Ask HN: Software to annotate web pages with stylus?

Maybe it's just me, but when I read things like [1]. And then read the HN discussion about it [2] and see more notes about it [3]. I just want to save all the three tabs (+ more I found via searching on DuckDuckGo), get the materials locally and potentially edit the text by typing, be able to highlight it and to be able to use my stylus for writing and doodling in the margins. Does anyone know of such a project? If not, then hereby I offer it as a side project idea to anyone who's willing to do it. That person may very well be me.
