Good overallby Abraxas Mar 06, 2026 (Read all my 5 reviews)

It does the job. The interface is clean and the settings as easy to find as in any similar program. I don't like the way it truncates book names and adds numbers to the titles. With multivolume sets this makes the titles indecipherable. Review details

The best software evah!by objective May 02, 2020 (Read all my 14 reviews)

Calibre is by far the best software in the world. Not just e-book manager, but software--the best ever. I nearly broke my forefinger clicking the "YES!" radio button for "Would you recommend Calibre to others?" The interface is perfect, it is 100 bug-free, and it cures cancer. I mean none of this, but my honest review was censored, so I'm lying to be censored again, because this site is so righteous. Best. Evah! Review details

Clunky interface, bad setting controlby JohnCorliss Apr 25, 2020 (Read all my 26 reviews)

I've been using this program because there's almost literally nothing else out there for what it does. I don't like the way that the program makes a copy of a file you only want to briefly look at, then stores it in its "library". I've been unable to find a way to turn this "feature" off. The interface is poorly designed and difficult to understand, the program itself is unnecessarily huge (165mb currently for an e-book reader? Really?) and is updated far too often. The updates are a pain to continuously implement. I've moved on to other programs. Review details
