What types of sketches work?

Gendo works with any visual input — pencil sketches, pen drawings, digital line art, grey 3D model exports, and even rough napkin drawings. The AI interprets spatial relationships, so as long as your sketch conveys room proportions and basic geometry, it will produce accurate results.

Gendo preserves the spatial geometry of your sketch. Room proportions, window positions, wall angles, and structural elements are maintained in the output render. You control style, materials, and lighting independently of the underlying geometry.

Can I control the style?

Yes. You can choose from preset styles, use text prompts to describe the desired aesthetic, or upload a reference image to define materials and mood. Style, materials, and lighting are all independently controllable.

Gendo offers a free plan with watermarked renders. No credit card required. Paid plans unlock unwatermarked outputs, more projects, and full commercial-use licensing.

What software can I use alongside Gendo?

Gendo accepts image inputs from any design tool — SketchUp, Revit, Rhino, ArchiCAD, Vectorworks, Blender, Procreate, and more. Any viewport export, screenshot, or scanned sketch works as a starting point.

How is Gendo different from generic AI image tools?

Generic AI image generators don't preserve architectural geometry or spatial proportions. Gendo is purpose-built for spatial design — it maintains room structure, supports material changes, and keeps all assets in a shared project canvas. Read the full comparison .

Can teams collaborate on sketch-to-render projects?

Yes. Gendo's canvas is a multiplayer workspace where team members can generate renders, leave notes, discuss variations, and build presentation packs together. It replaces fragmented workflows.

Is my design data secure?

On Studio and Enterprise plans, all prompts and outputs are treated as confidential IP. They are never used for model training. Gendo operates on GDPR-compliant EU data centres. Read more about data and control .

Frequently asked questions

Sketch to image AI tools allow designers, architects, and homeowners to transform hand-drawn sketches into photorealistic renders using artificial intelligence. Unlike generic AI image generators, Gendo's sketch to image AI is purpose-built for spatial design — preserving room proportions, architectural geometry, and structural accuracy. Whether you're working from a pencil sketch, a digital line drawing, or a rough massing model, AI-powered sketch-to-render workflows reduce visualisation time from hours to seconds, enabling faster design iteration and more confident client communication.
