What is Wordtune?
Wordtune is an AI-powered writing and reading assistant developed by AI21 Labs. Its central function is rewriting: you select a sentence and receive several alternative versions, which can be made shorter, longer, more formal or more casual. A grammar checker flags spelling and grammatical mistakes and proposes corrections, while generative commands continue a paragraph, explain a point further, add a conclusion or offer an opposing view. The summariser condenses documents, articles, web pages and YouTube videos. Wordtune writes only in English, but it can translate into English from languages such as Spanish, French, German, Portuguese, Russian, Arabic, Hebrew, Hindi, Korean and Mandarin. It is available on the web, as Chrome and Microsoft Edge extensions and on iOS. Plans consist of a free Basic tier with daily limits and two paid tiers, Advanced and Unlimited, each with a three-day trial.
