AI that never
leaves your home.
Hearth runs powerful AI models locally on your desk. Your conversations stay yours. No cloud. No tracking. Just intelligence, in a quiet box.
Why Hearth?
Intelligence shouldn't cost your privacy.
100% Local Processing
Every model runs on Hearth's custom silicon. Your voice data never touches the internet. It stays in the room, in your house, under your control.
Privacy by Design
No microphones are active unless you tap Hearth's top. A physical mute switch kills the audio circuit. The LED ring goes dark. You decide when AI listens.
Always Ready, Zero Latency
Because Hearth processes locally, responses are instant. No waiting for a cloud round-trip. Commands execute in under 200 milliseconds, every time.
Expandable Intelligence
Install new capabilities over time. Hearth supports plugins for music, smart home, coding assistants, and more. Your device grows with your needs.
Silently Beautiful
Zero fans. Zero noise. Hearth uses a solid-state heatsink and passive cooling. It's the quietest device on your desk — and the smartest.
Works With Everything
Connect Hearth to your lights, thermostat, speakers, or security system. It speaks Matter, Zigbee, and Thread. One device replaces five hubs.
Technical Specifications
Engineered for privacy. Built for performance.

Frequently Asked Questions
Everything you want to know before bringing Hearth home.
Yes. Hearth processes everything locally on its custom Neural Engine. Your voice audio is never sent to the cloud. We don't store recordings, we don't train on your data, and we can't see your conversations. The only time Hearth connects to the internet is when you explicitly ask it to — like checking the weather or updating a plugin. And even then, only the minimum data needed for that request leaves your home.
Hearth remembers everything. When power returns, it wakes up exactly where it left off — your settings, your routines, your installed plugins. The encrypted storage retains all data without power. Hearth also includes a small capacitor that gives it 10 seconds to save state and shut down gracefully during unexpected outages.
Absolutely. Hearth Home and Hearth Studio support Matter, Thread, and Zigbee natively — meaning they work with thousands of devices from brands like Philips Hue, Ecobee, August, and many more. You can control lights, thermostats, locks, cameras, and speakers all from one place. Hearth Lite supports Wi-Fi devices and Bluetooth peripherals.
Models are installed through the Hearth app on your phone or web dashboard. Browse the local model library, select what you want, and Hearth downloads it over Wi-Fi — encrypted and verified. Updates are automatic for free models. You can also sideload custom models if you're on the Studio plan with developer access. Everything runs offline once downloaded.
Hearth supports over 40 languages out of the box, including English, German, French, Spanish, Japanese, Mandarin, and Arabic. Each language model runs entirely locally. You can switch languages on the fly, and Hearth handles mixed-language conversations naturally. Additional languages are added regularly through free updates.
Every Hearth comes with a 30-day money-back guarantee — no questions asked. If it's not right for your home, send it back. The Home and Studio models include a 2-year warranty covering hardware defects. Lite carries a 1-year warranty. We also offer extended protection plans for Studio owners who want peace of mind.
