Superhuman acquires AI detection startup GPTZero

Superhuman has acquired GPTZero, a startup known for tools that detect AI-generated writing. The deal adds AI detection capabilities to a product ecosystem that already overlaps with Grammarly’s writing-assistance tools.

The acquisition reflects growing demand for trust and provenance features as generative AI becomes embedded in everyday writing workflows. Detection tools may become a standard layer in productivity software, especially for education, workplace communications, and content integrity.
