We have often wanted to learn about some topic, but there was no place where you would find the best resources. Your only option was to hit Google Search where resources are not sorted by quality. Hence we created free platform where anyone can register links to learning resources (videos, books, websites, etc.), organize them by topics and rate them, so that the best ones can be found by others seeking knowledge in a specific area. Resources are also sorted by their difficulty, so you find fitting resources no matter whether you are a beginner or an expert. There is also a system of "edit requests" and reputation, so that anyone can contribute to the public database.
