SoDu is a Chinese-language novel search and reading website that helps readers discover novels and access links to their latest chapters. Its catalogue spans genres including fantasy and magic, wuxia and cultivation, urban fiction, historical fiction, detective stories, online gaming, science fiction, horror, poetry, and other categories. Visitors can browse popular titles, recently updated works, new additions, author recommendations, and rankings based on clicks, overall popularity, and collections.

The site describes its pages as ad-free, uncluttered, and frequently updated, aiming to make online reading straightforward. Registered members can use a personal bookshelf to save favourite novels and keep a record of their reading history, making it easier to return to previously viewed stories. SoDu states that it operates as a novel search engine, providing links to current works from novel forums and libraries rather than presenting itself as the publisher of those titles.

It also invites copyright holders to submit supporting documentation so that disputed links can be removed
