you already have the model or design view and need a cleaner client, proposal, or marketing still without exporting geometry or rebuilding a render scene.
Screenshot the CAD viewport you already have, render in the browser, and download a client-ready still or video without exports, plugins, or GPU setup.

Get StartedCommon questions about RENDERCAD vs PromeAI
RENDERCAD excels at rapid client presentations. It delivers impressive photorealistic results in seconds, enabling real-time feedback sessions during design reviews.
For product marketing, client presentations, and concept work - yes. The Realistic engine is designed to improve lighting, materials, and presentation quality while keeping the original design recognizable.
Yes. Select the Realistic engine, set Condition to Clean, and type "Brushed Aluminum." The AI applies correct texture orientation to your geometry automatically.
RENDERCAD generates unique, non-repeating grain patterns that follow your object's form. Prompt "Oak Wood" and the engine handles scale, direction, and variation automatically.
RENDERCAD handles studio lighting automatically - select a Gradient or White background for a clean studio look. No manual light placement or HDRI setup needed.
Yes. Add "Golden Hour" to your prompt and the AI handles warm color temperature, long shadows, and soft light automatically.
Yes. The Seamless Loop option ensures the last frame matches the first for perfect looping - ready for social media, websites, and displays.
RENDERCAD creates videos from a single image in 1-2 minutes using AI. Upload a CAD screenshot, real photo, or hand drawing, select Image to Video, and choose a camera movement - no animation timeline required.
RENDERCAD still-image jobs usually complete in about 10 - 60 seconds. Competing AI tool speed depends on the selected model, prompt, queue, output type, and whether the job is image or video generation.
Yes. RENDERCAD runs independently as a browser app or overlay, so you continue modeling while renders process in the background.
RENDERCAD works from 2D images. Upload a CAD screenshot, real photo, or hand drawing - no file conversion, no exports, no compatibility issues.
Minimal. RENDERCAD uses natural language prompts anyone can use immediately - no technical sliders, shader graphs, or render settings to learn.
