Photo Scrubber: Face Blur Running Fully in the Browser, Built by an AI
Simon Willison had an AI model build an experimental tool that detects faces and blurs them locally, with no upload. The tool is small, but the way it was built and the way it runs both matter to anyone shipping AI features.

Puter Compiled Firefox to WebAssembly — Built on a $25K Claude Tab, Paid Flat
Puter ported Gecko itself to WebAssembly so a full Firefox runs inside a browser tab — and the build is a real-world data point on what heavy agentic coding costs when it's metered versus flat-rate.
