Put a full-featured AI assistant in your pocket—without sending a single word to any outside cloud. LLM Pigeon works together with LLM Pigeon Server on your Mac. • Type a message on your iPhone. • The text is stored inside your private iCloud files. • Your Mac picks it up, runs the large-language model locally, writes the reply, and CloudKit delivers the answer back to the phone. Why you’ll love it • 100 % privacy: messages never leave your own iCloud container; no analytics, no ads, no accounts. You can optionally add a search-engine API. • Real LLMs: choose from a set of built-in models or point the server at LM Studio or Ollama to swap in any model you prefer. How it works 1. Install LLM Pigeon Server (free) on a Mac that’s signed in with the same iCloud account. 2. Download the models you want and, if you’d like web search, enter a Serper API key. 3. Start a new chat in the iOS app. 4. Receive answers in seconds, even on hotel Wi-Fi. Zero data collection • No personal information • No usage analytics • No crash logs—everything stays on your devices • If you enable web search, only the queries your LLM generates are sent to Serper.
