Audio and video made on VoxNeura carry a hidden watermark — inaudible in speech, invisible in picture — that survives editing and re-encoding. Upload a file and we'll tell you whether we can find it. Your file is deleted the moment the check finishes.
Drop an audio or video file, or click to choose
MP3, WAV, M4A, MP4, MOV and similar
A negative result is not proof of anything. We can only detect our own watermark. A file with no watermark may still be AI-generated, by us or by anyone else.
Heavy re-encoding, a very short clip, or a recording of a recording can all erase a mark that was once there.
