Everything you need.
Nothing you don't.

A powerful AI assistant without the subscription, the account, or the data collection. The way it should be.

01 · PRIVATE

Nothing leaves your phone.

Every message, every photo, every conversation is processed on your device. We don't have servers that see your data because we don't have servers. There's no account, no telemetry, no analytics. The privacy claim is structural, not a promise.

Zero network calls during chat

02 · OFFLINE

Works in airplane mode.

On a flight, in a tunnel, in the middle of nowhere. The model lives on your device, not in a cloud. Download once, use forever, anywhere.

03 · PERMANENT

One payment. Yours forever.

$19.99 once. No subscription. No upsells. No surprise charges. Future updates included. Cancel-friendly because there's nothing to cancel.

04 · POWERFUL

State of the art.

Gemma 4 and Qwen 3.5, the same open-weight models trusted by enterprise teams, running on your phone. With image understanding included.

05 · MULTIMODAL

Add an image. Ask anything.

Snap a photo of a menu, a receipt, a math problem, a plant, and ask about it. Vision runs locally too. Your photos never upload anywhere.

On-device models

open-source models.

Pick the model that fits your device. Switch between them at any time. Each one runs entirely locally.
