This looks like it could be a sensible way to use LLMs in programming, although I'm not convinced AI-generated documentation can give meaningful explanations rather than paraphrase. However, since the generated wiki is editable, it seems it can be used to give a kick start to internal documentation and let the actual devs step in when it's required. I'm skittish about genAI in the workplace (or anywhere really) but this could be valuable.

However, and this might have been naïve of me, but I expected some sort of local model. And I see that you have to bring in your own vendor API keys, which implies that you let AI companies mine your codebase. Isn't that a no-go for most companies? So far I've only worked in places that banned ChatGPT over IP concerns like these. Is it already common for businesses to feed their codebases to third party LLMs?
