Open source conversational chatbot

[Vadorequest]

Hi @JStumpp and thanks for this curated list.

I'm looking for a conversational chatbot that would be open source, without machine learning/deep learning complexities.

There are two parts that are of interest to me:

• Builder: A UI that helps building the conversation (logic jumps, messages, actions, response types, etc.) and eventually generates a JSON schema
• Conversation: A UI (chatbot) generated based on a given schema specification (where the end-user can interact with the bot, answer, pick choices, etc.) and eventually yields the conversation context (that includes all given answers, etc.)

Have you heard of anything similar?
