CHAI is a consumer platform where anyone can create, publish, and chat with AI characters — a crowdsourced library of 500,000+ personalities spanning roleplay, stories, and companionship. Founded in 2021 by ex-quant William Beauchamp, it runs proprietary models tuned for entertaining, social conversation rather than factual assistance, and reached $70M in annual revenue in 2026 with over a million daily active users.
