QuillBot
A paraphraser, summarizer, and grammar checker. Legitimate on a sentence you wrote and cannot hear anymore. It is also an easy way to launder someone else's wording, which is not a writing practice this directory recommends. Summaries of your own research notes are the kinder use.
Best for
Restating your own sentences, or summarizing source notes you are about to rewrite in your voice.

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.
