Wordtune

AI21 Labs

A writing companion that rewrites sentences for tone, clarity and length, with summarization for articles and meeting recordings.

Product preview

Overview

Wordtune focuses on the sentence: it rewrites what you already wrote for tone (casual to formal), length (shorten or expand) and clarity, which makes it a refinement tool rather than a blank-page generator.

Its summarizer extends the same idea to reading — articles, documents and even meeting recordings collapse into key points — and the browser extension brings rewriting into Gmail and every text box you type in.
