Sodu is a Chinese-language online novel search and discovery platform designed to help readers find fiction across a wide range of genres. Its catalogue covers fantasy, martial arts and cultivation, urban stories, historical fiction, detective and mystery, online gaming, science fiction, horror, poetry, and other categories. Readers can browse popular titles, recently updated books, new additions, author listings, recommendation rankings, and click-based charts, or search for novels and follow links to the latest chapters.

The site describes its role as providing links to new novels from various online forums and digital libraries, rather than presenting itself as a publisher. It promotes quick updates, an uncluttered reading experience, and pages without advertising or pop-up windows. Registered members can use a personal bookshelf to save titles and access reading history, making it easier to return to previously viewed books.

Sodu also offers mobile reading access and a traditional Chinese interface option. For copyright concerns, the site says users can submit supporting documentation by email to request removal of a link
