Best Editing and Proofreading Software for Writers

Grammar checkers, style tools and manuscript analysis compared, with prices, platforms and how each one uses AI.

Disclosure.

I built Writing Desk because I was frustrated with apps that were too complicated, too busy, or without the features I needed entirely. I built it for novels, but now use it for everything.

That said, some writing apps are better at certain jobs than others, and whilst I obviously think Writing Desk is the best of the best, I have tried to be impartial in my assessments.

Last updated 11 October 2026. Prices and verdicts reviewed quarterly.

My pick

ProWritingAid for sentence-level reports; Writing Desk for editing built into the writing app

Editing tools come in two kinds. Sentence-level checkers such as ProWritingAid, Grammarly and LanguageTool work inside the tools you already use. Manuscript analysers such as AutoCrit, Fictionary StoryTeller and Marlowe look at structure, pacing and character across a whole draft. My pick depends on where you write, and on a Mac, if you want editing in the app where you draft, it is Writing Desk. I built it, so weigh that.

  • Proofreader beside the manuscript
  • Prose Analysis beside the manuscript
  • Editorial AI review of your draft
  • Every suggestion is yours to accept or reject

Pick something else if you want…

  • Windows, or a life in Word: ProWritingAid, which has the widest set of style reports
  • Sentence-level checks inside the tools you already use: Grammarly or LanguageTool
  • Structure, pacing and character across a whole draft: AutoCrit, Fictionary StoryTeller or Marlowe

Each app is checked against its own pages for platforms, price and AI stance, and prices carry the date I checked them. I have used Google Docs, Word, Scrivener, Ulysses and Obsidian for my own writing; the rest are assessed from vendor pages and published reviews.
