Kiwix

[To use this app you will need to download, for free, an archive with your chosen content – see the About page for instructions.] Kiwix is an offline reader for content from Wikipedia, Project Gutenberg, TED Talks, Wikivoyage, Stackexchange, etc. It makes knowledge available to people with limited or no Internet access, or to anyone who wants to have easy offline access to a vast repository of information. The software as well as the content is free to use for anyone.

You can get the whole of Wikipedia, Wiktionary, Wikivoyage, Gutenberg books, etc., on your device completely offline in your own language. You can have amazing reference tools at your fingertips wherever you are. Just download your chosen archive and store it on your device (see instructions from About page of app). Great for travelling, or any place where access to the Internet is difficult or expensive! Often faster than Wikipedia for quick consultation.

This app reads a larger offline file that you can download to your device. You must download the archive separately (see About tab in the app for instructions). Offline files are available for Wikipedia, Wiktionary, Wikivoyage, Wikimedicine, Wikimaths, TED Talks, Project Gutenberg, etc., in all the available Wikipedia languages.

This extension is very handy, always a click away in your browser. However, if you are using Windows 10/11, you can also find a convenient, self-updating UWP version of this app in the Microsoft Store (also made by Kiwix). It runs independently of the browser (search for Kiwix JS in the Store). There are also packaged versions which include the latest WikiMed (Medical Wikipedia), and Wikivoyage (just search for them in the Microsoft Store).

Please note that with this browser extension, unlike with the app versions, you will need to pick your ZIM file each time you open the app (this is an API limitation).
