Cupfox, also known as 茶杯狐, is presented as a Chinese online search and aggregation platform for film and television content. Its stated aim is to make finding movies easier by bringing together entertainment listings from across the web, with options to watch films, television series, anime, and variety shows online. The site organizes its catalogue into sections for movies, dramas, short-form series, variety programs, and animation, and offers genre filters such as action, comedy, romance, science fiction, horror, documentaries, and suspense.

Visitors can browse featured and recently updated titles, view episode or release information, and keep a record of their viewing history. The listings span Chinese and international productions, including films, ongoing series, documentaries, and animated titles. The page also provides multiple viewing links, search suggestions, feedback options, and RSS access.
