How to fix or rewrite text anywhere

Select text in any app, call Koi and say what to do with it. The changed words are highlighted, and ⌘Z takes it back.

By Irakli, founder ·

How to do it

  1. Select the text, in Mail, Slack, a browser or anywhere you can type.
  2. Tap Fn + ⌘ and say what you want: "fix the grammar", "make it shorter", "reply that I'll be late".
  3. Koi writes it in place and highlights what changed.
  4. Don't like it? Press ⌘Z.

Worth knowing

  • In a Koi document it can do more: write at the cursor, add a summary, turn lines into headings or lists.
  • Writing for you is a switch in Settings, Koi.
