reMarkable Paper Pro
KOReader
Installing and living with the KOReader reading app.
The Paper Pro’s stock EPUB reading is weak, and KOReader fixes that. Unlike a Kindle, no jailbreak exploit is needed — reMarkable includes a developer mode that gives you SSH access to the device, and the community package manager Toltec installs KOReader over that connection.
Why do it
- A real ebook reader. Proper font, margin and layout control, library management, and formats beyond PDF and EPUB — CBZ, FB2, DjVu and more.
- Better PDF reflow than the stock reader for small-text documents.
- It runs alongside the stock software. You launch KOReader from a menu; the reMarkable writing side is untouched.
Why you might not
- It is advanced. You enable developer mode, connect over SSH or USB networking, and run command-line steps. A wrong move can require a reset.
- Firmware updates can break it. A reMarkable update may disable developer mode or remove Toltec’s changes; you re-run the install afterwards. Some people hold back updates while running it.
- No pen support. KOReader is a reading app — no handwriting, no notebooks. You use it for reading and switch back to the reMarkable software to write.
- Warranty and support. reMarkable will not support a device with community software on it.
