KOReader
Reddit take
AI summary of the Reddit excerpts below — not a quote
KOReader is a highly customizable, open-source document viewer designed for e-ink devices, widely considered a superior alternative to native Kindle and Kobo firmware. It is praised for its robust PDF handling, native EPUB support, and deep typographic controls, though it is frequently criticized for having a utilitarian, file-directory-based user interface that can be difficult for new users to navigate.
Pros
- Superior PDF handling and reflow capabilities compared to most native e-reader software.
- Extensive customization options for typography, dictionaries, and user-made plugins.
- Native support for a wide range of formats, including EPUB on devices like Kindle.
- Often more responsive and faster than stock operating systems (e.g., Kobo's Nickel).
- Supports advanced features like Wi-Fi book transfers and Anki card integration via plugins.
Cons
- The user interface is often described as dated, unintuitive, or 'weird' by those accustomed to modern apps.
- Navigation is primarily based on a file-directory system rather than a visual library gallery.
- Installation can be complex, particularly on Kindles where jailbreaking is required.
Caveats
- Installing on Kindle devices typically requires voiding the warranty through jailbreaking.
- Some users report specific hardware bugs, such as internal clock freezing on certain devices.
- Color vibrancy on specialized e-ink screens may appear less 'vibrant' compared to native applications.
Best for
- Power users who want granular control over their reading experience.
- Readers who frequently work with large or complex PDF documents.
- Users looking to bypass the limitations of locked-down ecosystems like Kindle.
Avoid if
- You prefer a polished, modern, and 'pretty' user interface.
- You are uncomfortable with technical setup processes or jailbreaking hardware.
- You want a simple, automated library management system out of the box.

However you have the option to install a third party reader (koreader) which supports more colours to highlight
If you already have KOReader on there, I've seen people change the usuable screen size parameter to line up with the working part of the screen.
You may want to try out KOReader on your Pocketbook for a faster experience
I've had a lot of luck setting up the KoReader app so that PDFs are the least pain possible to read on it, almost pleasurable even. So whichever reader you end up going with, I'd recommend it be one that can support KoReader for the sheer customisability of it.
You can easily install KOReader on them, though, and I've heard it's better with PDFs.
It allows you to install KOReader which is a MUCH better ebook reader than the native kindle one and natively supports common ebook formats(like epub)
With KOReader you can install the dictionaries you want and create anki cards with some plugins, and as i understand is quite responsive on any e-reader, so i would start recommending any e-reader minus the kindle.
It's an alternative reading software that can be installed onto basically anything... It allows a crazy amount of control over typography, you can install any dictionaries you want, etc.
KoReader
followed by KOReader, with Nickel, Kobo's default software, being the least responsive.
