Plato

Plato is a Kobo-only e-book reading application, with similar features to KOReader while maintaining a much cleaner and easy-to-use UI. Plus, the fact that it is only available on Kobo means that it has been developed specifically with Kobo users in mind and with less of the weird bugs that might occur when other applications might target several devices.

Plato cites its main features as:

  • PDF reflowing and cropping, similar to KOReader
  • Support for popular formats, including PDF, CBZ, EPUB, and DJVU
  • Contrast adjustment
  • Screen rotation
  • Custom dictionaries
  • Annotation, highlight, and bookmar ksupport
  • Customizable online source retrieval for books

Prerequisites

What you need

  • The latest release of Plato

Installation

  1. Ensure your Kobo is powered on, then connect it to your computer
  2. You should be prompted to accept the connection on your Kobo. If so, click "Connect"
    • If your connection is cutting in/out, STOP! Get a better USB cable
  3. Create a folder named plato in .adds on your Kobo
  4. Copy the contents of the Plato .zip to the .adds -> plato directory on your Kobo
  5. If you don't already have plato.png on the root of your Kobo, you can get it from the KFMon ZIP
  6. Safely eject your Kobo, then unplug it
  7. Allow your Kobo to reboot

Installation complete!

Plato will be accessible by clicking the book labelled "KOReader".

Method 3: NickelMenu users
