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.
An AI writing partner aimed at novelists
Sudowrite is written for fiction, which is what separates it from the marketing copy generators: it holds characters and plot state, suggests where a scene could go, and rewrites a paragraph in a described voice. Story Bible keeps a long manuscript consistent. Everything runs on credits, so a heavy drafting month costs more than a light one.
