SillyTavern
Frontend for power users of AI roleplay and creative writing
About SillyTavern
SillyTavern is a free, open-source frontend interface for interacting with AI language models, purpose-built for roleplay, creative writing, and character-driven conversations. It acts as a sophisticated UI layer that connects to multiple AI backends — including OpenAI, Claude, local models via KoboldAI or Ollama, and many others — while providing rich tools like character cards, world info lorebooks, group chats with multiple AI personas, and an active extensions ecosystem for TTS, image generation, and more.
