Tacet: Offline Document AI
Excel, Word and PDF on device
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
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."
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• A greeting gets a greeting. Say hello and Tacet answers instead of starting a search.
• The language router behaves the same in all nine languages, and no longer fires on a word that merely sits inside another.
• Connections: reach a connected server without the word "server", and see when a tool actually ran.
• Approval now says what the turn read, and warns when a call would change something on the server.
• No row in the Permissions screen is a dead end any more.
• A date written without a year resolves correctly whatever language your device is in.
• Search no longer spends the time budget that reading the page needs.
• Reply filtering: an unfinished tool call reaches neither you nor the answer beside it.
