Tucao, also known as the “Tucao Danmu” or “Tucao Bullet Comment” site, is a Chinese video-sharing and streaming platform established in 2011. It focuses primarily on animation and anime, while also offering television dramas, films, variety entertainment, music, games, and other video content. Its catalogue includes current seasonal series, ongoing shows, completed titles, theatrical releases, Chinese-produced animation, and selected live-action programs.

Users can browse recommendations, rankings, schedules, and programme collections, with video pages featuring viewer comments displayed as on-screen bullet comments. The site also provides mobile and TV applications. According to its site information, the Android app supports features such as favourites, comments, offline caching, accounts, and rankings; an iOS version offers caching and many desktop-style functions, while the TV version is designed mainly for viewing and does not include login or registration.
