Chai Research is an advanced AI conversational platform and research hub that enables millions of users and creators to interact with, build, and customize chat-based AI agents. The company develops and hosts large language models designed for long-context, social, and engaging conversations — ideal for entertainment, companionship, roleplay, and interactive dialogue experiences. Users can explore a wide variety of AI characters crafted by others or build their own chatbots with unique personalities and behaviors, then share them within the community.

Chai AI emphasizes research-driven model improvements using techniques like reinforcement learning with human feedback (RLHF) and low-rank adaptations to enhance engagement and conversational quality. It also offers developer resources and API access, enabling integration of its conversational AI capabilities into other applications and projects. While primarily known for its mobile and web chat interfaces where users engage directly with AI characters, the platform stands out for its creator ecosystem and focus on social AI interactions that feel dynamic and personal rather than purely task-oriented.
