Company Background & Positioning
Founded in 2021 by ex-Google AI experts Noam Shazeer (co-inventor of Transformers) and Daniel De Freitas (leader of LaMDA development), Character.AI focuses on building a general artificial intelligence (AGI)-powered personalized dialogue platform. After its $2.5 billion acquisition by Google in 2024, the core team joined Google Gemini AI while maintaining independent operations. With the mission “Making AI Humanity’s Creative Partner,” the company reshapes human-AI interaction through user-generated content (UGC) ecosystems and multi-modal technologies.
