Overview

13F.chat is a web-based research platform that transforms SEC Form 13F filings into actionable portfolio intelligence. It tracks quarterly disclosures from institutional investment managers, presenting what top managers bought, added, and sold in dollar terms, along with estimated cost bases. The platform includes a 13F Discovery Radar that visualizes capital rotation across managers, industries, and high-conviction stocks.

Full Description ▼

It provides an AI Smart Money Copilot that explains whether a given manager's move still matters, using natural language Q&A over aggregated 13F data. Users can create multi-13F or single-13F workspaces, explore smart money holdings, and access daily public research on notable funds.

13F.chat aims to offer institutional-grade research to individual investors, with coverage of over 130 managers, 25 industries, and 500 stocks in the latest quarter. The platform emphasizes informational and research purposes and is not investment advice.
