The development of BookONO is paused until we can find some time and/or money to work on it. You can help make BookONO happen by donating $50, a hundred donations buys you 30 days of development. We will also make it open source if $50,000 is donated and drop everything and bring to version 1.0 ASAP. So far $0 has been donated (this number is updated daily).



BookONO, formerly Gnosis, is a free e-book manager and convertor designed as a compliment to Calibre. It is written in C++ using the Qt4 (soon to be QT5) Toolkit. It isdifferent from Calibre in that it makes a few different design decisions than Calibre, for instance it does not attempt to put all your books in its own library or change their names. Where Calibre attempts to take complete control over your books, BookONO gives you control over your books. BookONO further attempts to take a different direction in terms of its UI, providing a more user-friendly, aesthetically-pleasing experience than Calibre.

BookONO does not attempt to reinvent or rewrite Calibre’s programming, instead calling Calibre to do many of the tasks that Calibre already does… We hope in the future to rewrite slow aspects of Calibre, naively in C++; but leave the rest of the job to Calibre which Kovind Goyal has obviously put a lot of thought into and we’re grateful for that.

In addition to the standard features of managing books, BookONO also includes an internal browser. The browser allows you to convert any web page to PDF and store in BookONO.

BookONO allows provides multi-client syncing and cloud services which allow you access your books anywhere.
