Our verdict
Wordtune is an AI writing companion focused on sentence-level rewriting, offering casual/formal tone adjustment, expansion, shortening, and translation. It works as a browser extension and editor plugin. Best for professionals refining their writing tone and clarity. The main caveat is narrower features than Grammarly and less paraphrasing power than QuillBot.

Compare Best AI · Editorial Team
Wordtune focuses on sentence-level rewriting rather than document-wide editing. Highlight a sentence, and Wordtune suggests multiple rewrites — shorter, longer, casual, formal, or in a different language. This approach is more intuitive than QuillBot's document-level paraphrasing for quick refinements.
