What it does

Zero infrastructure — the tab is the server. A browser-only reimagining of NanoClaw with the same premise: small enough to read and understand, built for one person. Paste an Anthropic key and start. The key and your chat history live in browser storage, so this isn't for a shared machine. The author opens the README warning that any coin, token or social account claiming association with the project is fraudulent. Quiet since February 2026. MIT.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
