About 13F.chat
13F.chat tracks quarterly SEC 13F filings from 132 hedge fund and institutional managers, showing what each one bought, added and sold in dollar terms, with AI-written explanations of each move. Views are organised by manager, industry and stock, and daily public research pages cover well-known portfolios.
13F.chat is a web-based research tool for individual investors who follow institutional positioning. Form 13F filings are published every quarter by investment managers with more than $100 million in US equity assets, but the raw filings are long tables that are hard to compare. 13F.chat turns them into readable views: for each of 132 tracked managers it lists new positions, additions, reductions and exits in dollar terms, and adds a short AI-generated explanation of why a move may or may not still be relevant. Coverage spans 25 industries and roughly 500 US stocks. A 13F Discovery Radar highlights where capital appears to be rotating between sectors, and daily public research workspaces focus on individual portfolios such as Berkshire Hathaway. The site follows a freemium model with free public pages. 13F data is quarterly and published with a delay, so it suits longer-term research rather than short-term trading.
