Are there any good open source documentation chatbots that you can integrate into the search function of docusaurus? If you see commercial offerings like mintlify, they all come with a Q and A chatbot built-in. It’s not very hard to build, you just need to generate the RAG chunks at build-time but this is best implemented as part of the documentation software, rather than as a third party plugin since it heavily ties into the search feature.
