My girlfriend recently got into making sourdough and wanted to keep a log of all her recipes. She really wanted to explore the relationships between recipe water percentage and crumb density, or proof time and oven spring, for example. I built her https://sourdoughchronicle.com - a local first bread journal that allows peer to peer recipe and results sharing. Claude + aider had a MVP built in an hour and she's loving it! Oddly enough the comparison charts haven't made it in yet, but that's the next feature on the the to-do list.
