This is what we've built RemNote for! You can add your sources (PDFs, websites, YouTube, etc.) and create cards directly from them. Either with AI (click on a sentence => get an AI card), or by highlighting a sentence and writing your own card.

It's not at the OS level, but I think a focused standalone all-in-one experience is actually better. We've explored a chrome extension here that does something similar to what you suggest, but it somehow hasn't proven useful in practice. I always keep coming back to just doing everything directly in the tool (upload PDF, take notes, make cards), as it helps me focus deeply on what I'm learning.

I tried Remnote yesterday for the first time, after another user in this same thread recommended it.

I put a paper in, and clicked a sentence and ... it is somewhat magical. This is exactly what I meant, somewhere to have PDFs etc. and an easy way to make cards immediately.

I bought pro with AI, and then I put a full paper in. I asked the AI to make flashcards of the whole paper; it worked so well, it's basically SuperMemo's original idea of incremental reading.

Looking forward to using it more, thanks for your hard work.

Love RemNote -- ability to take notes and create SRS cards within the notes is so sick

Does RemNote use the algorithm described in the link or something else?

[mfranzs]

Yep, you can either use FSRS (the one described in the link), or Anki-SM2.
