Great to see new tools in this space. So far we have been using WebPlotDigitizer, it has recently released new versions that stopped being open source but moved to be a paid software, requiring login, plastered with AI advertising terms.
Most of the time, I just use it to scrape original data from screenshots taken from research papers where the data is not provided as a table. I would say 7/8 of these figures are scatter plots from experimental measurements.
