Best Sentence Rewriter Tools for Mac (2026)
The best sentence rewriter tools in 2026 are Echoo, Wordtune, QuillBot, Grammarly, ProWritingAid, and ChatGPT. Echoo is best for rewriting a selected sentence directly inside any Mac app and assigning different tones to shortcuts; Wordtune is best for quick alternatives, and QuillBot is best for browser-based rewrite modes.
A sentence rewriter should improve clarity or tone without inventing facts. Short inputs make context especially important, so the strongest tools let you specify audience, formality, length, and words that must remain unchanged.
We compared the leading options for sentence-level control and the amount of friction between draft and finished text.
