AI rewriting tool that rephrases sentences for clarity, tone, and fluency.

How it works
The tool is aimed at non-native English speakers, students, and professionals who know what they want to say but want it to sound better. Its strength is sentence-level rewriting rather than drafting whole articles: you write the first version, Wordtune polishes it. The tone controls let you shift a message from casual to formal in one click, which is handy for work emails.
Important status note: AI21 Labs stopped active development of Wordtune in April 2025 and the product is now in maintenance mode, so do not expect new features. The free plan gives 10 rewrites a day, and paid plans start at $9.99 per month on annual billing. It remains a solid rewriting tool, but buyers should know its future is limited.
