Ask an AI agent about SEC 13F holdings of funds and stocks
About 13F Insight
13F Insight is a research site for people who want to understand what institutional investors own. It indexes SEC 13F filings from more than 30,000 filers, covering hedge funds, asset managers and other large holders, with data going back to 1994. Users can browse filers, stocks, 13F activity and insider records, then ask an AI agent questions in plain English about any fund, stock or insider.
The product's main difference is that the agent answers from the filings themselves, with citations to the specific 13F-HR documents and holdings math rather than vague summaries. Examples on the site include asking which sectors Berkshire Hathaway focuses on or who added a given stock in the latest quarter. The agent is available on every page, and a few questions can be tried without an account.
The site suits investors, analysts and researchers who want to follow smart money without building spreadsheets from raw EDGAR data. It also publishes research notes and guides on reading SEC filings.
