13F Insight

13F Insight is a specialized research platform that lets you analyze institutional investment data by asking questions in plain English. Instead of digging through complex SEC filings and spreadsheets, you can simply type a question like 'What sectors does this fund focus on?' or 'Who added Amazon stock last quarter?' The tool's AI agent, powered by Anthropic's Claude models, scans millions of real SEC filings dating back to 1999 and returns sourced, data-driven answers. It covers over 30,000 filers and more than 4 million filings, making institutional investment research accessible without financial data expertise.

The tool works through a simple three-step process: pick a fund, stock, or insider from the platform; ask a natural language question in the sidebar AI agent; and receive a detailed response with specific data points pulled directly from SEC documents. It offers different pricing tiers that provide access to increasingly powerful AI models (Haiku, Sonnet, or Opus) with varying daily question limits. Beyond the AI chat, the platform also provides Smart Money Alerts for unusual trading activity and publishes regular research reports on major fund movements.

This tool is ideal for investors, financial analysts, journalists, and anyone who needs to track institutional investment activity but lacks the time or resources to parse dense SEC documents manually. Use cases include due diligence on investment managers, tracking hedge fund moves for market signals, researching specific stock ownership among major funds, and getting quick summaries of portfolio changes without manual data crunching. It turns a traditionally tedious research process into a conversational, immediate experience.
