01 — The core difference

Siri runs the phone. Acti runs your typing.

Siri is the operating system's voice assistant: set timers, call people, open apps, answer quick questions, control device settings. It's built around spoken commands to your phone.

Acti is an agentic keyboard. It works where you write — messages, email, notes, browsers — and acts on the text in front of you: drafting a reply, creating a meeting link, translating, or running an Act. It connects to apps like Gmail, Slack, Notion and Calendar, and you can build your own Acts.

Device commands vs. getting your typing done

Use Siri for hands-free device control — timers, calls, navigation, quick facts.

Use Acti when you're writing and want the task finished in the app — draft the reply, make the link, translate, run a custom Act — with your connected accounts.

The verdict
Siri commands your phone; Acti commands your keyboard. Acti is the world's first agentic keyboard — the agent that acts on what you type, in any app.
