General Discussion / Feedback Calibre users: I built a Quest e-reader that reads whatever you export (EPUB/MOBI/PDF/CBZ). Curious how you'd want it to talk to Calibre.

2 Upvotes

Solo dev and a Calibre user. HoverTome is an e-reader for the Quest — your own files, no account, offline. EPUB is first-class; MOBI and CBR auto-convert on import; PDF and CBZ too. 11 typefaces, margins/spacing, dark page, offline dictionary, chapters, bookmarks.

Right now the workflow is: export from Calibre, copy to the headset over USB (or download in the headset browser), tap Scan. It works, but I know this community would want better. Options I'm weighing:

  • Calibre device plugin so the Quest shows up as a device and "Send to device" just works
  • OPDS catalog support so you point HoverTome at calibre-server on your LAN
  • Wireless device connection

Which would you actually use? Store page if you want to see it: https://www.meta.com/experiences/hovertome/1056683397316514/ ($9.99 once) — site with a browser demo: https://www.hovertome.com

Support / How-To Adding Page Menu to Epub

3 Upvotes

Hello! Hopefully, my title is fairly clear. I'm hoping someone can help me out. I recently obtained a manga from a friend entirely in JPEG. I combined the jpegs into a single PDF then created an epub from that file! Great!

While the file works pretty well, there is no way to go through the pages unless it is individually page for page (there is no menu to jump to pages) is there a way to set it up so I can jump to different pages? I am fairly new to the program and am just learning. I don't have too much experience in coding, but I am willing to try!

General Discussion / Feedback Looking for a plug in

6 Upvotes

So i'm working on cleaning up my library and was wondering if there were plug ins that yall recommend for auto genre tagging and then being able to filter them by genre to and marking them so that they can be easily found to create the genre tag under a custom column and a way to run a check to filter out books that won't load or are 'broken' for whatever reason and then mark those so I can put them into a custom column that I already have set up?

Support / How-To Alternative to Calibre Companion?

6 Upvotes

I have used Calibre Companion with no issues for many years to transfer books from PC where they are stored to my phone and tablet. But I just got the Galaxy S26U and it no longer works. It opens and closes immediately. According to Google Play, it has not been updated in 3 years.

Any safe alternatives?

Support / How-To Question about setting reading position

2 Upvotes

Hey all,

I've been really getting into the weeds with Calibre, as I'm sideloading my books now. I have installed, and now using KoboUtilities. There is a book which I knew I was 45% of the way through.

I sideloaded the book to my Kobo, set the reading position in Calibre, and then used KoboUtilities to 'store/restore' the reading position of that book.

When the Kobo had refreshed, it showed me that the book was now at 45%. Success! However, when I opened the book, it opened at page 1 and reset the reading position. My expectation was that, since Calibre had successfully set the reading position of the book, when I opened it, I would open at 45% of the way through, but this did not happen.

Can anyone show me what I'm doing wrong?

Support / How-To DRM Removal (Not Kindle)

2 Upvotes

Hi everyone,

I bought an ebook from a Danish ebook library for people with dyslexia. When we purchase/download these books, we receive them in EPUB format, but they can apparently only be opened using Thorium Reader with a code to unlock the DRM.

I'd really like to remove the DRM so that I can use the book as a PDF instead. Does anyone know how I could do this?

Most of the guides I've found seem to focus on something called "Kindle" or other DRM systems that I don't think are the same as the one I'm dealing with. I've tried following some of those guides anyway, but unfortunately without any luck.

Any advice on what type of DRM this might be or where I should look for a solution would be greatly appreciated. Thanks!
