Chai AI

Builds and chats with personalized AI companions for engaging conversations. CHAI is the leading AI platform, performing research in conversational generative artificial intelligence. Chai focuses on social entertainment with user-created ChatAIs optimized for engagement via RLHF, unlike utility-focused bots like ChatGPT. Users build custom bots using prompts to define personalities, backstories, and traits, with easy editing tools. It offers a free tier with limits and ads, while premium unlocks unlimited messages and advanced features. Voice previews are in beta for premium users, with full synthesis planned but not yet widespread. It uses a permissive approach for creative freedom, relying on community ratings over strict filters. Primarily mobile via apps, with a beta web version available but lacking full features.
