An AI writing companion by AI21 Labs that rewrites sentences, adjusts tone, and summarizes documents from a browser overlay.

Wordtune is an AI paraphrasing app that uses proprietary natural-language models to rewrite text. It analyzes the semantic meaning of your input and generates multiple phrasing variations that keep the original meaning, working as an overlay inside text editors and browsers.

Wordtune is a legitimate tool developed by AI21 Labs with strict data-privacy standards. It encrypts user text in transit and does not use private data to train public models, complying with standard industry security frameworks.
