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.
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.
