Public company data, the way it should be.
Free and open.

Revenue, margins, segments, a decade of history — for every US public company, in plain English and traceable to the filing.

Public, in every sense.

Public companies file hundreds of pages a quarter, written by lawyers. It’s all technically public — your data, by law — but in practice only analysts read it. OpenCapital does the reading and hands you the numbers, the segments, the management commentary, and the source link, in plain English.

No ads, ever.
No selling user data, aggregated or otherwise.
AI assistants welcome — no subscription required.
Every number links back to the gov. filing it came from.

“What’s reporting this week from companies I follow?”

Earnings weeks are the only days new information about a company actually arrives — the other 240 are just price noise. Here’s the week ahead, sorted by name.

“How fast is Airbnb’s booking volume growing — and at what price per night?”

The numbers that decide a thesis on Airbnb, Uber, or DoorDash — bookings, daily rates, take rate — aren’t in the income statement. They’re in management’s letter, named differently at every company. One prompt now searches every filing.

Hand your portfolio to your AI.

Link a brokerage once and your AI assistant can ask the same filings-grade questions about the names you actually own — refreshed as each new filing comes in.
