13F Insight is an AI-powered research tool that lets you ask plain‑English questions about SEC 13F filings and get sourced answers drawn from real filings—no spreadsheets required.
What is 13F Insight?
13F Insight is a web platform that indexes over 5 million SEC 13F filings from 30,000+ institutional investors, dating back to 1994. Instead of manually combing through filing tables, users type natural‑language questions (e.g., “What sectors does Berkshire focus on?”) and the AI agent returns a concise, citation‑linked answer using real holdings math and filing data. The platform runs entirely in the browser and is developed by 13finsight.com.
Key Features
- AI‑powered Q&A — Ask any question about a fund, stock, or insider in plain English; the agent reads the underlying 13F and returns a sourced answer with specific percentages and filing dates.
- 30,000+ filers tracked — Browse every institutional investor that files 13F, from Berkshire Hathaway to small advisory firms, each with a dedicated page showing holdings, top positions, and quarterly changes.
- Real‑time filing feed — See the latest 13F filings as they are submitted, with fund name, asset size, and number of positions (e.g., “Blom & Howell Financial Planning, Inc. – 61 positions – $101.85M”).
- Filer spotlight — For major filers like Berkshire Hathaway, get a condensed summary (AUM, top 5 holdings, Q/Q change, notable moves) and an interactive AI chat embedded on the page.
- Historical data since 1994 — All filings indexed for long‑term trend analysis, accessible through the same AI‑agent interface.
- Free tier with no credit card — Ask two questions without signing up; create a free account for five questions per day.
Who is it for?
- Individual investors who want to quickly check what a famous fund (e.g., Berkshire Hathaway) owns without reading through dense SEC documents.
- Financial analysts who need to compare portfolios across multiple filers (e.g., “Compare Buffett and Burry's portfolios”) and get instant, citation‑backed breakdowns.
- Journalists and researchers tracking institutional moves (e.g., “Who added AMZN this quarter?”) for articles or reports, with verifiable sources.
- Portfolio managers conducting peer‑group analysis – for instance, scanning which hedge funds are piling into a specific stock, then drilling into their 13F‑disclosed positions.
What can you do with 13F Insight?
- Ask about any fund: Type “What sectors does Berkshire focus on?” and get a response showing Financial Services 38.4%, Technology 24.1%, along with specific filing citations.
- Compare multiple portfolios: Ask the AI to contrast two funds (e.g., “Compare Buffett and Burry's portfolios”) and receive a side‑by‑side analysis of top holdings, sector weights, and recent trades.
- Track insider or stock moves: Search for a specific stock (e.g., NVDA) and ask “Who's been adding NVDA this quarter?” to see which filers disclosed new positions and at what size.
- Monitor filing activity live: Scroll the latest filings feed to see which funds just submitted their quarterly 13F, with direct links to their holdings and AI chat.
