Tacet: Offline Document AI

Tacet is an AI assistant for your documents that runs entirely on your iPhone. REAL DOCUMENT WORK Hand it a spreadsheet and get one back with live =SUM() formulas, not frozen numbers. It reads Word, PDF and CSV, summarizes them on the device, and writes new documents from your notes. NOTHING LEAVES WITHOUT YOUR OK The model runs on-device with Apple Intelligence. There is no cloud and no account. If a task ever needs the network, Tacet first shows you the exact text it would send, and waits. WORKS OFFLINE Chats, notes and files live in your phone's storage. Tacet works in airplane mode. HONEST MATH Arithmetic is computed in code, never guessed. Every step is shown as a visible chip, so you see what it did rather than taking its word. YOUR DAY, ON YOUR TERMS Calendar, reminders and contacts, asked for only at the moment a task needs them. TEACH IT YOUR OWN SKILLS Documents, calculation, calendar, reminders and search are built in. Write your own rules on top, and connect your own MCP server or SearXNG search if you want to. PRIVATE BY ARCHITECTURE, NOT BY POLICY No account, no analytics, no tracking. Keys for your own servers stay in the Keychain. Requires an iPhone with Apple Intelligence. Tacet, Latin for "it is silent."
