13F.chat

13F.chat is an advanced AI-powered research terminal designed to transform 13F filings into actionable insights for quantitative investing. This tool allows investors to analyze the holdings of major U.S. fund managers through an interactive chat interface that processes complex SEC data. Its primary function is to convert investment theses, constraints, and financial concepts into fund screens, portfolio analyses, and portfolio optimization paths ready to be tested from a computer or any device.

The platform utilizes live portfolio reasoning technology to break down the composition of high-profile funds such as Berkshire Hathaway, Scion Asset Management, or the S&P 500. Through an AI engine, 13F.chat synthesizes current data and provides an evidence dashboard detailing critical metrics such as manager conviction, turnover rate, and overlap between different portfolios. Its technical approach combines public data analysis with AI models that enable natural language queries regarding risk, factor style, and the results of specific strategies.

Key capabilities and practical benefits include:

• Real-time holdings analysis: Access to current positions and capital movements across more than 114 funds, including indices like the Nasdaq-100.
• Optimization strategies: Enables running and comparing models such as the Momentum Screen, Value Screen, and Combo Equal to evaluate Alpha and the Sharpe ratio.
• Identification of high-conviction ideas: Filters managers whose top 10 holdings concentration exceeds 60%, facilitating the search for powerful investment signals.
• Customized AI summaries: Generation of reports on asset weight changes and alerts on significant movements in specific tickers.
• Alpha and risk detection: Tools to build portfolio versions with lower drawdowns and understand which periods best explain the risk-return trade-off.

For professional users or active retail investors, the unique value of 13F.chat lies in its ability to contextualize data that, due to regulations, is typically published with a lag. The AI helps identify which portfolio changes remain relevant and complements the view of long positions with sector analysis and peer overlap. It is a robust solution for those seeking to perform deep fundamental research and data-driven portfolio management, eliminating the need to manually process thousands of SEC filings.
