Many cannot easily access the internet, perhaps because of geography, economics or political problems. People without a reliable connection may be denied important resources which are only available online.
While nothing can replace the internet completely, there are ways to make offline life easier.
Kiwix is an app that lets you browse educational resources (such as Wikipedia, Stack Exchange, Wiktionary etc.) without an internet connection.
You install the app and download the content you want from the Kiwix website. You can then browse the content without an internet connection, because Kiwix content files are huge and include entire websites instead of just pages. For example, some sailors download the whole of Wikipedia for Kiwix while at port so they can browse it while at sea.
Kiwix content can also be sent through the post on a memory stick, or physically carried to remote regions. In short, it makes the internet more like a set of books that can be taken to places without the internet.
Briar is an encrypted instant messenger that connects to contacts via the Tor network. If internet isn’t available, you can also connect directly via Wi-Fi and Bluetooth.
Briar works without any central servers. It is especially suitable for journalists and activists who are operating in environments where communications are difficult.
Scuttlebutt is a social network with no servers. All your data is stored on your own computer or phone, and you can use it offline.
There’s a mobile app for ScuttleButt called Manyverse and a desktop app called Patchwork. Some parts of it are still in development, so it can be tricky to use.
