Assistants for drafting, editing and translating. Includes the general chat models people write with every day plus the specialists that beat them at one narrow job.
The strongest of the chat models at long-form prose and at following an editorial brief without drifting into marketing voice. Handles very long documents in one go, which matters for editing rather than drafting.
The default, and the one with the widest set of bolt-ons: web search, image generation, code execution and custom GPTs. Prose has a recognisable house style you will need to edit out.
Best pick if your writing lives in Docs and Gmail, because the integration is the actual product. The very large context window makes it good at summarising a pile of source material.
Built for novelists, not for blog posts. The Story Bible keeps characters and plot consistent across a full manuscript, which is the thing generic chat models cannot do.
A quiet writing app with AI available only when you ask for it. The right choice if other tools interrupt your thinking with suggestions you did not want.
Still the most reliable everyday proofreader, and it works everywhere you type. The tone and clarity suggestions in the paid tier flatten your voice if you accept all of them.
Deeper reports than Grammarly on pacing, repetition and sentence variety, aimed at people writing books. Slower and more cluttered in exchange.
Highlights long sentences, passive voice and adverbs and nothing else. The free web version is enough to fix most bad business writing in five minutes.
Paraphrasing and summarising with adjustable levels of rewriting. Handy for tightening a paragraph you are too close to, and easy to misuse into bland mush.
Marketing copy at team scale, with brand voice profiles and campaign workflows. Hard to justify for one person now that general chat models do the same drafting.
Has shifted from copywriting toward sales and marketing workflow automation. Consider it when you want repeatable pipelines rather than one-off drafts.
Translation that reads like it was written by a person, especially across European languages. The glossary and document translation features are the reason companies pay for it.
Grounds every answer in the documents you upload and cites them, so it is a research notebook rather than a drafting tool. Excellent for writing from sources you must not misquote.
Mistral assistant, fast and strong in French and other European languages. A reasonable pick if you want an EU-based provider.
Manuscript management with a codex of characters and places, and you plug in your own AI model key. Best for planners who outline before they write.
