Education Should Be Accessible to Everyone

OneByZero is the student-powered marketplace where knowledge is shared, study materials find new homes, and every learner gets the resources they need, regardless of where they are.

Our Mission

We believe that the best study resources often come from fellow students. The notes that helped someone ace their exam, the textbook that's still in great condition, the tutor who explains concepts in a way that clicks.

OneByZero connects these students with each other. Sellers earn GyanisCoins for their materials, and buyers get quality-verified resources at student-friendly prices. It's a circular economy built for education.

As part of the Gyanis ecosystem, OneByZero works alongside Flow (AI study planner), Aura (mental wellness), and Vibe (audio learning) to support every aspect of a student's journey.
