FlexAi
FlexAi
Watch your own Plex library on the big screen, from the couch, with one app that feels at home on every Apple device.
FlexAi runs as a full-screen “10-foot” app on a Mac connected to a TV, as a native Apple TV app, and as an iPhone app, all from one Swift and SwiftUI codebase. It started as a web-based Plex player with AI search and was rebuilt from scratch as native Apple apps, with a cleaner, safer way to sign in.





FlexAi is an independent app and is not affiliated with Plex. Movie and show artwork belongs to its owners.
