🧠 Neuron Budget
AI features use a shared daily neuron budget powered by Cloudflare Workers AI. Each action has a neuron cost. When the budget runs out, AI features pause until midnight UTC.
| Feature | Cost | Model |
|---|---|---|
| Chat / Agents | 3 neurons | granite-4.0-h-micro |
| Summarize | 3 neurons | granite-4.0-h-micro |
| Code Review | 9 neurons | llama-3.1-8b |
| Image Generation | 58 neurons | FLUX-1-schnell |
| Vision Analysis | 65 neurons | llama-3.2-11b-vision |
Limits: 800 neurons per IP per day. 8,000 neurons globally per day. WASM tools (Decoder, Env Inspector) are free and unlimited.

❓ FAQ
Is this really free?
Yes! The site runs on Cloudflare's free tier. WASM tools work offline. AI features share a daily neuron budget to keep costs manageable.
Do you store my data?
No tracking, no analytics, no cookies. Chat history is stored only in your browser's localStorage. The Env Inspector never sends your files anywhere.
Why does AI chat show "Local Mode"?
Locally, the Workers AI binding isn't available. The agents return demo messages. Deploy to Cloudflare Pages to get real AI responses.
Can I use the MCP tools in VS Code?
Yes! Install the Rust MCP server binary, add it to your MCP client config (Claude Desktop, Copilot, Cursor), and all 14 tools become available.
What browser do I need?
Any modern browser with WASM support: Chrome 57+, Firefox 52+, Safari 11+, Edge 16+. Voice output needs the Web Speech API.
How do I report bugs or suggest features?
Open an issue on GitHub. Bugs are just villains waiting to be unmasked!
