Airplane mode, subway, cabin — the assistant still answers instantly.
A full chat assistant on your device. In airplane mode, on a train, anywhere — no cloud required.
Chat, voice, and image input — running on the chip in your hand.
Airplane mode, subway, cabin — the assistant still answers instantly.
Threads, search, pin, rename. Markdown, code blocks, voice input.

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.
