It offers a variety of learning elements such as video lectures, books and sheets, links of contents, a bank of answered and unanswered questions, and a testing engine. The application is structured into different categories based on educational stages and countries for public education, and main and subcategories for higher education and professional certificates.

One of the unique features of Manahij is that it allows members to contribute to the application by inserting new subjects and proposing scientific materials from YouTube that support concerned courses. The application also provides a feature for teachers to design quizzes for their students and control their designated quiz by determining its availability to all users or only to their students.

Manahij also considers the process of supervision and academic follow-up, providing notices to parents, class supervisors, and subject supervisors whenever the student watches a lecture, reads a book or content link, or submits quizzes. Furthermore, Manahij encourages users to interact and share their knowledge and experiences by answering questions submitted by other members.

Overall, Manahij is an excellent education and reference application that promotes lifelong learning, continuing education, and evaluation of knowledge gained by its users.
