This is probably more feature creep than you can or want to sign up for at the moment, but I also don't really want to deal with manually transforming my Markdown or HTML into the sections of text that you use as input for embeddings. It would be nice if I could just provide URLs to my live documentation or Markdown source code, and your service takes a best guess at how to split it up into sections and then generate embeddings for each of those sections.
Last, I would be happy to talk to you all about docs strategy for your own docs sometime (I'm not looking for work at the moment; I just enjoy helping people with this stuff). You can contact me and learn more about my background via the social links on https://technicalwriting.tools (a blog about technical writing tooling topics that I just spun up).
Good luck!
