// Why I built this

I've been using Claude Code daily since January 2025. After 25,000+ AI actions, I realized I had zero proof of what actually happened. The AI's own logs? It can edit those. Git history? Doesn't capture the thinking process.

I wanted something that works like a dashcam — always recording, can't be tampered with, and there when you need it.

If you use Claude Code or Cursor for client work, team projects, or anything where you need to show what your AI actually did — this is for you.

// Three Trust Layers

Each layer adds a guarantee the layer below cannot provide.

01

Merkle Tree
