Key points about the acquisition:

-
Grammarly plans to integrate Superhuman’s AI capabilities to build a network of AI agents that streamline workflows in email and potentially other productivity areas like calendaring and task tracking.
-
This move positions Grammarly to compete with tech giants like Google and Microsoft, which are also embedding AI features in their productivity suites.
Financial details of the acquisition were not disclosed. Superhuman was last valued at $825 million in 2021 and generates about $35 million in annual revenue, while Grammarly serves over 40 million daily users with annual revenue exceeding $700 million.
