I'm the founder. Digiplot extracts the underlying data from images of charts and plots — you upload a figure, it returns the data as a table/CSV. Unlike WebPlotDigitizer and similar tools, it's fully automatic: no manual clicking on axes or data points.

I built it because I needed this tool for my thesis to digitize thousands of plots and there were limited options with varying degrees of success.

It's free to try on the link above with no signup — easiest test is to paste a chart whose real values you already know and check the output. I know the obvious question is accuracy and whether it hallucinates points. On an internal test dataset it performs extremely well on plots with a sensible amount of curves. Still performs well with 8+ curves in a single plot but depends on complexity.
