13F Insight

What it does

Institutional investors managing over $100M must disclose holdings to the SEC quarterly, but parsing thousands of filings manually is impractical. 13F Insight ingests 380,000+ 13F filings, 4.3M+ insider transactions, and 480,000+ activist filings dating back to 1999. AI-powered Smart Money Alerts detect unusual patterns — massive new positions, complete exits, double-downs — and generate plain-language analysis. Ask questions in natural language, find consensus holdings across fund groups, or merge portfolios into one view. Free tier available, no credit card required.
