Character.ai
Personality-driven AI chatbot
About Character.ai
Character.ai is an AI chatbot platform where users create and interact with AI characters — fictional personas, historical figures, or custom personalities. Founded in 2021 by Noam Shazeer and Daniel De Freitas (both former Google engineers who worked on LaMDA/Bard), Character.ai has built one of the most engaging consumer AI products, with users spending an average of 2 hours per session.
The platform hosts millions of user-created characters and generates over 20,000 messages per second at peak usage. Character.ai's engagement metrics rival social media platforms, suggesting that personality-driven AI interaction may be a more compelling consumer product than general-purpose chatbots.
In 2024, Google licensed Character.ai's technology and hired back co-founders Noam Shazeer and Daniel De Freitas in a deal valued at approximately $2.7 billion. Character.ai continues to operate independently under new leadership.
