What is it?

AI Chatbot Framework is a self-hosted platform for building chatbots in Python. It lets you design natural language conversation scenarios through a web admin dashboard, so you can create and train bot conversations without writing code. The project aims to make AI-powered chatbots accessible to developers who are not AI specialists.

The framework combines several NLU approaches: spaCy word embeddings, ML-based intent recognition and entity extraction, and zero-shot understanding using large language models. It supports multi-turn conversations, API request fulfilment through tool calling, persistent memory and context management, and conversation logs. A knowledge base and FAQ answering feature based on RAG is listed as in development.

The bot can be reached through a REST API or a chat snippet on the web, and Facebook Messenger is supported. Slack and WhatsApp via Twilio are planned. The stack uses FastAPI, MongoDB, React with Next.js, scikit-learn, TensorFlow/Keras, and Docker, with Kubernetes and Helm for deployment.
