13F Insight

What is 13F Insight?

13F Insight is a research site for retail investors who want to follow what institutional managers hold and trade. It indexes SEC EDGAR data: quarterly 13F-HR holdings from 1999, 13D/G beneficial ownership filings from 1994 and Form 4 insider transactions from 2003. You can browse filers, stocks, filings, activist positions and insider trades, then compare quarter-over-quarter changes for any manager. An AI agent sits on every filer, stock and insider page, so you can ask in plain English what a fund bought last quarter or who holds a stock, and get answers grounded in the filing data. Watchlists, filer groups and alerts help you follow the names you care about. The service has a free tier plus Standard and Pro subscriptions that raise the history depth, API limits and daily AI questions. Filings arrive up to 45 days after quarter end, so the data is not real time.

Use cases

• Track institutional holdings by quarter
• Follow insider Form 4 trades
• Monitor activist 13D/G filings
• Ask an AI about any fund or stock
• Compare holdings across multiple funds
• Build watchlists of filers and stocks

Who it's for

Why use 13F Insight

• Filings, activist stakes and insider trades sit in one place instead of across several EDGAR searches.
• Plain-English questions to the AI agent save time on spreadsheet work for common holdings checks.
• A free tier lets you try the data and the agent before paying.
• Higher tiers use stronger models and raise daily question and API limits.
• Terms state the content is informational and not investment advice, which keeps expectations clear.

5. Upgrade to Standard or Pro for longer history, more AI questions and the advanced tools.

13F Insight limitations

• 13F filings arrive 45 days after each quarter ends, so the holdings data is not real time
