Human or AI?

Human or AI? is an audio analysis tool that identifies whether a spoken voice belongs to a human or an artificial intelligence.

Voice Check listens to playing audio and determines whether a voice is human or artificial as it speaks. It runs locally in the browser or via a macOS app called Off the Record, ensuring audio stays on the user device without leaving recordings. The interface displays the last minute of audio readings color-coded in green for human and red for AI. It works across languages by analyzing voice sound rather than content. Developers can also integrate the underlying models via API or local server deployment.
