CSML helps chatbot development teams build truly intelligent, maintainable and scalable chatbots, integrated with your favorite apps, on any channel, with full control over your source code.
CSML is both an open-source, domain-specific programming language, and a conversational engine, created by Clevy.io. Its expressive syntax makes it extremely easy to develop complex chatbots, and its processing engine features built-in short and long-term memory, powerful context management, and integrations with other systems through HTTP APIs.
While CSML is a full-blown programming language giving you complete control over the final experience, it is designed to be picked up even by beginners. Thanks to its expressive, descriptive syntax, it takes just a few minutes to develop your first full-featured chatbot.
