Every dataset is on the website for both plans. The differences are where your AI can read, and how deep the pages go.
| Feature | Basic$0 | Premium$29/mo |
|---|---|---|
| In your AI | ||
| ClaudeAdd 13F.ai to Claude in about a minute, with no API key and no code. Works on every Claude plan, Free included (a Free account can add one custom connector). On Team and Enterprise, an Owner adds it for the organization first, and each member then connects. | Congress data | All datasets |
| ChatGPTAdd 13F.ai to ChatGPT in about a minute, with no API key and no code. Install it from ChatGPT's plugins directory, where 13F.ai is listed for the United States. In a work or school workspace an administrator decides which plugins members can install. Where it can't be installed, adding it as a custom MCP server works with developer mode (ChatGPT Pro, Business, Enterprise and Edu; we also used it on the free plan in October 2026). | Congress data | All datasets |
| Microsoft 365 CopilotComing soonNot available yet: 13F.ai is not in Microsoft's connector gallery. Once it is, your Microsoft 365 administrator turns it on and each person signs in from Copilot. Work or school accounts only. Each person needs a Microsoft 365 Copilot license (Microsoft lists federated connectors for the Copilot add-on and Microsoft 365 E7, not for Copilot Chat on its own), and an administrator turns the connector on. The free Copilot app with a personal Microsoft account isn't covered. | Congress data, coming soon | All datasets, coming soon |
| GeminiAdd 13F.ai to Gemini as a custom app, with no API key and no code. Google offers custom apps to people 18 or over in the US, in English, with a personal Google Account (not work or school) and Keep Activity on. You add the app on the web, and it then works in the Gemini mobile app. Google doesn't say which Gemini plans qualify. | Congress data | All datasets |
| Local AI models (MCP)Open WebUI, LM Studio, Claude Code and any other app that supports MCP, the standard way to give an AI app tools and data. That includes models that run on your own computer. They are part of the Premium plan, and sign in with your account or an API key. | Not included in Basic | Included in Premium |
| Datasets your AI can readHow many of the datasets on 13F.ai your assistant can read. Every one of them can be browsed on the website, on both plans. | 10 (Congress, the executive branch and FINRA short selling) | 44 |
| Usage limitsRequests your assistant or code may make. A Basic account may make 30 a minute and 500 a day. A Premium account may make 60 a minute, per key or account, with no daily limit. | 30/min, 500/day | 60/min, no daily limit |
| On the website | ||
| Every dataset, feed, fund, stock and member pageA Basic and a Premium account can both browse every dataset on the website. The rows below are where the plans differ on those same pages. The full list of datasets is on the Feeds page. | Included in Basic | Included in Premium |
| Feed historyA feed page lists the 50 newest rows that match your filters. A Premium account can load older rows below the table, up to 10,000 in all, and can download up to 10,000 rows of a feed as a CSV file. A list sorted by a column stays inside the date range shown. Lobbying and contracts, Capitol Hires, Short interest, Daily short volume, Wikipedia page views, App store ratings, Fails to deliver and Stock splits keep one fixed table, and say so on the page. The REST API and your AI assistant page through more. | Latest 50 | Full history |
| Fund positionsA fund's full list from its latest 13F, searchable by name or ticker, sortable and paged, with options (puts and calls) listed separately. Basic accounts see the 50 largest, so a fund with 50 or fewer positions and no puts or calls shows all of them to everyone. | Top 50 | Every position, puts and calls |
| 13F holders of a stockEvery fund that reports the stock, with shares, value, share of that fund's portfolio and change since the quarter before. Calls and puts are listed separately. Basic accounts see the 10 largest on the stock page and the 50 largest on the public 13F holders list. | Top 10 | Every holder |
| AI summaries of 13F changes, 10-Qs and IPO prospectusesWritten by an AI from the filing's own text and checked against it. 13F: two to four sentences on what each fund changed, at the top of every fund page. 10-Q: a few plain bullets on what changed since the prior report, on stock pages, with a link to the filing. IPO: the main points of each prospectus (S-1 or F-1), on the IPO page and the company's stock page. Basic and Premium accounts both have them. | Included in Basic | Included in Premium |
| Holdings comparison of two quarters, filings since quarter endA comparison of a fund's holdings, not an AI feature. Pick any two of the quarters we keep and see each position as new, added to, trimmed, exited or unchanged, with the change in shares and value. Next to a fund's positions, any Schedule 13D or 13G the fund filed on that company since the quarter ended; on a stock, Form 4 insider buying and selling since then. 13F reports lag the quarter by up to 45 days, these filings are newer. Basic accounts see a fund's biggest changes against the previous quarter on the fund page. | Not included in Basic | Included in Premium |
| ThemeBasic accounts use the light theme. A Premium account can choose light or dark, and the choice is remembered on the account. | Light | Light or dark |
| Alerts and data | ||
| EmailEvery account gets one email a week with what changed on its watchlist, and a line when a fund it follows files its 13F. Premium can choose a daily email instead, around 7 AM Eastern, with no email on a day with nothing new, and it lists a followed fund's biggest new, added, trimmed and exited positions with an AI summary of the changes. | Weekly | Daily, with the AI summaries |
| Private company watchWatch up to 50 companies that aren't publicly traded, such as Stripe or Databricks, and get an alert when one files an S-1 or F-1 to go public (or prices or withdraws), a Form D, an FTC merger notice or a deal filing. | Not included in Basic | Up to 50 |
| API keys, CSV downloads, bulk filesA personal API key from your account page for your own scripts and apps (the same key works for the MCP server), a Download CSV button on the main tables (up to 10,000 rows), and whole datasets as gzip CSV files refreshed every night: the latest 13F filings and positions, 13F history summaries, Congress trades and insider trades. | Not included in Basic | Included in Premium |
| No sponsor placementsBasic accounts see sponsor and partner placements, never on congressional trades, bills, PAC donations or FINRA short selling data. | Not included in Basic | Included in Premium |

Common questions
How does the free trial work?
You get 7 days of Premium free. A card is required. You are charged when the trial ends unless you cancel first, and we email you 3 days before. One trial per person.
What if my AI asks for Premium data on Basic?
It answers the Congress part and says the rest is part of Premium. Nothing is charged and nothing breaks. You can still read every dataset on the website.
How do I cancel?
Any time, in one click, from your account page. Cancel during the trial and you are not charged. Later, you keep Premium until the period you paid for ends.
How do payments and refunds work?
Cards, in US dollars, through Stripe. We never see your card number. Payments are not refundable except where the law requires it (Terms, section 4.7).
Can I use it for work or publishing?
Not on Basic or Premium. Every individual plan, free or paid, is for your own personal, non-commercial use (Terms, section 6). For a business, client or publication, ask about a commercial license. Commercial licensing.

No. 13F.ai republishes public filings and links every row to its source. Filings can be late, incomplete or wrong. Read the disclaimer.
