FlexAi

A fast, good-looking Plex player for Mac, Apple TV and iPhone
Mac Apple TV iPhone In TestFlight

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.
