Greyled is a web‑based learning platform that aggregates open educational resources (OER) into a searchable library, giving students free access to textbooks, homework, grades, and progress tracking. Professors can author, customize, and publish their own open textbooks and interactive assignments, which are seamlessly integrated with the same system, and students pay a modest per‑class fee for access to professor‑run courses.

Problem
Students in higher education often face prohibitive costs for textbooks, while educators lack flexible tools to create, adapt, and share open educational resources (OER) within a unified learning environment.
Solution
Greyled provides a web-based platform that aggregates OER textbooks into a searchable library accessible to all students at no cost. Professors can author, customize, and publish their own textbooks and associated interactive activities, which are then linked to the same platform. The system integrates coursework, homework, grading, and progress tracking, allowing students to study, complete assignments, and view feedback without needing separate tools. By removing paywalls and offering a collaborative authoring workflow, Greyled reduces financial barriers and streamlines the teaching‑learning cycle in higher education.
