# Install dependencies
make install

# Start development server
make dev

Open http://localhost:3000 in your browser.

make help      # Display all available commands
make install   # Install dependencies
make dev       # Start Next.js development server
make run       # Build and run production server
make clean     # Clean previous builds
make build     # Build for production (generates docs/)
make deploy    # Build and deploy to GitHub Pages

npm install
npm run dev

The project uses a Makefile for consistent builds and deployments, similar to www.hacktoolkit.com:

# Build the static site
make build

This will:

1. Clean previous builds
2. Install dependencies
3. Build Next.js static export to out/
4. Copy CNAME file to out/
5. Create .nojekyll file in out/

# Build and deploy in one command
make deploy

This will:

1. Run the build process
2. Move out/ directory to docs/
3. Commit the docs/ directory
4. Push to the master branch

GitHub Pages is configured to serve from the docs/ directory on the master branch.

• ⌘+Enter / Ctrl+Enter - Send message in chat
• ⌘+K / Ctrl+K - Toggle command palette
• Esc - Close modals

• ✅ Split-screen layout (Chat + Code Editor)
• ✅ Dark/Light theme toggle with localStorage persistence
• ✅ Syntax highlighting for multiple languages (Python, TypeScript, Rust, etc.)
• ✅ Keyboard-centric interaction
• ✅ Responsive design
• ✅ Command palette (⌘+K)
• ✅ Static export for GitHub Pages

• ✅ Local AI: Transformers.js integration (runs in browser)
• ✅ Mock AI: Offline demo mode with pre-coded responses
• ✅ Multiple Providers: Pluggable AI backend system
• ✅ Smart Fallback: Automatically falls back to mock mode on errors
• ✅ Language Detection: Automatically detects target programming language
• ✅ Status Indicators: Real-time AI model loading/ready status

You can switch providers anytime via Settings (⌘+K).

• ✅ Instant responses for demos
• ✅ Works offline
• ✅ Pre-coded examples for common tasks
• ✅ No setup required
• Best for: Trying Hexa, demos, offline use

• Runs entirely in your browser
• No backend required
• Privacy-first (all processing local)
• Uses Xenova/CodeGen-350M model (~350MB download on first use)
• Status indicator shows loading/ready state
• Progress updates in browser console
• Best for: Privacy-conscious users, offline AI after initial download
• Note: First-time load may take 3-7 minutes depending on connection

• Django/FastAPI integration ready
• See docs/BACKEND_API.md for implementation guide
• Production-grade AI (GPT-4, Claude, etc.)
• Best for: Production deployments, best quality responses

1. Press ⌘+K (Mac) or Ctrl+K (Windows/Linux)
2. Click on Transformers provider
3. Open browser console (F12) to see download progress
4. Wait for model download (~350MB, one-time, 3-7 minutes)
5. Console will show: ✅ Model initialized successfully
6. Status will show: "🤖 AI Ready"

Note: Downloads from huggingface.co - check your network if it fails!

• WebSocket streaming for real-time AI responses
• Add more keyboard shortcuts
• Add code execution capability
• Multi-file editor support
• User authentication
• Save/load conversation history
• Model selection UI
• Fine-tuned models for specific languages
