  • Your ePub Is Fine. Kobo Disagrees. Blame Adobe
    Interesting news! Though I'm on https://koreader.rocks/ like most people here, I suppose. - Source: Hacker News / about 1 month ago
  • Your ePub Is Fine. Kobo Disagrees. Blame Adobe
    Every Kobo reader is capable of running KoReader ( http://koreader.rocks/ ). That's the first, and probably last, step I'd take to render a book that the default reader takes issue with. - Source: Hacker News / about 1 month ago
  • Project Gutenberg โ€“ keeps getting better
    On any device you can install KOReader, PG is one of the default options in the builtin OPDS browser. https://koreader.rocks/. - Source: Hacker News / 2 months ago
  • Americans still opt for print books over digital or audio versions
    "Reading on a E-device is a bother, I have to sift through all the "sponsored" books and whatever other crap the ebook reader company decides to add, and be at the whims of whatever they decide they want to do with "your" device that day." My fellow, you are on Hacker News. Think like a hacker, not a consumer. Plenty of savvy e-book customers here don't have the experience you just described. Look up how to put... - Source: Hacker News / 3 months ago
  • Kids Rarely Read Whole Books Anymore. Even in English Class
    > Paper books are too hard to sell after you have read it. Still accomplishes the goal of allowing kids to read a book. > Ereaders can not render PDF/DJVU with formulas. My reading list has nothing able to be read from that kind of devices. Kids don't usually have these sort of requirements with their reading lists. Also have you looked into KOReader[1], which has support for djvu it looks like? > Installing some... - Source: Hacker News / 7 months ago
  • I Bypassed Amazon's Kindle Web DRM Because Their App Sucked
    Jailbreak it and install KOReader[0], which supports PDFs. You can also install something like Project Title[1] for a fancier UI https://koreader.rocks/ https://github.com/joshuacant/ProjectTitle. - Source: Hacker News / 9 months ago
  • Mozilla shutdown Pocket on July 8, 2025
    I use KOReader [1] on my Kobo. It supports Wallabag [2]. Wallabag offers both hosted [3] and self-hosted options. There's also a standalone kobo client for Wallabag [4]. In addition, Wallabag also supports direct import from Pocket.

  • All Kindles can now be jailbroken
    Highlighting the very popular app enabled by this, KOReader: https://koreader.rocks/. - Source: Hacker News / over 1 year ago
  • ElevenReader by ElevenLabs
    You can jailbreak you kindle [1] and install KOReader[2] and this will allow you to do this science fiction. [1] https://kindlemodding.org/jailbreaking/WinterBreak/ [2] https://koreader.rocks/. - Source: Hacker News / over 1 year ago
  • Pagination widows, or, Why I'm embarrassed about my eBook
    Have you tired KOreader[0]? It supports multiple ebook formats, including epub and cbz. You'll need to jailbreak[1] your Kindle though. [0] http://koreader.rocks/. - Source: Hacker News / over 1 year ago
  • PineNote Community Edition
    I love my old Kindle Touch. The #1 thing that keeps me using it is a community-maintained e-reader software you can run on it that makes it much more usable without Amazon's support: http://koreader.rocks/ My #1 priority for new hardware nowadays is making sure it's not dependent on OEM software. Nothing sucks more than buying a device for a selected purpose, and then not being able to use it fully because some... - Source: Hacker News / over 1 year ago
  • Ask HN: Best offline-only eBook reader?
    Get any Kobo and immediately install koreader: http://koreader.rocks/. - Source: Hacker News / almost 2 years ago
  • Foliate: Read e-books in style, navigate with ease
    Have you tried KOreader? https://koreader.rocks. - Source: Hacker News / about 2 years ago
  • Combine multiple RSS feeds into a single feed, as a service
    I think koreader[0] has an RSS feature where you can fill in some RSS feeds and it converts feed items to epubs. Instead of following a bunch of them and having to sync them I guess you could just follow the combined one and be done with it. If you have multiple feed readers, each with their own way to input feeds, I think this might be an easy solution. [0] https://koreader.rocks/. - Source: Hacker News / about 2 years ago
  • Ask HN: ePub reader with sync for iOS/Android and Linux
    KOReader - https://koreader.rocks It can also be installed on Kindle, Kobo, Pocketbook. - Source: Hacker News / about 2 years ago
  • Conversion from epub to kepub, and related Calibre use
    I only read kepub files on my Kobo Clara 2E (kobo stock). I use KOReader to read PDF, CBZ (comic files) and epub. Source: over 2 years ago
  • First E-reader. I am thinking of buying Kobo Libra 2?
    You can easily modify it (like adding KOReader). Source: over 2 years ago
  • Calibre โ€“ New in Calibre 7.0
    It doesn't try to solve the same use cases that Calibre does, but I built an open source (EPUB only) manager / reader / statistics tracker called AnthoLume [0]. It mostly stemmed from me reading in KOReader [1] on my Kindle, and not having the ability to sync the progress to my iPhone / iPad. It's got metadata matching, support for multiple users, and statistics tracking which allows me to have a "Leaderboard"... - Source: Hacker News / over 2 years ago
  • Show HN: News2reader โ€“ Readable articles from HN and Pocket on your e-reader
    Hi! I recently became the owner of an e-reader, and wanted an easy way to get web articles from Hacker News and my bookmarks onto the device, on-demand, for easy reading. I'm using KOReader (https://koreader.rocks/) on my device, and like lots of e-book readers it allows browsing online catalogs of books (e.g. From sources like Project Gutenberg) using the OPDS protocol. News2reader is a self-hosted Node... - Source: Hacker News / almost 3 years ago
  • Is the pocketboom era the right choice for me ?
    No I don't have any special lag. But I also don't use the default reading app, I use Koreader. I think the normal reading app also doesn't have much lag. Most modern eReaders have much less than 5s lag. Source: about 3 years ago
  • InkBox OS โ€“ open-source, fully-functional standalone OS for Kobo's eReaders
    For any Kobo (as well as Kindle & PocketBook) owners considering stock firmware alternatives, there's also [KOReader](http://koreader.rocks/)l. - Source: Hacker News / about 3 years ago
