I tried to put together something similar… I guess it is reassuring that others are struggling to find a nice e2e setup as well.

I was intending to vibe code the whole pipeline then stumbled onto Readwise, $10/mo is currently cheap enough to prevent me from building my own.

(I splurged on the Boox so I could easily use/build Android apps on the reader/collection side.)

It does feel like there is a big OSS gap here, and I wish Readwise luck on commercializing too.

From my side the remaining piece is building my own recommendation / crawling pipeline to expand my set of RSS feeds, feels like a good project to add on and Readwise seems quite extensible so it’s a good base to build on.
