Questions

What is 13F Pro?

13F Pro is AI stock research built on official SEC filings, for long-term investors.

Every quarter, investment managers with more than $100 million must file a Form 13F with the SEC listing the stocks they own. We collect those filings for 8,700+ funds, so you can see what they bought and sold. We combine that with each company's own financial reports to score how strong the business is.

Where does the data come from?

From SEC EDGAR, the government's official filing system: 13F holdings for funds, 10-K and 10-Q reports for company financials, and Form 4 filings for insider buying and selling.

Hedge fund holdings arrive once a quarter, up to 45 days after the quarter ends, because that is when the law requires funds to file. Stock prices are live.

What is the AI score?

A 0–100 rating of business quality, recalculated every day. It looks at things long-term investors care about, such as return on invested capital, free cash flow, balance sheet strength and growth.

Everyone sees a company's score, its sub-scores, how it has changed over time and what is driving it. A free account sees ranks 51–100 of the AI rankings; Pro sees every rank, including the top 50.

What does Pro unlock that Free doesn't?

Free includes hedge fund holdings for 8,700+ funds, insider trades, each company's quality score with its history and drivers, price charts with chart patterns, AI rankings 51–100, a 5-stock watchlist that shows up in the Daily Ticker email, and 5 general phone alerts.

Pro tells you when something changes in a stock you own or watch. Add up to 300 stocks to your watchlist and your phone gets an alert when:

  • Its Quality Score is upgraded or downgraded
  • It files a new 10-Q or 10-K
  • A new chart pattern forms or breaks out on its price chart
  • An insider buys ($25K or more) or sells ($100K or more) on a Form 4
  • A hedge fund opens, exits or changes a big stake in its latest 13F
  • A member of Congress discloses a trade in it
  • The company reports earnings
  • There is news on it, or it moves 3% or more to a new intraday high or low

You can also get an alert when a fund you watch files its 13F, and an email when a fund you follow files or a large company you follow reports earnings.

Pro also adds:

  • Full company research: the whole 10-Q and 10-K breakdown, key metrics, ratios, full statements, holders and every Congress stock trade
  • Every AI rank, including the top 50, and the rankings track record
  • The AI Screener (25 screens a month) and the full Chart Patterns screener
  • 10 two-pager report PDFs a month and full 10-page research reports
  • The live AI Bull Pen, full briefings and the full AI Portfolio
  • Excel exports (first 200 rows) and Hedge Fund Overlap
  • All 8 tools in the MCP connector for Claude and ChatGPT (100 questions a day)

Pro+ adds Portfolio Builder, ML cluster analysis on every company, the AI Cluster Time-Lapse, unlimited AI screens, exports and report PDFs, and institutional PDF reports.

What is the MCP connector?

It puts 13F Pro inside Claude and ChatGPT. Add the connector once, sign in with your 13F Pro account, then ask your AI about any stock, fund, insider, 5% stake or Congress trade. The answer comes from 13F Pro's own data, with a link back to the page it came from.

Free accounts get stock lookup, 10 questions a day. Pro opens all 8 tools, 100 questions a day. Pro+ is unlimited. It is read-only, and we never see your chats.

Is there a free trial?

Yes. Pro and Pro+ both come with a 7-day free trial if you have never subscribed before. You get everything in your plan from the first minute.

Checkout asks for a card so your subscription can continue without interruption after the trial. You are not charged during the trial, and if you cancel before it ends you pay nothing.

One free trial per member, on either plan. If a friend invited you, your trial is a full month instead of 7 days (see below).

Is there a new-member discount?

Yes. If you subscribe within 24 hours of creating your account, and have never subscribed before, your first payment is discounted. It is applied automatically at checkout, with no code to enter.

PlanRegular priceYour first payment
Pro monthly$9.99/mo$4.99 (50% off month 1)
Pro annual$79.99/yr$74.99 ($5 off year 1)
Pro+ monthly$24.99/mo$12.49 (50% off month 1)
Pro+ annual$199.99/yr$187.49 ($12.50 off year 1)

After the first payment you pay the regular price. On Pro, the 7-day free trial comes first: you pay nothing during the trial, and the discounted payment is your first charge after it ends. Pro+ has no trial, so its discounted payment is charged when you subscribe. The checkout page shows the exact amount before you pay.

How does Refer a Friend work?

Once you have an account, share your personal link from the Refer a Friend page. When a friend creates a new 13F Pro account through it:

  • Your friend gets a free month of Pro.
  • You get a free month of Pro for every friend who joins, with no limit. If you are already paying, it comes off your next bill. If you are on Free, you can start a free month of Pro, and the rest of your months are waiting when you subscribe.

A free month starts through the same checkout as the trial, so it asks for a card, and you are not charged during it. Your friend needs to be new to 13F Pro, and you can't refer yourself.

How do I cancel?

Anytime, from the Billing page in your account. Once you subscribe or start a trial, a Billing Portal button appears there where you can cancel, change your card or download invoices.

Is this investment advice?

No. 13F Pro is a research tool that organizes public filings and data to help you make your own decisions. We don't tell you what to buy or sell.
