Today, I wrote a small web-utility to digitize old plots. You upload an image or pdf of a plot, and extract data by clicking points on the curve. It is available at https://tools.dilawars.me/tool/plot-extractor. Why do this manually when AI can do it for you? First, because I wanted to write an utility and AI doesn’t always do a better job than a person!

This utility is a web-companion to to a somewhat popular Python utility I wrote a few back to digitize plots in batch mode.
