Grammarly to acquire Superhuman

Grammarly, best known for its AI-powered writing assistant, plans to acquire the premium email app Superhuman to expand into productivity tools.

The writing tool already revises over 50 million emails weekly across 20+ providers, and the company now wants a dedicated email app to better showcase its AI assistant.

The move also signals something bigger: Grammarly aims to become a multi-product platform powered by AI agents. These could assist users with tasks like writing customer memos or managing support emails, potentially working together within your inbox.

Grammarly believes email is the perfect starting point, since professionals spend over three hours daily checking emails.

After acquiring productivity startup Coda last year, Grammarly is now pushing to compete with OpenAI and Google in the race to build agent-powered tools.
