Everything here is a Cut — one idea in ~180 words, dated, and free to reuse. Read them like short posts. Or use the trick this site is built for: every page carries recipes. Click one and it copies the note plus an instruction to your clipboard; paste it into ChatGPT, Claude, or Gemini, and the idea gets re-cooked into whatever shape you want.
Try it now — a recipe, live
One click copies the recipe plus the full note — paste it into any AI, nothing else needed. Or read the note itself →

on their own. Running an agent instead? Point it at
/llms.txt and skip the reading layer.
