How to choose editing software
Line edits or the whole story?
Most of these tools work on sentences: grammar, spelling, passive voice, repeated words, readability. Grammarly, LanguageTool and Hemingway Editor are in that group. A few read the book as a story. AutoCrit and ProWritingAid add fiction reports on pacing and dialogue, Fictionary looks at scenes and structure, and Marlowe writes a report on a finished manuscript. If your draft has plot problems, a grammar checker will not find them.
Can it take a whole book?
A novel is several hundred thousand characters long. LanguageTool and Slick Write state limits below that, so you would check a book chapter by chapter. ProWritingAid, AutoCrit, Fictionary, Marlowe and PerfectIt say they handle a full manuscript.
Where does it work?
If you draft in Word, Google Docs or Scrivener, a tool that works inside that app saves copying text back and forth. Grammarly and ProWritingAid run as browser extensions and desktop apps; PerfectIt is a Word add-in for Windows and Mac. AutoCrit, Fictionary and Marlowe work on files you upload.
What happens to your manuscript?
Grammarly’s own trust page says your text is used to improve its models unless you opt out. ProWritingAid, AutoCrit, LanguageTool and others state that they do not train on it. The product pages give the wording and the source.
None of these replaces an editor’s judgement; our guide to copy editing vs proofreading explains what a human still catches. For a quick check of one chapter, our free readability checker flags long sentences, passive voice and adverbs without an account, and ProWritingAid vs Grammarly compares the two most searched tools side by side.
How the BookBird Author Score works
In editing & grammar, a product earns up to 50 points for the author jobs its vendor’s pages confirm (grammar and spelling, style reports, fiction reports, handles a whole manuscript, works in Word, Google Docs or Scrivener, custom dictionary or style rules and your text is not used for training), 25 for what a year costs and 25 for how many people in the US search for it by name. The formula, and what it leaves out, is on how we score software.

Questions
Is there free editing software for authors?
Grammarly, ProWritingAid, AutoCrit, LanguageTool, Hemingway and Marlowe have free plans, and Slick Write is free. The free plans limit how much text or which reports you get; each product page lists the plans.
Is Grammarly good for books?
It checks grammar, spelling and tone across apps and handles a long document, but it has no fiction reports, and its own pages say your text is used to train its models unless you opt out.
