What is Wordtune?
Wordtune is an AI rewriting and editing tool that improves your existing writing rather than generating from scratch. It suggests alternative phrasings, adjusts tone from casual to formal, and expands or shortens sentences on demand. The Chrome extension makes it available anywhere you write online, from Gmail to Google Docs to social media. It is developed by AI21 Labs.
