Private on-device AI — summarize, translate, rewrite, even on Airplane Mode. 30 free questions a day. One-time $9.99 unlocks unlimited + Share Extension. No account.

Quiet — Offline AI Assistant

A private AI assistant that runs entirely on your iPhone or iPad using Apple Intelligence. No accounts. No API keys. No subscription. It works the second you open it — even on Airplane Mode — because there's no multi-gigabyte model to download.

The only AI that works on Airplane Mode

Other on-device AI apps make you download a 1–3 GB model before you can ask a single question. Quiet doesn't. It uses Apple Intelligence, which is already on your device, so it works instantly — with zero outgoing network calls. No internet. No account. No data leaves your iPhone.

Free, with a generous daily allowance

Every day you get 30 on-device questions, free — no account, no sign-up. Run out, or want the extras? Quiet Pro is a one-time $9.99 (no subscription) that removes the daily cap and unlocks Quiet everywhere.

What you can do

• Chat with an on-device assistant for writing, editing, summarizing, translation, brainstorming, and code. • 12 one-tap prompt templates: improve writing, summarize, translate, make formal/friendly, brainstorm, outline, critique, explain code, action items, and more. • Edit and resend any message — fix a prompt without starting the chat over. • Regenerate any reply, copy, star, and search conversations. • Per-chat custom system prompt, temperature, and output length. • Send to Quiet from any app: summarize, translate, or rewrite selected text on-device (Pro). • Home Screen and Lock Screen widget to jump straight into a chat. • Siri Shortcut: "Ask Quiet".

Privacy that holds up to a code audit

• Zero outgoing HTTP requests at runtime, apart from Apple-mediated services (App Store only). • No third-party AI provider is called. We don't talk to OpenAI, Anthropic, or Google. • No third-party SDKs. No analytics. No tracking. • Conversations live in a SwiftData store with iOS file protection. • You can erase every chat in one tap from Settings.
