SoDu, also known as Sodu Novel Search, is an online Chinese-language platform for discovering and reading novels. It organizes titles across genres including fantasy, martial arts, urban fiction, historical fiction, detective stories, online gaming, science fiction, horror, and poetry. Readers can browse popular and recently updated books, check rankings, explore new additions, and view recommended titles and authors.

The site describes its search and reading experience as fast, uncluttered, and free of advertising and pop-up windows, with links to the latest chapters collected from novel forums and libraries. Registered members can use a personal bookshelf to save titles and access reading history, making it easier to return to books they have viewed or collected. SoDu also offers mobile reading and language-version options.

It functions as a novel search and discovery service, providing links to external sources rather than presenting itself as the publisher of the books. The site invites copyright holders to report infringing links for removal
