Yes. Only one solving the problem very very well right now. Memex - https://getmemex.com More generally the open annotations standard is meant to address this use case. Older, now obselete tools like hypothes.is, and peerlibrary* laid a lot of the groundwork. https://github.com/peerlibrary/peerlibrary. - Source: Hacker News / almost 2 years ago

Hmm.. Probably Wallabag, But I prefer MemeX because it has less trackers and works well for me. Source: over 2 years ago

Check out Memex (https://getmemex.com/) or wallbag (https://www.wallabag.org/en). They're both free and open-source. Source: over 2 years ago

If you're interested in saving bookmarks and such, I'd probably go off with something like Memex (https://getmemex.com/) or Floccus (https://floccus.org/). I haven't really used them but, I've looked a bit into them and they're free and open-source. Source: over 2 years ago

For pdf annotations on Windows I use Foxit reader, on Android acrobat reader. For highlighting web-content (pdfs, articles) I'm still looking for a good solution but will maybe stick to Memexor hypothesis. On iOS there's Command Browser (one time purchase) I already use and love for webcontent- and they have Android on their roadmap too.. If that's the case I know where I belong ;).

Hey, how it's going? I'm New-Needleworker-379. And today, I'm planning something to do in July 23: I'll add one page every day on Firefox on myfav.es! Source: almost 2 years ago

P.S. All these apps will be extracted from myfav.es's Site Catalog, sorted by popularity. Good luck starting on July 23! Source: almost 2 years ago
