One feature that would make it super useful is to have 30-60 seconds of audio (AI generated) that tells me enough high level info about the paper to know whether I want to go deeper (and 'save for later' button to go with). That way a user can use it while commuting or driving.

Again, really cool idea that helps people learn things instead of wasting time on same old tiktoks/reels. Nicely done, OP!
