Describe the bug and copy the error message

Sorry to bother, but from what I read, WordDumb supports epub, mobi, and other formats, but it only works when I add an epub book. Is that right, or is it just me?

calibre, version 7.12.0

Honestly, even when using a MOBI file, it doesn't work (WordWise is not applying). This is what worked for me:

1. Download an epub book
2. Convert to AZW3 manually through calibre
3. Click on the WordDumb icon

I think the error message is pretty clear? Please convert book to a Kindle compatible format first, then run the plugin.

If azw3 works for you, mobi should also works.
