How to choose a Grammarly alternative

  • Start from the task. Write down the two or three jobs you use Grammarly for and test each alternative on exactly those jobs.
  • Check the pricing model. Free and freemium plans are good for testing; usage limits matter more than the headline price.
  • Look at integrations. A tool that plugs into apps you already use often saves more time than a slightly better model.
  • Read the terms. If you publish or sell what you create, confirm commercial use and data handling in each tool's terms.
