Edith vs ProWritingAid: Line Polish, or a Whole-Book Edit?
ProWritingAid and Grammarly are excellent at what they do, and almost every author should clean their prose with a tool like one of them at some point. The thing to be clear about is that line polishing and developmental editing are different jobs. Here is an honest comparison with Edith.

Your first 10,000 words are free: Edith reads your opening and writes you an editorial letter. The whole book, with every point open to discuss, is $15.
The short answer
ProWritingAid and Grammarly are line-and-language tools at heart. They check grammar, clarity, style, overused words, sentence variety, and readability, and they do it very well. ProWritingAid in particular has more than twenty-five reports built for long manuscripts, and now also offers an AI Manuscript Analysis that gives whole-book, story-level feedback as a report.
Edith works at the level of the story rather than the sentence: whether the structure holds, whether characters are consistent, whether the pacing earns its turns. She reads the whole book, writes you an editorial letter, and takes you through the edit, developmental to proofreading, as a conversation, never rewriting your words. Many authors use both: a line tool for polish, Edith for the edit underneath it.

Two different jobs: polishing lines, and editing a story
ProWritingAid and Grammarly are at their best on the sentence. Grammar, clarity, overused words, sentence variety, readability: this is the work of a line and copy pass, and ProWritingAid in particular does it about as well as anything for a full manuscript. That is real value, and it is worth doing.
Developmental editing asks a different question: not whether the sentences are clean, but whether the story works. Where does the structure sag, which character's arc does not pay off, where does the pacing lose the reader. A grammar checker is not built to answer that, and mostly does not try to.
Naming the two jobs properly is most of the decision, which is what what kind of editing does your book need is for. We also reviewed ProWritingAid on its own terms, including what the subscription leaves out, in our ProWritingAid review.
What ProWritingAid's manuscript analysis is, and is not
To be fair, ProWritingAid has moved into story-level territory. Its AI Manuscript Analysis reads a whole manuscript and returns developmental-style feedback on plot, character, theme, pacing, and structure, and ProWritingAid is upfront that it is not meant to replace a human developmental editor.
It arrives as a static report, bought with credits, that you read and act on alone. Edith's developmental edit is the core of the product, not an add-on: an editorial letter, then specific notes you discuss and that adapt to your decisions, with consistency re-checked as you revise. The difference is less whether story feedback exists and more whether it is a report you receive or an edit you work through.
Reading a chapter at a time is a real constraint on story-level feedback, for the reasons in why AI forgets the middle of your book. If you are weighing it against AutoCrit, we compared the two in AutoCrit vs ProWritingAid.
Rewrites, or your words left alone
Both ProWritingAid and Grammarly suggest rewrites of your sentences, and accept them inline. For grammar and clarity that is exactly what you want. Across a whole book, though, taking rewrite after rewrite can slowly sand your voice toward something more generic.
Edith never rewrites or generates your prose. She leaves notes and suggestions, like a human editor in the margins, and builds a profile of your voice so the notes sound like you. No word of hers ever ends up in your book. How that works sentence by sentence is on line editing with Edith, and the correctness pass that follows it on copyediting with Edith.
Accepting every suggestion is how prose gets smoothed into anonymity, the risk we describe in editing your novel without losing your voice.
Where Grammarly fits, and how they pair
Grammarly is grammar, clarity, and tone everywhere you type, with no plot, character, or structure analysis at all, which makes it great for everyday writing and polish but not for editing a novel's story. None of this is a knock: these are strong tools for the job they are built for. The honest workflow is to use a line tool to clean the prose, and Edith to make sure the book underneath it works. ProWritingAid and Grammarly run on subscriptions, with ProWritingAid also offering one-time lifetime plans; Edith is paid once per book, with the full edit included.

Where ProWritingAid is the better choice
ProWritingAid or Grammarly is the better choice when:
- You want the deepest line-level toolkit: grammar, style, overused words, sentence variety, and readability.
- You want suggestions inline in Word, Scrivener, Google Docs, or your browser as you write.
- You would rather pay once for life, which ProWritingAid's lifetime plans allow, for a line tool you will use forever.
- You want polished everyday writing, emails, blurbs, and queries, not just your manuscript, which is Grammarly's strength.
Edith is the better choice when:
- You want to know whether the story works, not just whether the sentences are clean.
- You want a developmental edit you discuss and that adapts, not a static report.
- You want your voice protected, with nothing rewritten for you.
- You want the whole edit, developmental through proofreading, in one place, paid once per book.
The bottom line
ProWritingAid and Grammarly are excellent at the sentence: grammar, style, clarity, and polish. Edith works at the level of the story: structure, character, pacing, and consistency, discussed with you and carried through the whole edit.
Use a line tool to clean the prose. Use Edith to make sure the book underneath it works. Many authors use both.
