    The GitHub readme may have been a better link to use, it contains some more information: https://github.com/koreader/koreader

    - portable: runs on embedded devices (Cervantes, Kindle, Kobo, PocketBook, reMarkable), Android and Linux computers. Developers can run a KOReader emulator in Linux and MacOS.

    - multi-format documents: supports fixed page formats (PDF, DjVu, CBT, CBZ) and reflowable e-book formats (EPUB, FB2, Mobi, DOC, RTF, HTML, CHM, TXT). Scanned PDF/DjVu documents can also be reflowed with the built-in K2pdfopt library. ZIP files are also supported for some formats.

    - full-featured reading: multi-lingual user interface with a highly customizable reader view and many typesetting options. You can set arbitrary page margins, override line spacing and choose external fonts and styles. It has multi-lingual hyphenation dictionaries bundled into the application.

    - integrated with calibre (search metadata, receive ebooks wirelessly, browse library via OPDS), Wallabag, Wikipedia, Google Translate and other content providers.

    - optimized for e-ink devices: custom UI without animation, with paginated menus, adjustable text contrast, and easy zoom to fit content or page in paged media.

    - extensible: via plugins

    - fast: on some older devices, it has been measured to have less than half the page-turn delay as the built in reading software.

    - and much more: look up words with StarDict dictionaries / Wikipedia, add your own online OPDS catalogs and RSS feeds, over-the-air software updates, an FTP client, an SSH server, …

    Oh man I absolutely love the work that you guys do. I'm actually in the process of learning Ebook production using the 'Step by Step' guide on your website. I'm essentially learning it all from scratch as I have little to no programming/SWE experience (I learned a bit of Lua because of KOReader[1]) but the technical side of ebook production has always fascinated me enough to keep learning.

    I read that KOreader is unstable on the Libra 2[0], so I haven’t installed it yet even though I would like to. What has been your experience running it?

  • Conversion from epub to kepub, and related Calibre use

    I'm using Kobo Clara 2E (6" screen size), and it is unpleasant to read PDF and CBZ files (comic/manga) since Kobo only provides zoom and orientation mode. I installed KOReader on my Kobo. It has more setup to display those files way better. The views of PDF in KOReader and Comic in Koreader. I read Epub files in Koreader to maintain its original format.

    I only read kepub files on my Kobo Clara 2E (kobo stock). I use KOReader to read PDF, CBZ (comic files) and epub.
  • Calibre – 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" that shows how fast you read (words per minute). Fun competition between my wife and I (that I'm 100% losing). It's a Progressive Web App and utilizes a Service Worker to support 100% offline reading as well.

    There's a demo server [2] (creds are "demo" for both user & pass).

    You can still choose automation. The easier route for me is to use wallabag to save the article. Then on my remarkable tablet I can grab a very readable document with https://github.com/koreader/koreader.

    The other option is to use https://github.com/danburzo/percollate to convert a webpage to a nice document directly. I use both tools depending on my needs.
