Kiwix
Offline Wikipedia reader
Kiwix is an offline reader - meaning that it allows you to check text or video that is normally only available onthe internet.
We turn various online educational contents (such as Wikipedia, for example) into ZIM files, and these can be openedby Kiwix even if you have no connectivity whatsoever.
Kiwix is an offline reader and manager for online content like Wikipedia, Project Gutenberg, or TED Talks. Kiwix allows you to read and search through offline content as they were online. Similar to a browser, Kiwix works with the highly compressed ZIM file format.
