It looks hybrid human/LLM at best, but definitely possible that it's mostly human, from someone who is earnestly learning how to use "pitch" language. I got the feeling that some parts, like the bullet points, maybe originated from AI-generated documentation/readme's.

My intuition tells me that it could have been AI-generated, but if that's the case then it was heavily edited by a human. I think anyone who went through it for that would have changed other things as well. That's why I suspect it's pseudo-artificial pitch "coded" human writing with some (mostly, lightly edited) copy/paste of AI bullet points.

Then again, I can't find snippets of this language in the repo, so maybe I'm losing my discernment as LLMs advance (as well as the humans who are learning how to use them).
