The Technology Behind Wordtune

Wordtune was built by AI21 Labs, founded in 2018 by AI luminaries. Our goal is to revolutionize the way we read and write. We design advanced AI tools and language models that understand the context and semantics of written text. These models are what set Wordtune apart as the first AI-based writing companion, moving far beyond grammar and spelling fixes to help you put your own thoughts into written words.
