What Jamie wrote
Willison put his LLM pricing calculator tool on a standalone website and added some new features. I debated linking right to the tool but this short writeup highlights how is using LLMs to actually make the tool as well. This highlight "using a vibe-coded bash script that I forgot to save anywhere" feels about right. He's adding features using LLM as well, and using AI for design elements.
