Style and grammar checks for long drafts
ProWritingAid reports on a whole manuscript rather than a sentence, with checks for pacing, repeated phrasing, sticky sentences and dialogue tags that Grammarly does not attempt. The reports take a while to read and are worth it once. Free accounts are limited to 500 words at a time, which rules out the long-document work the tool is best at.
Paraphrasing and grammar checks in one place
QuillBot started as a paraphraser and grew a grammar checker, a summariser, a citation generator and a plagiarism check around it. Students are the core audience and the pricing says so, but the rewriting modes are the fastest way to loosen a paragraph that came out stiff. The free tier caps how much text each tool will take at once rather than how often you use it.
Our note
Against Grammarly this is the cheaper option and the better rewriter; Grammarly is the better proofreader and has the wider integrations. If the problem is that a sentence reads badly rather than that it is wrong, this is the one to try.
