ProWritingAid
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.
QuillBot
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.
Why people weigh these two
- QuillBot instead of ProWritingAid
- QuillBot pairs grammar checking with a paraphraser to loosen a stiff paragraph, a sentence-level tool rather than the whole-manuscript pacing reports ProWritingAid runs.
- ProWritingAid instead of QuillBot
- ProWritingAid reports on pacing and repetition across a whole manuscript, a longer unit of text than QuillBot's per-use cap is built to take at once.
Which one should you pick
Pick ProWritingAid for editing long drafts, particularly fiction, where structural feedback across a whole manuscript matters more than sentence-level rewriting. Premium is $10 a month billed yearly, and the free plan's 500-word limit rules out the long-document reports that are the actual point of the tool.
Pick QuillBot if the problem is a paragraph that reads badly rather than a manuscript that needs structural notes, or if a citation generator and plagiarism check on the same bill matter. Premium is $8.33 a month billed annually, cheaper than ProWritingAid, though it is built for students first, so a marketer will find features they never touch.
Common questions
- Which is cheaper, ProWritingAid or QuillBot?
- QuillBot, at $8.33 a month billed annually against ProWritingAid's $10. Both have free tiers with word limits rather than a time-based trial.
- Does QuillBot give structural feedback on a whole manuscript like ProWritingAid does?
- No, that is not part of what QuillBot offers; its rewriting modes work sentence by sentence or paragraph by paragraph. ProWritingAid's manuscript-wide reports on pacing and repeated phrasing are its specific differentiator.
- Does ProWritingAid include a plagiarism checker like QuillBot's?
- That is not described among ProWritingAid's features. QuillBot bundles a plagiarism checker into its Premium plan alongside the grammar checker, summariser and citation generator.
- Which is better for a creator writing short captions and posts?
- By ProWritingAid's own admission, Grammarly serves that better than either of these two. Between ProWritingAid and QuillBot specifically, QuillBot's rewriting modes are the faster way to loosen a stiff paragraph.
