This site is the Notion branch of Kai Course Notes — it hosts the web-native notes I write while studying, mostly co-drafted with Claude during study discussions. All course files (handwritten notes, LaTeX sources, homework, materials) live on GitHub; this site is for notes best read in the browser.
