Mobile platform for user-built AI chat bots and companions
Chai is a consumer platform built around conversational bots rather than one central assistant. Users create characters with their own personalities and opening lines, publish them, and chat with bots made by others; the catalogue spans roleplay, companionship, games and casual entertainment. It runs mainly as a mobile app, with a subscription that raises message limits and unlocks stronger models. The differentiator is the community layer: the interesting part is not a single model but the library of bots and the prompt craft people put into them, plus the tooling the company provides for creators.
