Chai AI - Chat With Millions Of AI Characters Uncensored Anytime

Chai AI hosts over one million community-created AI chatbot characters spanning anime, fantasy, romance, celebrity, and NSFW categories. Users can browse, interact with, or create their own custom characters using the built-in creation tools.

Chai AI offers flexible, user-adjustable content filters that allow NSFW conversations to proceed naturally. Many bots on the platform are community-created with explicit personas, and the moderation is notably more relaxed compared to competitors like Character AI.

Users can build custom AI characters using a no-code creator that supports up to 32,000 words for character definitions. You can set introductions, personality descriptions, backstory, and even add custom voices. Characters can be kept private or published publicly.

Chai AI runs on proprietary in-house LLMs ranging up to 235 billion parameter Mixture-of-Experts models. These are optimised using GRPO and DPO reinforcement learning techniques and trained on billions of user-generated tokens for engagement-focused responses.

Chai AI has very limited memory persistence. The platform does not retain long-term conversation history across sessions, which means bots may forget details from earlier chats. This is a commonly reported limitation among users.
