WordDumb VS calibre

Manual here: https://xxyzz.github.io/WordDumb/

X-ray. You want X-ray. For sideloaded books you can try https://github.com/xxyzz/WordDumb

What part are you failing on? The earliest one, assuming you have Calibre installed already, is that you should be downloading from the releases page and not trying to download the entire code repository.

First option is to use Count pages plugin, and second option is to use kfx output, which you can enable option to create approximate page numbers. Also worth mentioning that the kfx outputs also supports x-ray and word wise, if you use WordDumb plugin.

github page here, mobileread page here

Since that itself is pretty opaque to non-techies, the Wordumb home forum is here, and it looks like the github page you need page is here.

WordDumb You can use this to generate Word Wise and X-ray for your ebooks.

go to calibre prefrences, click on plugin, click on install new plugin search for kfx output, kfx input and worddumb (documentation for these plugin is availabe here kfx output , kfx input and worddumb ) (note: for worddumb you also need to install python)

Not to be confused with Calibre, the excellent ebook software by Kovid Goyal:

Glad you were able to fix it, but what about trying Calibre? It is free and makes it easy to adjust things, add info, and change front covers.

Or using Calibre (pdf or azw3) https://calibre-ebook.com

There are already some very good ebooks solutions out there so there's really no need. Calibre for the backend and database management, Calibre-Web for the front end, and Openbooks for content.
