NLP is the Next
AI Frontier

We are at the start of a revolution in Natural Language Processing (NLP), or the ability of machines to understand and generate natural text. It’s no coincidence that language is a unique human ability, so making significant progress in NLP calls for considerable scientific and engineering innovations.

At AI21 we aim to lead this revolution. And if we succeed, we'll have turned machines into the ultimate thought partners.

Reading and Writing

We believe both writing and reading can be radically transformed by making them AI-first experiences. Machines should work alongside humans and empower them to be better versions of their writing and reading selves.

Your thoughts
in words

AI21's premier product is a writing companion tool that helps you rephrase your writing to say exactly what you mean.

We believe that pattern recognition at scale - of the sort offered by current deep language models - is necessary but not sufficient to achieve our goals. We’re building enriched models that understand context and semantics at unprecedented levels.
