Internet-in-a-Box delivers the world’s best free knowledge to anyone, anywhere. Knowledge to Go extends the reach of those resources to billions more devices that are already in the field: Android phones.
No mobile data, no internet connection, no additional hardware. Just a direct link to the world’s greatest resources.
Built on the foundation of Internet-in-a-Box, Knowledge to Go (K2Go™) transforms the most common computing devices in the world—Android phones—into standalone, offline digital learning hubs that deliver a world of information without needing internet access.
The K2Go app turns almost any Android phone in to a local server. Anyone in range can connect via local Wi-Fi (no internet needed) without installing additional software.
With just a few taps, anyone nearby can access more than 4000 offline educational resources in different languages, including Code on the Go, developer documentation, Khan Academy, Free Code Camp, MIT BLOSSOMS, Wikipedia, world maps, Project Gutenberg, textbooks, reference materials, complete Kolibri courses, and more.
Built on Internet-in-a-Box (IIAB): K2Go leverages the proven, open-source IIAB architecture, which trusted by schools, clinics, and communities in over 100 countries.
No specialized hardware: Instead of requiring additional hardware like a Raspberry Pi or another dedicated server, K2Go can use Android’s native Wi-Fi to host and serve content locally. No new equipment needs to be purchased.
Simple setup: Setting up K2Go is easy, with no commands to type. Just install the app, decide what kinds of materials you want to share, and download the content. To share, tap a button to display a barcode. To connect, scan the barcode. Read the documentation.
Create new servers without new hardware. The K2Go app can turn any other Android phone into a K2Go server without ever needing to go online, so people can bring K2Go resources back to their homes and communities using only their phone.
On September 15, 2026, the Offline Internet Consortium sponsored a webinar where the App Dev for All team introduced Knowledge to Go.
K2Go comes in three versions, so pick the one that fits your needs.
If you plan to distribute K2Go to other phones, get the universal app so you can set up K2Go on any kind of phone.
If you’re installing on your own phone and don’t plan to share it, or if you have very limited free space, get the version designed for your phone:
Download Knowledge to Go (approximately 38 MB)
Download Knowledge to Go (approximately 30 MB)
Download Knowledge to Go (approximately 28 MB)
In the Downloads folder, tap the file you downloaded. (It will begin with K2Go.)
