Kiwix
Kiwix is a browser that allows users to access web content, such as Wikipedia, without an internet connection by downloading and locally storing highly compressed copies of websites onto phones or computers. Users can then search, read, and interact with this content.
Dedicating to providing offline access to educational content in areas with limited or no internet access, Kiwix has about 10 million users worldwide. A nonprofit organization and a free and open-source software project, Kiwix is commonly used in educational humanitarian and remote settings to ensure that knowledge remains available even when the internet is not.
