YouBot is a natural language dialog application framework that allows users to build dialog applications that can communicate with users via text or voice in multiple channels. It uses pattern matching and processes to handle natural language conversations. Developers can define patterns and processes to control the dialog flow and integrate external APIs and databases. The system also supports context, input/output filtering, and inter-bot communication.
