How to choose

  1. Decide if you want help fixing your own words (a checker) or someone to draft for you (a writer). They're different tools.
  2. Pick one that works where you write: browser, Word, Google Docs or your email app.
  3. Always read and edit AI drafts. Readers notice generic, robotic writing.
