Wordtune
An AI-powered writing assistant that helps you rewrite, clarify, and improve text while preserving your voice.
What is Wordtune?
Wordtune, launched in October 2020 by AI21 Labs of Israel, is designed as a meaning-aware rewriting and paraphrasing assistant rather than a traditional grammar checker. Users select text they’ve already written and receive multiple stylistically varied rewrites that maintain original meaning, while enabling tone (formal, casual), length, clarity, and fluency adjustments. Over time the platform expanded with features like summarization (Wordtune Read in 2021) and generative sentence enhancements (Wordtune Spices in 2023), positioning itself as a co-writing companion accessible via browser extensions and apps.
