i'm assuming this is written with LLMs given the writing on that page and the nature of the other "products" on that website. i would not call that hand-written, as the page does in the second paragraph

I did use LLM for the landing page since I don't have much time on it. The browser however not that much. I did use claude and my own cwcode to help developing this, but a lot of times the zig code had to be written by hand. Hope this answered your question.
