On the heels of raising a big round of funding at a $1 billion valuation last week, DeepL is taking the wraps off a new language product, the first extension for a startup that made its name from its popular AI-based translation tools.

Write is a new tool that fixes your writing — catching grammar and punctuation mistakes, offering suggestions for clarity and more creative phrasing, and (soon) giving you the option to change your tone. Write is based on the same neural network that powers DeepL’s translator, and significantly, it is another step ahead in how artificial intelligence technologies, specifically those in natural language processing, are being used to alter how humans are communicating with each other, a big theme at the moment.
