eBook Creator gives you custom controls to automatically or manually create Mobipocket .mobi files. Mobipocket files work natively on the Kindle family of eReaders and on iPhone, Android, Windows, OSX , and other platforms through free software.
eBook Creator can create eReader files from any RSS or Atom feed, supported by all WordPress installs, or create your entire blog as an eReader file. It can be setup to generate new Mobipocket files every day, every week, every month, or every time your blog is updated. It can generate custom books from individual blog posts or from any post category in your blog.
All of these files can be seen, managed, and downloaded through WordPress’s built in Media Library.
A handy widget has been provided for announcing your eBook capabilities to your readers.
