Sessions-AI
On-device private AI chat sessions
Chat with AI that never leaves your device. Sessions-AI runs powerful language models locally—your conversations stay private and you stay in control.
Private by design
On-device only. No cloud servers. No account required. Your conversations never leave your iPhone, iPad, or Mac.
Chat your way
Create as many chats as you like. Attach files for context. Each conversation saves as a document you can view in the Files app.
Choose your model
Pick from a catalog of open language models. Download only what you need. Tune creativity, length, and behavior in Settings.
Knowledge base
Add your own documents. Sessions-AI searches them locally and grounds answers in your content—all on device. No uploads.
Built-in tools
Calculator, unit conversion, optional web search, calendar, reminders, and more—without sending your data to external services.
100% on-device
No data collection. No account required. No telemetry. No analytics. Your chats, knowledge base, and model data stay on your device.
Available on the App Store
