## What is QUIET Ai?

Chat with AI that never leaves your phone.

QUIET Ai runs open models — Gemma, Qwen, Llama, Phi, Mistral, DeepSeek — directly on your iPhone or iPad. No account. Your chats never leave the device. Turn on Airplane Mode and it still works.

ASK YOUR OWN DOCUMENTS
Add PDFs, notes and textbooks to the Vault. Ask a question and QUIET Ai finds the passages that answer it and shows you the source — document and page — so you can check it. Your books never leave the device.

CONVERSATIONS THAT DON'T DEAD-END
Most on-device AI stops with "maximum length reached, start a new chat." QUIET Ai summarises the earlier part of a long conversation and keeps going.

IT KNOWS WHAT YOUR PHONE CAN RUN
Before you download anything, QUIET Ai reads your chip and memory and tells you what will actually run — and how fast. No 4 GB download that won't load.

@ TO BRING THINGS IN
Type @ in any chat to pull in a document, an earlier conversation, or your calendar and reminders — read on the device, never uploaded.

REMEMBERS SO YOU DON'T REPEAT
Keep a short set of notes — your work, your preferences, your house style — and every chat starts already knowing.

PRIVATE IN A WAY YOU CAN CHECK
Every network request goes through one gate in the app. Your chats, documents and notes are never sent anywhere. Settings shows you what's open right now.

ANONYMOUS ANALYTICS — OFF UNLESS YOU TURN IT ON
To help improve the app, you can turn on "Share anonymous usage" in Settings › Privacy. QUIET Ai then sends anonymous counts — which features get used, how fast replies run, crash reports. Never your chats, documents, notes, photos, or anything personal. No account, no advertising ID, no tracking, and you can turn it off at any time.

ALSO
• Any public GGUF model from Hugging Face — free, not a paid tier
• Import a GGUF you already have, from Files or iCloud Drive
• Ask QUIET from Siri, Shortcuts or the Action button
• A dot marks chats with a reply you haven't read yet
• Eight app icons to choose from
• In 12 languages
• Personas: Writer, Coach, Translator, Precise, Natural
• Chats you can mark "don't keep" — deleted when you leave them
• Preview HTML, SVG, Markdown and React that a model writes
• Face ID lock, encrypted backups, full export
• Pause, resume and restart downloads in the background

QUIET Ai Pro
Unlimited Vault documents, unlimited models and personas, and encrypted iCloud Drive backups. Monthly, yearly, or one payment forever. The free tier keeps 3 models and 2 documents, and nothing in the chat is held back.

Subscription: QUIET Ai Pro — monthly or yearly, auto-renewing. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
