Edith vs editGPT: A Proofreader, or a Whole-Book 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. Because it lives inside ChatGPT and plugs into Word and Google Docs, it is a convenient way to clean up a draft wherever you already write.

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.

Because editGPT runs on ChatGPT, it inherits how ChatGPT works, including the limit on how much text it can hold in mind at once. It proofreads the passage in front of it, not your whole novel as one continuous story.

That is fine for grammar, which is local. It is not enough for the things that need the whole book in view: a subplot dropped in chapter three, a detail in chapter twenty that contradicts chapter two. Edith reads your entire manuscript, up to 150,000 words, before she says a word, and re-checks the book for consistency each time you revise, so a fix in one chapter does not quietly break another.

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. 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.

editGPT is a subscription, with a free tier and paid plans from a few dollars a month up to around $100 for unlimited words and team features. 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.
