WorldBrains Memex VS Hypothes.is

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.

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

I honestly can't imagine not using extensions. I'm 39 and have been on the web since Netscape etc in the early 90s and I honestly care more about the extensions than I do anything the browser actually does. Like, if there were no extensions I don't think I'd care at all if I used Firefox, Chrome, Opera, etc. But Chrome and Firefox have this massive, massive ecosystem of productitivy improving extensions.

Not native to Gmail, but there are some tools that allow notes and comments on web pages as an extension. https://web.hypothes.is/ does this and is open source (if that matters to you). Source: 10 months ago
