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.
