SoDu is an online Chinese-language novel search engine and reading platform that helps readers discover novels and access links to their latest chapters. Its catalog spans a broad range of genres, including fantasy and magic, martial arts and cultivation, urban fiction, historical stories, detective and mystery, online gaming, science fiction, horror, poetry, and other categories. Readers can browse popular titles, recently updated works, new additions, author recommendations, and ranking lists based on clicks or collections.

The site emphasizes fast updates, a clean reading experience, and pages without advertising or pop-up interruptions. Registered members can use a personal bookshelf to collect novels and keep a history of books they have read, making it easier to return to a story and follow new chapters. SoDu describes its role as providing links to recent novels from various fiction forums and online libraries; it does not present itself as the publisher of those works.

The platform also invites copyright holders to report infringing links for removal
