SoDu is a Chinese-language novel search and reading portal that helps readers discover popular titles and find links to their latest chapters. Its catalog spans a broad range of genres, including fantasy, martial arts and cultivation, urban fiction, historical stories, detective fiction, online games, science fiction, horror, poetry, and other writing. Visitors can browse new additions and recent updates, explore popularity and click rankings, and view editor-recommended books and authors.

The site presents chapter links and reading access in a clean, ad-free format, with an emphasis on fast updates and a straightforward browsing experience. Registered members can use a personal bookshelf to collect novels and keep a record of books they have read, making it easier to return to their reading history. SoDu describes its role as providing links to recent novels from forums and book libraries rather than offering original publishing services.

It also invites rights holders to submit documentation concerning potentially infringing links for review and removal
