Chai, founded by Chai Research in 2021, centers its entire product around user-created chatbot personas rather than one general assistant: anyone can build and publish a character, and a public leaderboard ranks the most popular ones by engagement, turning bot creation into a visible, competitive activity rather than a private hobby.
That marketplace structure, mobile-app-first and skewing toward a younger, roleplay-oriented audience, has built a large and active community around discovering and chatting with community-made characters rather than a single default assistant persona. Content policies here run more permissive than mainstream general-purpose chatbots, within the platform's own stated limits.
A free tier covers standard chatting, and paid plans start around $14 a month for faster responses and more messages. For someone specifically interested in browsing and chatting with a wide variety of community-created characters, ranked by what's actually popular, rather than a single polished assistant, Chai's leaderboard-driven marketplace model is built for that exact use case.
