Stop the endless scrolling. Swipe cards, train an AI that learns your taste, and find tonight’s film in seconds.


Every swipe teaches it something new. The more you use it, the sharper its recommendations get — an engine that learns from you, not generic lists that fit anyone.

Tell us what you subscribe to and Cetra only recommends what you can already watch. And when you pick a title, you open it straight on the platform where it lives, with no hopping between apps.

Save what you mean to watch, mark what you like and dismiss what you don’t. And we tell you when something on your watchlist lands on your platforms or gets a new season.

Only 90 minutes before bed? Something from the 80s with a good score? Filter by runtime, year, genre, age rating and minimum score. And check your history to recover that title you let go.
Create a room, share the code with your partner or your friends, and everyone swipes from their own phone. When you land on the same title… Match! The evening is saved.
Create a room and share the link or the code.
Everyone swipes cards from their own phone.
When you agree, the match pops up. Film time.
