A client-side drawing recognition web app built with Next.js, Tailwind CSS and TensorFlow.js. Draw on the in-browser canvas and Lilith will try to guess your sketch in real time using QuickDraw model.

You can view the live application here:

• Real-time inference entirely in the browser (TensorFlow.js)
• Simple CNN-based sketch classifier (model loaded client-side)
• Interactive drawing canvas with undo/redo/erase
• Friendly UI and animated loading / dialogue components (Framer Motion)
• Lightweight — no server-side ML required

• Next.js
• TypeScript
• Tailwind CSS
• TensorFlow.js
• QuickDraw model
• Framer Motion
• Lucide icons

1. Install dependencies: npm install (or pnpm install / yarn)n)

2. Run dev server: npm run devv

3. Open http://localhost:3000 and draw on the canvas.

1. Build: npm run buildd

2. Start: npm run startt

• The Canvas component collects strokes and renders them to a 600×600 canvas.
• When you click "REVEAL!", the canvas pixel data is preprocessed and passed to a TensorFlow.js model (src/lib/tensorflow).
• The model returns class probabilities; the UI highlights the top prediction and shows a confidence bar.

• If the model fails to load, check console for fetch errors and ensure model files are in the expected public path.
• For canvas drawing issues, verify device pixel ratio & canvas size mapping in Canvas.tsx.tsx.

Issues and PRs are welcome.
