SoDu is an online Chinese-language novel search and reading platform that helps readers find recent chapters from novels across a range of genres. Its catalogue spans fantasy and magic, martial arts and cultivation, urban fiction, historical fiction, detective stories, online gaming, science fiction, horror, poetry, and other categories. The site features popular and frequently updated titles, along with rankings for daily and overall clicks, new additions, recent updates, collections, authors, and recommendations.

SoDu promotes a fast-updating experience with clean pages and no advertisements or pop-up ads. Registered members can use a personal bookshelf to save titles, manage collections, and view reading history, making it easier to return to books and resume reading. The site describes itself as a search engine that provides links to novels hosted by forums and book libraries, rather than presenting itself as the publisher of those works.

It also invites copyright holders to submit documentation so that links alleged to infringe rights can be removed
