Your AI, your key, your files
An AI assistant for iPhone. Bring an API key from the AI provider you already use, and the app talks to it directly from your phone. It is in testing now and coming to the App Store.
what it does
Any model
Claude, GPT, DeepSeek, open models through OpenRouter or DeepInfra, a RunPod endpoint, or a model on your own computer.
Web and research
Searches the web, reads full pages, and writes reports with numbered sources.
Files and PDFs
Writes files and PDFs into the Files app, and reads the folders you grant it.
Memories
Keeps what you tell it in a list you can edit, turn off or delete.
Talk
Spoken conversations you can interrupt. Everything said is added to the chat.
Pictures
Makes and edits pictures with the image service you choose.
SSH terminal
Works in a shell on your own machine, and asks before each command unless you let it run freely.

Stock reports with a verdict, a scorecard, the bull and bear case and the valuation behind them. For information only.
Free mode
On iPhones with Apple Intelligence, chat with Apple's on-device model with no key, even offline.
your data
Private by design
- Your keys live in the iPhone keychain.
- There is no account to create.
- Your messages go to the provider you picked, not through us.
- No analytics, no tracking, nothing sent to us.
what you need
Before you start
- An iPhone with iOS 18 or later.
- An API key from an AI provider, or your own server. You pay the provider directly.
- Or an iPhone with Apple Intelligence, for free mode.
