RasaHQ/rasa
💬 Open source machine learning framework to automate text- and voice-based conversations: NLU, dialogue management, connect to Slack, Facebook, and more - Create chatbots and voice assistants
Built on transformer-based NLU with intent classification and entity extraction, Rasa uses a dialogue state machine to manage multi-turn conversations with explicit action policies rather than pure end-to-end learning. The framework decouples natural language understanding from dialogue management, allowing developers to define conversation flows through YAML configuration and custom Python actions while maintaining full control over bot behavior and integrations.
