Wordtune
Wordtune is an AI rewriting, summarizing and grammar assistant built by AI21 Labs. It suggests alternative phrasings and tone changes for English text inside a web editor, browser extensions and an iPhone app. It suits non-native English speakers, students and professionals who want sentence-level help rather than a tool that writes whole documents for them.

What is Wordtune?
Wordtune started as a sentence rewriter and now covers rewriting, summaries, grammar checks and short AI expansions. You highlight text in its editor or in a supported browser and it proposes alternatives; it does not silently rewrite a whole document for you.
Plans compared
- Basic ($0): 10 rewrites and AI suggestions per day, 3 summaries per month, unlimited grammar checks.
- Advanced: 30 rewrites per day, 15 summaries per month, AI recommendations.
- Unlimited: uncapped rewrites and summaries, vocabulary and fluency improvements, premium support.
Business plans exist separately and add SAML SSO and centralized billing.
Limitations
Wordtune is English-first: other languages go in, English comes out. There is no Android app, no Safari extension and no Mac desktop app. Refunds are not offered, only cancellation before the next cycle. The steady stream of updates that marked its early years has dried up, so check that the feature set you need exists today rather than expecting new ones.
