After the draft exists
ProWritingAid
A manuscript editor: repeats, pacing, sticky sentences, style, and echoes across a full draft, plus newer generative rewrites. It is opinionated and sometimes wrong, which is still useful if you treat every highlight as a question. Stronger on a finished draft than on a blank page.
Best for
Authors who want a book-length style report after the story is down, fiction or nonfiction.

What it is
ProWritingAid is a writing and editing platform for authors: "Draft Freely, Edit Wisely." It began as a grammar and style checker with in-depth Writing Reports and now spans planning (Story Canvas, Plot Analysis), drafting support (Writing Sessions, Sprints, Creative Nudges), line editing (Grammar Checker, Writing Reports, Rephrase, Sparks), and AI critique (Chapter Critique, Character Analysis, Manuscript Analysis, Virtual Beta Reader, Marketability Analysis). It also runs community events such as Novel November and the Novel Beginnings contest.
Who it's for
- Novelists in revision who want both line-level reports and story-level critique.
- Long-form nonfiction writers who want style reports beyond grammar.
- Writers who like structure and community: challenges, sprints, camps.

Editing
AutoCrit
Fiction editing reports for dialogue, pacing, repetition, and overused phrasing, plus a story analyzer and an AI reader you can steer with instructions. The reports compare your draft with genre tendencies, which is a clue, not a verdict. It will not write the book for you.
Best for Novelists who want genre-aware notes on a complete draft, not a chatbot that continues the scene.
SubscriptionFictionDrafting
Claude
A general assistant that writers often prefer for long passages, tone, and a calmer revision pass. Projects can hold notes and chapters you upload. It is still a chat, not a novel app: continuity across a whole book is only as good as the pages you put in front of it.
Best for Drafting and revision when you want a careful reader more than a plot machine.
FreemiumFiction and nonfictionEditing
DeepL Write
Rewrite suggestions from the company behind DeepL translation. It is aimed at clearer phrasing, not plot. Particularly useful if you draft between languages or want a second wording that is conservative rather than clever. It will happily smooth a sentence that was supposed to be sharp.
Best for Nonfiction clarity, and writers moving between languages who want phrasing help rather than a story engine.
