Wordtune - AI21 Labs' AI Rewriting Companion for Clearer English Writing

Wordtune is an AI rewriting companion from AI21 Labs that helps non-native English writers say the same thing more clearly. Rather than fixing grammar like a checker, it suggests several rephrasings for each sentence so you can pick the tone that fits. Founded in 2017 and based in Tel Aviv, it works inside Google Docs, Gmail, and any web text field through a Chrome extension.

Core Features

  • Multiple rewrites per sentence, each restructuring meaning while keeping intent, so you compare options side by side.
  • Tone control that shifts a line between casual and formal registers with one toggle.
  • Expand and Shorten that add context or trim filler without losing the point.
  • Spices that drop in examples, statistics, or counterarguments drawn from context.
  • Wordtune Read, a summarizer that condenses long articles and documents into key points.

Best For

  • Non-native English speakers who know what they mean but struggle with natural phrasing.
  • Marketers polishing social posts and client copy under deadline.
  • Editors who want multiple phrasings before committing to one.

Pricing

The Free plan gives 10 rewrites and 3 summaries per day with unlimited grammar correction. The Advanced plan costs $9.99 per month with 30 daily rewrites and full Spices. Unlimited runs $14.99 per month with unrestricted rewrites and priority processing. A Business tier is quoted per seat.

Our Take

Best for sentence-level rewriting where tone matters; the catch is that it is not a grammar checker and will not catch errors, so pair it with one. For ESL writers it is hard to beat at the price.
