Bezel is a free retro game launcher that turns a collection of personally owned game files into a browsable library, with box art, descriptions, soundtrack themes, and support for more than 25 systems. Available for Windows, macOS, Linux, and Steam Deck, it offers both desktop and controller-friendly couch modes. Players can organize games, sync cloud saves, browse YouTube and Twitch, and use an on-screen translation overlay when playing imported titles. Bezel also supports ripping discs users own into playable files and recording game soundtracks from compatible emulators.

Its standout feature is Bezelie, an optional AI companion built into the launcher. Bezelie can watch gameplay, comment aloud, respond to conversation, remember past sessions, save highlights, and, in some situations, take control of a game. Users can customize her personality, appearance, voice, and talkativeness; deeper AI features are available through an optional subscription. Bezel describes itself as offline and private, while noting that some companion capabilities use vision and language models. The launcher is free, with game files supplied by the user.
