What is Private LLM?

Private LLM is a local and private AI chat app for iPhone, iPad, and Mac. It runs open-source large language models entirely on-device, ensuring conversations never leave the device and no internet is required after the initial model download. The app emphasizes privacy with no cloud, no tracking, and no logins, and offers advanced quantization methods like OmniQuant and GPTQ for high-quality output.

How to use Private LLM?

Download Private LLM from the App Store, then browse and select from 140+ local AI models based on your device and use case. After downloading a model, you can chat offline, use Siri and Apple Shortcuts to build workflows, and on macOS, select text in any app to rewrite, summarize, or correct it via right-click.
