About Character.ai
Character.ai is a generative AI chatbot platform founded in 2021 by former Google researchers Noam Shazeer and Daniel De Freitas. It allows users to engage in open-ended conversations with customizable AI characters, ranging from historical figures and fictional personas to entirely user-created characters. The platform leverages proprietary large language models optimized for conversational engagement, enabling highly personalized and contextually aware interactions that prioritize emotional resonance and character consistency over general-purpose tasks. Character.ai operates as a full-stack AI company, controlling its entire model architecture, inference stack, and product infrastructure to optimize for global scalability—currently serving over 20,000 queries per second with an average message generation time of 12.5 seconds. The platform emphasizes user-generated content, with over 200 million community-created characters accessible across web and mobile applications. Character.ai serves a diverse user base, with 54% of users aged 18-24 as of August 2024, and 80% accessing the platform via mobile. The company raised $193 million in total funding, achieving unicorn status at $1 billion valuation in March 2023 following its $150 million Series A round led by Andreessen Horowitz.
