The second pair of eyes on everything you write
Grammarly catches the mistakes that get noticed in a sponsor email or a video description, and it does it inside whatever box you are typing in rather than in a separate app. The free tier covers spelling, grammar and tone. Rewriting, plagiarism detection and the larger prompt allowance sit behind Pro.
Only on this side
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.
Ratings are the average of reviews readers left. The facts are stated by each tool’s own listing and are not verified by CloutStack. How we make money.
