01 — The core difference

Grammarly edits your words. Acti acts on them.

Grammarly is a writing assistant: it checks grammar, spelling, clarity and tone, and suggests rewrites. It's excellent at making the text you write cleaner and more confident.

Acti is a different category — an agentic keyboard. It still helps you write, but it carries an agent that completes the action behind your words: drafting and sending a reply, creating a meeting link, translating, or running a Skill, right inside any app. The output isn't a better sentence; it's a finished result.
