AI research terminal for exploring SEC 13F filings and tracking what hedge funds and top managers hold.
13F.chat is an AI research terminal built around SEC Form 13F data, the quarterly disclosures that hedge funds and other large institutional investors file listing their U.S. equity holdings. Users can track what named managers bought or sold, see estimated cost of positions, and get plain-language explanations of portfolio moves, with the site openly noting that 13F data is public, quarterly, and delayed rather than real-time, and that its outputs are research aids rather than financial advice. The product exposes machine-readable entry points, including an API catalog and an MCP server card, suggesting it's built to be queried by other software and AI agents, not only browsed by people. No pricing was visible in what could be fetched from the site during research.
No price figure could be found anywhere in the fetchable content of the site; a pricing page is linked but its content did not resolve during research.
Use tool ↗13F.chat turns a genuinely useful but clunky public data source, quarterly SEC 13F filings, into something searchable and explainable in plain language, with the honest caveat that the underlying data is always weeks old by nature of the filing requirement, not a limitation of the tool itself. Its API and MCP-server exposure suggest it's built as much for agents and integrations as for a person browsing directly, but no pricing could be confirmed during this research.
Watch out: 13F data is quarterly and delayed by design; this tool can't make institutional holdings data more current than the underlying SEC filings allow.
