Edith vs editGPT: A Proofreader, or a Whole-Book Editor?
editGPT is a popular AI proofreader that shows its corrections as tracked changes, in its own editor and in Word, and for tidying grammar and style it is genuinely handy. The question is what happens when you want more than tidy prose: feedback on whether the story itself works. Here is an honest look at what editGPT does, and where Edith is built differently.

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
editGPT is an AI proofreading and line-editing tool. It checks grammar, spelling, punctuation, style, and tone, and shows its edits as tracked changes you accept or reject, in a standalone editor that takes up to 200,000 words at once and round-trips Word files, with a browser extension for the ChatGPT site. It is fast, cheap, works in more than 80 languages, and is a solid last-mile polish for any kind of writing.
Edith does a different job. She reads your entire manuscript as one story, writes you an editorial letter on what is working and what is not, and takes you through the whole edit, developmental to proofreading, one note at a time. If you want your grammar and style cleaned up, editGPT is good at that. If you want an editor who has read your book and will tell you whether it holds together, that is what Edith is for.

A proofreader, or a developmental editor
editGPT's job is the polish. It scans your text for grammar, spelling, punctuation, and awkward phrasing, and it can shift the tone to be more formal, casual, concise, or clear. Its editor imports a Word file, marks the changes, and exports it back with the tracked changes intact, which is a convenient way to clean up a finished draft. We go through the editor, the five edit levels and the prices in our editGPT review.
Proofreading is the last mile of an edit, though, not the whole road. It tidies the sentences you have; it does not tell you the second act sags, or that a character's motivation does not track, or that a thread you set up early never pays off. Edith is built around that developmental reading. She takes in the whole manuscript first, then tells you what the story is doing well and what is holding it back, and why, long before you get to polishing the prose.
Proofreading and developmental editing sit at opposite ends of the same sequence, which we explain in what kind of editing does your book need and what order to edit your novel.

It takes the whole document, and reads none of the story
editGPT's book-editor page says its editor handles a document of up to 200,000 words and returns it edited in under a minute. That is a real advance on the pasted-passage workflow of its browser extension, and it means a whole novel goes in at once. What comes out is the same kind of thing: sentences corrected or recast, marked as tracked changes. Nothing in editGPT reads the manuscript as a story or tells you whether it works.
That is fine for grammar, which is local. It is not enough for the things that need the whole book held in mind: a subplot dropped in chapter three, a detail in chapter twenty that contradicts chapter two, a middle that sags. Edith reads your entire manuscript, up to 150,000 words, before she says a word, writes you an editorial letter on the book as a whole, and re-checks the book for consistency each time you revise, so a fix in one chapter does not quietly break another.
Taking a whole file and reading a whole story are different things, and the difference is the subject of editing software that reads the whole manuscript. The general-model limit that the extension inherits from ChatGPT is described in why AI forgets the middle of your book.
It edits your words; Edith leaves them yours
editGPT's whole function is to change your text. It rewrites for correctness and can recast your tone, and it presents each change as a tracked edit you accept or reject. By its own figures, its lightest level changes about 5% of your words and its heaviest about 40%. That accept-or-reject control is a genuinely nice touch, and nothing lands without your yes, but the edits themselves are the model's words offered in place of yours.
Edith never rewrites or generates a word of your prose, at any stage. She leaves notes and suggestions, like a human editor in the margins, and builds a profile of your voice and your characters so the suggestions sound like you. She hands you notes, never new prose, so no word of hers ever ends up in your book.
The difference between a note and a rewrite is the difference between keeping your voice and losing it, as we set out in editing your novel without losing your voice.
One subscription, or one book
editGPT is a subscription: on its home page on 10 October 2026, Pro is $15 a month ($8 a month billed annually) for 500,000 words a month, Elite $25 ($15 annually), and Business $100 ($60 annually) for unlimited words and team seats. Third-party reviews put the free plan at 10,000 words a month; editGPT's own pricing page would not load when we checked. That suits someone proofreading many documents continuously, across emails, posts, and drafts of every kind. Edith is paid once per manuscript, for the full edit, which suits an author who wants one book taken from draft to finished without a meter running. Different shapes for different needs, and some authors will use both: Edith for the developmental edit, a proofreader like editGPT for a quick grammar pass on everything else they write.
