LogicLens is an Intent-to-App Engine. Draw arrows, boxes, and scribbles on a canvas. Our AI reads the topology, extracts the logic, and synthesizes a fully interactive React app — in seconds.

LogicLens Canvas

From napkin to app in 4 steps

No wizards. No complex dashboards. Just draw.

Draw

Sketch your UI on the canvas

Parse

AI extracts the logic graph

Generate

Code streams in real-time

Refine

Chat to iterate surgically

Built for engineers, not designers

Every feature serves the intent-to-app pipeline.

Draw Your Intent

Sketch on an infinite canvas or scan a paper napkin. Arrows become event handlers. Boxes become components.

AI Topology Extraction

Gemini 2.5 Flash reads your sketch and constructs a Semantic Logic Graph — nodes, edges, behaviors, and intent.

Live Code Synthesis

Gemini 2.5 Pro sees your image AND the logic graph. It generates React + Tailwind code that actually runs.

Conversational Refinement

Chat to refine. "Make it Cyberpunk." "Add a sort button." Surgical edits. Preview updates in under 2 seconds.

Draw your intent.

No sign-up. No configuration. Just open the canvas and start.
