What is Wordtune?
Wordtune is an AI writing and reading assistant that rewrites sentences, changes tone and adjusts length so your message reads the way you intend. It also checks grammar and spelling, continues drafts and summarizes long documents, web pages and YouTube videos. Wordtune is built by AI21 Labs and is popular with professionals, students and non-native English writers.
Wordtune works as a Chrome and Edge extension, a web editor and an iOS app. It runs in Google Docs, Gmail, Slack, LinkedIn, Outlook on the web and WhatsApp Web. Newer tools include a Humanize AI feature that refines AI-generated text and Smart Translate, which turns text in languages such as Spanish or Hindi into polished English.

Grammar and spelling
Unlimited corrections on every plan, including the free one. Basic corrections never count against your rewrite limit.

Humanize AI
Makes AI-generated drafts read more naturally. This feature is helpful when an AI draft sounds stiff or generic.
