Superhuman Acquires AI-Detection Startup GPTZero
Superhuman has acquired GPTZero, a three-year-old AI-detection startup founded as a senior thesis project by Edward Tian. Terms were not disclosed. According to Tian, GPTZero had more than 19 million registered users and reported $30 million in annual recurring revenue. The company raised roughly $13.5 million in total venture funding, including a $3.5 million seed round led by Uncork Capital and a $10 million Series A in June 2024 led by Footwork co-founder Nikhil Basu Trivedi. Superhuman — formed after Grammarly bought the email provider Superhuman and rebranded under that name — already includes an AI detection tool and said it sees value in combining detectors from both products.
Superhuman Go Expands AI Agent Ecosystem with New Partners
Superhuman expanded its Superhuman Go AI agent ecosystem by adding partner-built agents from Box, Gamma, and Wayground, now available in the Superhuman Agent Store. The integrations let Go users access enterprise documents (Box), generate polished presentations (Gamma), and create quizzes or flashcards from on-screen content (Wayground) without switching tools. Superhuman positions Go — launched in October 2025 and built as an open agent platform that works across more than 1 million apps and websites — to close the gap between basic AI tasks and advanced, workflow-integrated assistance. The company says additional partner agents (including Swoop by Prezi) are coming, and highlights combined use cases where multiple agents interoperate to speed tasks like stakeholder presentations, classroom content creation, and project documentation.
