Stageum

Stageum is a browser-based AI public speaking training platform that lets you rehearse presentations in photorealistic 3D environments, with no VR headset required. Powered by advanced WebGL and WebGPU technologies, it recreates real-world spaces such as boardrooms, auditoriums, and classrooms, complete with realistic virtual audiences that react to the speaker in real time, so every practice session feels like the real thing.

Using your webcam and microphone, Stageum's AI analyzes your speech patterns, body language, and gaze, then delivers instant, actionable feedback on filler words, pacing, eye contact, and vocal confidence. It also supports slide presentations and securely tracks detailed progress metrics over time, helping you see exactly how much you improve with every rehearsal.
