About
Wordtune is an AI-powered writing companion developed by AI21 Labs, one of the leading AI research companies. It goes beyond simple grammar checking to fundamentally understand the meaning of what you've written and offer intelligent rewrites that preserve your intent while improving how it's expressed.
The tool offers multiple rewriting options for any selected sentence — letting users pick the phrasing that best fits their voice. It can make text shorter (more concise), longer (more detailed), formal, or casual. Its Spices feature can insert examples, analogies, statistics, and counterarguments to enrich writing on the fly.
Wordtune is especially popular among non-native English speakers who want to write more fluently, professionals crafting high-stakes communications, and content creators who need to produce polished work efficiently. It integrates directly into Google Docs, Gmail, Twitter, LinkedIn, and dozens of other web platforms via its browser extension.
