A better interface for public-company filings.
When someone needs to work with a public-company filing, I want OpenCapital to be the place they choose.
Public filings take too much work to use.
OpenCapital started with a frustration that has become familiar: you ask an AI assistant about a company's revenue or margins, and it hands back a confident, specific number that turns out to be hallucinated, appearing in no filing anywhere. And it points you to nothing: no link to the actual SEC filing, no source to check it against.
Finding the real figure yourself wasn't much easier. Public companies file the truth every quarter, in exhaustive detail, and all of it is public by law. It's buried in hundred-page documents on SEC EDGAR, written in legal prose that almost no one outside a professional analyst has the time to read. The information is technically public and effectively hidden.
OpenCapital was built to close that gap. We parse every 10-K, 10-Q, and 8-K into structured numbers, label them in plain English, chart their history, and keep every value one click from the filing it came from. The same dataset powers a Model Context Protocol (MCP) server, so the AI tools people increasingly research with can pull from the source instead of guessing.
The project is independent and self-funded.
A few rules we don't break.
These principles shape what we build, what we charge for, and how OpenCapital earns trust.
Research without recommendations
OpenCapital shows what a company reported and links straight to the filing. It does not rate securities or tell you what to buy, sell, or hold.
Public research is available without a subscription
Company pages, filings, metrics, charts, and source links are available without a subscription. Paid plans add workflow capacity around that record.
Every number is verifiable
Each figure links back to the exact filing it came from. The methodology explains how OpenCapital collects, standardizes, and updates the data.
Clear commercial terms
Pricing describes the limits directly. Subscriptions are easy to manage, and organizations receive terms based on seats, API access, volume, and commercial use.
How OpenCapital makes money.
Individual researchers can subscribe for higher workflow limits, including unmetered AI research and an unlimited watchlist. Organizations contact us for per-seat access, API access, higher-volume use, and commercial terms.
OpenCapital does not run ads, sell user data, accept payments to feature stocks, or alter screener results for sponsors. Subscriptions and organization products fund the business.
What OpenCapital is not.
- Not a broker, investment adviser, or financial planner. Nothing on the site is a recommendation to buy or sell any security.
- Not affiliated with the SEC, with any company covered here, or with any market-data vendor.
- Not a real-time trading terminal. Prices are end-of-day. OpenCapital is for understanding a business and building a thesis, not for chasing the next tick.
