User reviews

Users appreciate Microsoft Editor for improving spelling and grammar in multiple languages and for being a helpful daily writing aid. It's praised for its comprehensiveness and usefulness to users with varying language proficiency. However, some users report issues such as premium features not activating outside of Edge, malfunctioning on some websites, and subpar formatting. A few users note limited correction scope, and improvements could be made to appearance and compatibility across browsers and platforms.
Pros
  • Helps improve spelling and grammar across multiple languages.
  • Very useful and handy for day-to-day writing and proofreading.
  • Helps users write faster and better with fewer errors.
  • Works well as a comprehensive spell checker, better than default browser tools.
  • Helpful for users with weak language skills or those learning a language.
Cons
  • Premium status not recognized in Chrome and some browsers, only works fully in Edge.
  • Does not work properly on some websites, failing to recognize chat boxes or input areas.
  • Formatting and appearance could be improved for better user experience.
  • Limited functionality noted by some users, such as only pointing out synonyms instead of broader corrections.

Casual, everyday user, often within Claude conversations. In Chrome. Unlike similar grammar/editing utilities, I find Microsoft Editor to be effective without being intrusive. Not perfect, always improving, like it very much. Easy to get used to; has a very light hand.

Muy útil para no perder, ni olvidar al escribir las reglas de la ortografía.

Wake me up when Microsoft fixes this. Editor doesn't register premium status in Chrome or Vivaldi even if you have OneDrive personal. It works fine in Edge, their own product, of course, just not in competing products.
