I was wondering the exact same thing a few days ago and spent some amount of time googling it.
There’s already such a project actually, called Swanye. There seems to be a single person working on it, so if anyone has time to help I’m sure it will be appreciated
No, you’re right! But it’s only possible for epub/mobi and txt files.
Pdfs can be zoomed into, but then you need to scroll around the page and it starts feeling rather like you’re looking at the paper through a keyhole. I tried converting pdf to epub, but the formatting/page layout of the original matters and it doesn’t translate well.
Student here, journal articles are a lot easier to read on paper than on screen. After the first hour or so of screen reading my eyes get drier than the Sahara and I feel dizzy. I tried reading on my e-reader, but journals like to cram as much text on a page as possible, which doesn’t work well on a 6" reader.
Tidal’s pretty good, they cost the same as spotify but all accounts have access to lossless. The playlists it makes for me are no worse than spotify’s and I can sleep happy knowing the artists I listen to get compensated better than on either Spotify or Apple Music.
I also feel the app’s design helps me see music in the context of the album it was released in instead of as random tracks, which has made me reconnect with some kinds of music I’d grown apart from after I got Spotify.
