This page has been live long before AI appeared, I used Quartz [1] v3, now at v5. But added some features I like with AI, yes, but still keeping my beloved color theme and web style as I had it for a long, long time. The whole code for the second brain (ssp.sh/brain/*) is on GitHub, in case you want to check it [2], but you can also see the "Changelog" in the footer to see recent visual changes. But I'd be curious what makes you think it's AI-generated?
