Beautiful enough to want open
Most AI looks like a cockpit. Hearth looks like a warm room.
The ember, waiting by the fire.
A conversation that reads like a letter.
Free · Private · Runs on your computer
Hearth is a beautiful AI that lives on your computer — private, unlimited, and free. No account. No internet. Nobody watching. Just you and a quiet, intelligent presence by the fire.
No install in Chrome — or a native app for macOS, Windows & Linux
The opposite of the cloud
Every other AI lives in someone else's data center — metered, logged, one outage from gone. Hearth is the other thing entirely.
Every word stays on your machine. No servers, no logs, no one reading over your shoulder. Privacy isn't a setting — it's how Hearth is built.
No subscription. No message caps. No meter ticking. Hearth runs on your own hardware, so there's simply nothing to bill.
On a plane, in a cabin, off the grid. Once it's set up, Hearth needs the internet about as much as a candle does.
No account, no login, no tracking. Hearth is an app that lives with you — not a service you rent.
Beautiful enough to want open
The ember, waiting by the fire.
A conversation that reads like a letter.
Three steps, no jargon
In your browser, or as a one-file app — no setup, no terminal, no account. It just opens, with an AI already waiting inside.
Hearth checks your computer and quietly loads the right model — Fast, Smart, or Genius. You don't choose jargon; you choose how clever you want it.
Ask anything. The answer arrives in seconds — entirely offline, entirely private. Often before a cloud app would've finished loading.
Why this exists
The cloud was never yours. Your AI shouldn't live in someone else's data center — metered, logged, and one outage from gone. Hearth brings it home: warm, private, and yours. A light you own, in a cloud you don't.
Free, forever. Start in your browser — or keep it as an app.
No download, no install. Open Hearth in Chrome and start talking. The AI runs inside your tab, entirely private.
Or keep it forever as a native app
The browser version is live now — the Mac, Windows & Linux apps are in active, in-the-open development. Star it on GitHub to follow along.
