About AI writing assistants
Writing assistants cover different jobs. Proofreaders such as Grammarly and LanguageTool check text in the apps where people already write. Rewriting tools such as Wordtune offer paraphrase and tone options, and editors such as ProWritingAid add reports and story tools for long projects. Sudowrite and Jasper use AI for drafting, aimed at fiction writers and marketing teams.
Free access varies. Grammarly, LanguageTool, Wordtune and ProWritingAid all list free plans. Sudowrite and Jasper offer trials but no free plan. Paid prices range from about $5 a month for Wordtune's Advanced tier billed annually to $69 a seat a month for Jasper's Pro plan, so the job you need decides the right tier more than the headline price.
Scores are editorial judgments against the criteria. The quality of AI output depends on the text and the model, so the ranking leans on features, limits and terms that can be checked on each vendor's pages.
