ArchSynth is a web-based AI rendering platform for architects and interior designers that transforms sketches, images, and text into photorealistic renders and 3D models.
ArchSynth generates renders from sketches, moodboards, and text prompts - it's a generative tool for early-stage architectural ideation. RENDERCAD renders from CAD viewport screenshots - it preserves your actual design geometry, works with any CAD tool (SolidWorks, Revit, Fusion 360, SketchUp, and 824+ more), and includes video renders. If you have a finished CAD model and need a photorealistic render of it, RENDERCAD is the right tool. If you're ideating from sketches, ArchSynth fits that workflow.
ArchSynth is strong for concept-phase architecture: sketch to render, moodboard to visualization, text-to-image. Its 176K+ user base is primarily architects and interior designers in early design stages. However, it does not take CAD viewport screenshots as input - it generates from creative prompts and rough sketches. RENDERCAD works at the other end of the workflow: when you have a finished SolidWorks assembly, Revit building, Fusion 360 part, or SketchUp model and need a photorealistic render of what you actually built. RENDERCAD also protects your IP - only a screenshot is uploaded, your CAD files never leave your machine. ArchSynth requires uploading design imagery. RENDERCAD also includes AI video renders at base pricing - ArchSynth offers video but at higher credit cost.
Zero setup. No prompts required. Turn your product into a masterpiece before you can even think of a keyword.
RENDERCAD is powered by a proprietary ensemble of cutting-edge AI engines, fine-tuned to strictly maintain your design intent.

Side by side, feature by feature. See exactly where RENDERCAD's AI approach outperforms ArchSynth's traditional rendering pipeline.
In most software, a blank scene renders as darkness. You have to build the world before you can see it. In RENDERCAD, setup is zero. Snip your screen. The AI handles the lighting and materials automatically. Optional prompts are there if you need them. Otherwise, just click render.

Try NowCommon questions about RENDERCAD vs ArchSynth
With RENDERCAD, snip your screen, type "Carbon Fiber" in the prompt, and the AI retextures your image realistically in 10–30 seconds. No UV mapping or texture coordinates required.
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.
Prompt "Sunny Forest" or "Urban Street" and RENDERCAD generates a matching environment in 10–30 seconds. No scene file or environment map setup.
RENDERCAD creates videos from a single screenshot in 1–2 minutes using AI. Upload your image, select Image to Video, and choose a camera movement — no animation timeline required.
Yes. The Gentle Orbit camera setting generates subtle rotation from a single static image automatically.
Yes. The Seamless Loop option ensures the last frame matches the first for perfect looping — ready for social media, websites, and displays.
No. RENDERCAD runs on cloud GPUs, so you can render 4K images on a basic laptop or even a Chromebook. Your computer never slows down.
RENDERCAD produces photorealistic output in 10–30 seconds using AI. Traditional ArchSynth rendering typically takes minutes to hours depending on scene complexity.
Yes. RENDERCAD runs independently as a browser app or overlay, so you continue modeling while renders process in the background.
RENDERCAD works via screen capture. Snip your viewport — no file conversion, no exports, no compatibility issues. Works with any software.
Minimal. RENDERCAD uses natural language prompts anyone can use immediately — no technical sliders, shader graphs, or render settings to learn.
RENDERCAD starts at $20/month with credits that refresh monthly — predictable costs with no upfront investment or perpetual license fees.
For product marketing, client presentations, and concept work — yes. The Realistic engine produces photorealistic results trained on millions of professional photographs.
Yes. RENDERCAD understands materials semantically — it knows what brushed aluminum should look like without you defining roughness values, IOR, or shader parameters.
RENDERCAD excels at rapid client presentations. It delivers impressive photorealistic results in seconds, enabling real-time feedback sessions during design reviews.
