Works offline
Airplane mode, subway, cabin — the assistant still answers instantly.
ChatGPT alternative offline
The ChatGPT alternative that works offline.
A full chat assistant on your device. In airplane mode, on a train, anywhere — no cloud required.
Built for offline
Everything chat needs. None of the cloud.
Chat, voice, and image input — running on the chip in your hand.
Familiar chat UX
Threads, search, pin, rename. Markdown, code blocks, voice input.
No usage caps
Chat as much as you want. There is no quota to hit.
Why offline matters
Latency, privacy, reliability.
An offline ChatGPT alternative answers in milliseconds because no packet leaves the device. Your prompts cannot be logged, sold, or fed back into a training set. And the assistant keeps working when your connection does not — on a flight, in a tunnel, in a hospital, or simply on a flaky café Wi-Fi.
