Offline AI - Private Chat

Run powerful AI models directly on your iPhone — no internet required, no data ever leaves your device.

PRIVATE BY DESIGN
Every response is generated on your device using Apple's
Metal GPU. No API keys. No cloud. No tracking. No account.

ASK ACROSS YOUR DOCUMENTS
Save contracts, manuals or notes to your library, then ask
about them from any chat. The passages that answer your
question are found for you, so a long PDF no longer has to
be cut short. Every answer shows which file it came from.

CREATE IMAGES
Describe a picture and it's generated on your device.
Nothing you type or make is uploaded.

SEE AND SPEAK
Vision models read text in photos and describe what they
see. Voice mode reads replies aloud, hands-free.

BROWSE & DOWNLOAD MODELS
Explore curated categories — Reasoning, Coding, General and
Creative — filtered to fit your device's RAM. Search
HuggingFace live to find any model.

CHAT MODES & PERSONAS
Seven response modes — LaTeX, Code, Concise, Step-by-step,
ELI5, Formal and Email Reply. Give your AI a custom Persona
with a name, icon and system prompt.

WEB SEARCH
Research Mode searches the web before responding, so any
model can answer about current events. Off by default.

STAY INFORMED
The Discover tab surfaces the latest AI news, updated
through the day.

OPTIMIZED FOR IPHONE
Best results on iPhone 15 Pro and later with 8GB RAM.

Pro unlocks voice mode, model arena, vision models and
image generation. Subscriptions renew automatically unless
cancelled at least 24 hours before the end of the period.
