HistoryMind 作者： Noah Albert

Most browser analytics tools tell you how much you visited a site. HistoryMind tells you what it means.

It reads your browsing history, clusters your reading by topic, and then asks: what related areas are you systematically ignoring?

Features:
- Topic clustering with engagement depth (deep, moderate, or surface)
- Blind spot detection: finds adjacent knowledge areas you should be exploring
- Breadth score: rates your intellectual diversity on a 1-10 scale
- 5 concrete recommendations: resources, thinkers, or questions to explore
- Privacy-first: your history goes directly from your browser to your own Anthropic API key. Nothing is ever sent to any server we control.

Setup:
1. Install the extension
2. Get an Anthropic API key from console.anthropic.com (free to sign up, about 1-5 cents per analysis with Claude Haiku)
3. Click the HistoryMind icon, enter your key, choose a time window, and click Analyze
