Roast it. Taste it. Nail it.

A free roast log for home roasters: green coffee, roast batches, Kaffelogic .klog files and how every roast tasted, so you can see which recipe worked. With Pro, talk to it from your phone in the Claude app: it logs your cuppings and brews and tells you what to change next.

Works with Claude on your phone and desktop. Pro starts with a 14-day free trial, and the tracker stays free.
