What is Wordtune?
Wordtune is an AI writing and reading assistant that rewrites sentences, adjusts tone, fixes grammar and spelling, and summarizes long content. It suggests alternative phrasings in context, can make text more formal or casual, and can shorten or expand sentences.
Beyond rewriting, Wordtune offers "continue writing" generation, paragraph options such as explain, emphasize and conclude, a smart synonym finder, and Smart Translate, which turns text in 10 supported languages into English. It can also summarize articles, webpages, documents and YouTube videos, humanize AI-generated text, and check facts against multiple sources.
Wordtune runs as a web app, as Chrome and Edge extensions, and as an iOS app. It is made by AI21 Labs. It suits students, professionals and non-native English speakers who want help phrasing text. A free plan has daily limits, and paid plans raise or remove those limits.
