Discover your intellectual blind spots. HistoryMind analyzes your browsing history with Claude AI and reveals the knowledge gaps hiding in plain sight.
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?
- Topic clustering — Groups your browsing into 4-7 intellectual categories with engagement depth (deep/moderate/surface)
- Blind spot detection — Finds 4-5 adjacent knowledge areas you should be exploring but never do
- Breadth score — Rates your intellectual diversity on a 1-10 scale
- Specific recommendations — 5 concrete resources, thinkers, or questions to explore
- Privacy-first — Your history goes directly from your browser to your Anthropic API key. We never see it.
