I'm looking for an online research tool that will allow me to annotate & tag material I read online, and connect it to other material. The situation I'm imagining is something like this:
Read online article; find interesting/important information.
Remember important connection to an article I read six months ago, potentially useful in current or future project.
Find article from six months ago by searching tags.
Apply same tag to new article, plus a specific reference to the older article.
Annotate new article with relevant thought/observation/question/comment.
I originally imagined this as some sort of web-based overlay (e.g., a browser plugin), but I'd be open to downloaded software as well. Gratis is nice, but I'm willing to pay for the right tool. Cross-platform is important.
As for what's already out there: Pocket has tags, but not annotation; ditto Google Keep; DevonThink, which apparently still exists, feels like overkill; I did use Evernote a long time ago, but found it clunky and not really helpful. (If it's improved enough that I should try going back, I'm open to that.)
