Meet the little device that is changing the world, one school at a time.

RACHEL is a portable plug-and-play server which stores educational websites and makes that content available over any local (offline) wireless connection. RACHEL makes deploying a library of digital content as easy as pushing a button.

How it works

Anyone can purchase RACHEL from our online store, and we also have instructions for building your own RACHEL.

Then simply turn it on. While RACHEL is on, take your device and connect to "RACHEL" as you would any wifi network. Then open a web browser and type the web address (a number listed on the front sticker of your RACHEL).

Once you're connected to RACHEL, you can instantly access offline versions of the world's best free educational websites including Wikipedia, Khan Academy, and over 100 more. Learn more about the content stored on RACHEL, OER2Go.

what makes rachel revolutionary

RACHEL can instantly turn a graveyard of unused computers into a learning center. For the 53% of people around the world without an internet connection, RACHEL is a valuable tool that connects offline learners to the best free educational resources. RACHEL is rugged, lightweight, and designed to travel anywhere.

RACHEL is used by schools, libraries, community centers, orphanages, and the NGOs supporting them all over the world.

RACHEL is an amazing tool especially for kids in rural isolated areas. Our preliminary trials are showing huge leaps in understanding in the kids and continued enthusiasm for attending - even at the 10th week.

Probably my all-time favorite is the RACHEL project, which bundles free educational and utility content (Wikipedia, Project Gutenberg, etc.) onto an SD card and serves it via Wifi to people who are beyond the current reach of the internet.
