Claude Code built the features I've been asking for in my favorite app, and it took 30 minutes

Karakeep is one of the apps I use every day, and I’ve wanted to add a few things to it for years. I wanted to keep sources, notes, and highlights together around a story, ask questions about what I’ve saved, and compare articles that answer the same question differently. Having all that inside the app where I already save everything makes so much sense.
