Digital Learning That Works Without the Internet
An offline-first learning solution for system integrators delivering NGO, government and rural school projects. Teach anywhere — no internet, no problem. We design the solution and supply the hardware; you deliver it on the ground.
Built for Places the Internet Hasn't Reached
This solution sells one thing above all — deliverability. Real learning, in real conditions, with or without a network.
Works Fully Offline
A local content server delivers lessons over a local network — no internet connection required to teach.
Low Infrastructure
Low-power devices and battery backup. Designed to run where power and connectivity are limited.
You Control the Content
Built on Kolibri. Load your own curriculum and local-language materials. We give the platform; you keep the content.
Ready to Deploy
Built from proven hardware — tablets, charging carts, access points — so projects ship and scale fast.
Three Deployment Levels — From a Mobile Lab to a Whole School
Pick the level that fits your project's scale and budget. Every level runs fully offline and comes with a complete BOM.

How an Offline Classroom Actually Works
No internet reaches the devices. A local content server hosts everything, and tablets connect to it over a local network — fully self-contained.
(Kolibri host)
(no internet)
(class set)
(store & charge)
The content server hosts all lessons locally — no internet is needed for students to learn, stream video, or take quizzes.
When a connection is available, the server syncs new content and student progress — then works offline again.
The access point needs a PoE switch (802.3af/at), supplied by the system integrator — not in the Tralltech BOM.
Designed for low-power, limited-grid sites. Power — mains, solar or generator — is arranged on site by the integrator.

Frequently Asked Questions
Can students really learn without any internet connection?
Yes. A local content server hosts all lessons, videos and quizzes, and tablets connect to it over a local Wi-Fi network. No internet is required for daily teaching. When a connection is occasionally available, the server syncs new content and student progress, then continues working offline.
What software runs the offline learning platform?
The solution is built on Kolibri, an open-source offline learning platform. You load your own curriculum and local-language materials onto the content server. We provide the platform and setup guidance; you keep full control of the educational content.
Do you sell directly to NGOs and governments, or through system integrators?
We work exclusively through system integrators delivering NGO, government and education projects. We never contact your end clients directly, and an NDA is available on request. The project, the relationship, and the margin all stay with you.
How does this solution handle sites with unreliable power?
The devices are low-power and support battery backup, so they are designed for limited-grid environments. The power source itself — mains, solar or generator — is arranged on site by the system integrator according to local conditions.
Can I start with one mobile classroom and scale up later?
Yes. The Level 1 Mobile Lab equips a single class set with a content server, tablets, charging cart and access point. You can add more access points, tablets and a higher-capacity server to grow toward a whole-school deployment.
Do you provide documentation we can submit in a tender?
Yes. We provide offline architecture diagrams, complete BOMs, and technical documentation ready for you to put your name on and submit to an NGO, ministry or tender.
