Sounds like http://Readwise.io

I won't be at a computer for a while to dig up all the links; but check out both my comment and post history on HN; the short version is that I ditched Readwise, Instapaper, Pinboard & co, and my entire histories there, and wrote something from scratch tailored to my own needs which is now also publicly available at https://notado.app

I generally encourage people to write software that is tailored to their own needs in this area rather than trying to contort themselves to fit into the bookmarking model, which I personally consider to be broken for highlights (I've shared a blog on this topic on HN too).

If anyone were to ask me for advice after describing the sort of fatigue that you have described with the popular systems and services in this product area, I'd encourage them to ditch the "read it later" mentality and try adopting a "read it now or read it never" (RINORIN) approach, and to stop annotating their highlights (because these fall out of sync with our thinking incredibly quickly).
