I’ve been into anime for years, so I made a sites.google profile to keep track of everything I watch. I list each series with my notes on arcs and what studio animated it—mostly Bones and Madhouse stuff. sites.google profile It’s not fancy, but it helps me remember which OP I liked or why I dropped a certain isekai. The downside? I spend more time updating the site than actually watching new shows sometimes. Still, it beats relying on memory or scattered notes.
