Hi Maya,

Fixed as you type. Obvious typos are corrected when you finish the word. Undo is one click.

  • Fixed as you type. Obvious typos are corrected when you finish the word. Undo is one click.
  • Rewrite in a tone. Select text, press ⌃⌥R and pick Improve, Shorter, Formal, Friendly or Confident.
  • Hear how it sounds. A small label tells you when a message reads blunt, and fixes it in one click.
  • Write in Chinese, send English. Press ⌃⌥T. The English is ready by the time you stop typing.
  • Finish sentences with Tab. A grey suggestion runs ahead of your cursor. It is generated on your Mac.

Works where you already write.
No new editor, no copy and paste.
