YarKetab is an Iranian online platform for organizing and joining book-reading competitions. Launched in October 2016 as a centralized competition service, it aims to make events easier to discover and access, reduce the costs of promotion and administration, and enable individuals to create competitions quickly. Users can browse active contests, register to participate, and access the specified reading materials.

The platform presents reading competitions as both a chance to win prizes and an opportunity to gain knowledge. Organizers can set up contests without charge, while participation fees vary by event; after a contest closes, winners are selected through a draw according to its rules. YarKetab also publishes competition results, offers certificate verification, and provides frequently asked questions and membership services.

Its listings feature events created by a range of organizers, including cultural associations, public libraries, universities, and individual users. The site further shares articles and announcements about reading competitions and book-related campaigns, helping readers find opportunities centered on books, learning, and cultural topics
