Somewhat inspired by it, I&#8217;ve been working on a combined chart snipper and OCR text+table sampler. Desktop rather than web-based and built using Python, tesseract, and openCV. MIT licensed. Some instructions to get started in the readme.<\/p>\n<p>Chart snipping should be somewhat familiar to <a href=\"http:\/\/automeris.io\/\">automeris.io<\/a> users but it starts with a screengrab. The tool is currently interactive but I&#8217;m thinking about more automated workflows. IMO the line detection is a bit easier to manage than it is in automeris with just a sequence of clicks but you can also drag individual points around. Still adding features and support for more chart types, better x-axis date handling etc. The Tkinter GUI has some limitations (e.g., hi-res screen support is a bit flaky) but is cross-platform and a Python built-in.
