Ask about your day, set reminders, turn notes into documents. Tacet lives in your terminal and runs entirely on your computer. No account, no cloud, and nothing you say ever leaves your machine.
The demo above plays by itself, on a loop. The real thing is exactly this simple: you type, Tacet answers.
Copy it, paste it, come back in five minutes: the installer sets up Tacet, fetches the model (one-time, ~2 GB) and starts your first chat.
curl -fsSL https://usetacet.com/install.sh | sh
Already have Rust? cargo install tacet-cli works everywhere, then tacet chat. The model download stays on your disk; nothing else is fetched, ever.
No commands to memorise, you just write what you want in plain language.
"What's on tomorrow?" Tacet reads your calendar, sets reminders and never lets you miss a call.
Ask for a Word document or an Excel sheet and it lands in your folder, ready to send.
Tell it things worth keeping — it takes notes and brings them back exactly when they matter.
Tacet works offline. If a question needs the internet, it asks you first every single time.
"Tacet" is the old musical word for "it stays silent". That's the whole idea.
The intelligence runs on your own machine, not on a server. Unplug the internet, Tacet keeps working.
Nothing to sign up for, nothing to log in to. There is simply no place your conversations get sent to.
Whenever Tacet checks your calendar or writes a file, it shows a small receipt on screen. Nothing happens behind your back.
Ollama, LM Studio and llama.cpp are excellent model runners: pick a model, get a chat window. Tacet sits one level up — a finished assistant, built on the same kind of local models.
| Model runners | Tacet | |
|---|---|---|
| Chat with a local model | ✓ | ✓ |
| No account, no telemetry | ✓ | ✓ |
| Reads your calendar, sets reminders | — | ✓ |
| Turns notes into Word and Excel files | — | ✓ |
| A memory you can see and edit | — | ✓ |
| A receipt on screen for every action | — | ✓ |
| Asks before ever touching the web | — | ✓ |
No shade meant — model runners are great at what they do, and Tacet gladly runs the same open models. The difference is everything wrapped around the model.
