Seen any developer docs with a RAG chatbot?

Creating a chatbot with access to a company's documentation, guides, and API reference material seems like an excellent use case for RAG. Developers could ask the chatbot how to build specific solutions with the company's platform and receive a response in the form of a tutorial.

Taking this further: if the developer verifies that the tutorial works, it could be submitted to the company for review. Chatbot-generated tutorials that are verified and reviewed could then be published as guides on the company's documentation site for other developers to find via Google.

I haven't seen any companies that provide such a chatbot. Have you?
