finally I have seen https://github.com/imartinez/privateGPT working in my local computer, it is kind of a search engine for documents, I was looking for more conversation level bot which can learn from the conversation and start answering accordingly, why am I searching for this, it is about our jira`s, there are some repeatitive tickets, if I can teach a bot to realize those and solutions, it can answer users directly or can tell me which doc to answer. not bad privateGPT
