First Impressions and Onboarding
Upon visiting 13finsight.com, I was greeted by a clean, data-rich dashboard. A live feed of institutional moves scrolls at the top — I saw Berkshire Hathaway adding Apple, Bridgewater trimming Nvidia, and Citadel Advisors initiating a position in Palantir. The layout immediately signals that this tool is built for speed and insight. Below the feed, a Filer Spotlight highlights a specific fund; when I clicked on Berkshire Hathaway, the page displayed total AUM ($312.4B), number of holdings (41), quarter-over-quarter change (-2.1%), and top five holdings with percentage changes. The entire experience felt like having a Bloomberg terminal, but for 13F filings only — and with an AI agent ready to answer any question.
Core Functionality and AI Agent
The standout feature is the AI agent that rides along on every page. I typed “What sectors does Berkshire focus on?” and within seconds received a sourced answer: Financial Services at 38.4%, Technology at 24.1%, with Apple alone making up ~22% of total holdings. The agent cited the specific SEC filing (13F-HR dated Feb 14, 2026) and even noted that Buffett trimmed AAPL by 6% for the fourth straight quarter. Every answer includes real citations — no hallucinated tickers or vague summaries. The tool indexes over 5 million filings from 30,000+ filers going back to 1994, so historical queries are possible. I also tested asking “Compare Buffett and Burry's portfolios” and received a side-by-side breakdown with links to each fund's latest filing. The agent handles natural language queries effortlessly, whether about sectors, top moves, or insider trading.
Pricing and Market Position
Pricing is not fully listed on the website, but the free tier is generous: two questions free without any signup, and five questions per day with a free account. A “See pricing” button suggests there are paid plans beyond that, likely for higher usage or data exports. Compared to competitors like WhaleWisdom (which offers portfolio tracking but lacks conversational AI) or Dataroma (which aggregates 13F data but requires manual filtering), 13F Insight’s AI agent sets it apart. It also offers a live flow showing real-time changes across funds, which is a feature I haven’t seen matched elsewhere. The tool is clearly aimed at retail investors, analysts, and anyone tracking institutional moves — it eliminates the need to parse complicated SEC filings or build Excel models.
Strengths, Limitations, and Verdict
Strengths: The AI agent delivers accurate, sourced answers in seconds. The interface is intuitive, and the live feed keeps you updated on whale movements. The breadth of data (since 1994) allows for long-term trend analysis. Limitations: The free tier’s question cap (two without account, five per day with account) may frustrate heavy users. Also, the AI agent currently only covers 13F filings — it does not include 13D/G or other SEC forms, so insider transaction coverage is limited. Finally, pricing for unlimited access is not transparent. Despite these drawbacks, for anyone who needs to quickly understand what top investors are doing, 13F Insight is a powerful time-saver. I recommend it for retail investors who want to track institutions without manual data wrangling, and for professionals who need rapid answers during earnings season.
