Check if audio was made with AI
Drop in a voice note, podcast clip or sound file to see whether its own data says an AI voice tool made it, and what it reveals about where it was recorded.
Only the file's tags are read, in your browser. The audio is never uploaded.Checking is free. Cleaning is part of Pro, from $2 a month, and your first clean each day is free. About Pro- 1Add your file

How it works
To check whether an audio file says it was made with AI, drop it above. The checker reads its Content Credentials (C2PA), AI labels and tags, and flags any that name an AI voice or audio tool such as ElevenLabs, Play.ht, Murf or Speechify. It also shows the recording location, device and dates. It can't analyse the voice itself; for that, use ElevenLabs' AI Speech Classifier or a dedicated deepfake detector.
What the checker looks for
| Where | What it can say |
|---|---|
| Content Credentials (C2PA) | A signed record naming the tool and whether AI generated the audio |
| AI label (IPTC, in XMP) | trainedAlgorithmicMedia, the standard code for "made by AI" |
| Encoder and software tags | The app that made the file, which can be an AI voice service |
| Recorder data | Location, device and recording time from phones and field recorders |
Tags that name a known AI voice or audio tool, such as ElevenLabs, Play.ht, Murf, Speechify, Resemble AI or WellSaid, are flagged as AI labels.
What a missing label means
Labels sit beside the sound, not inside it. Re-recording, converting or sharing through a messaging or social app usually drops them. So a clip with no label might still be AI-made, while a clip with a label almost certainly came from that tool.
For a second opinion on a voice, use ElevenLabs' AI Speech Classifier for audio made with its tools, and SynthID Detector for audio made with Google's models. For songs, see the AI song checker.
Questions, answered
Can I tell if a voice is a deepfake?
Not from the file's data alone. This checker shows whether the file labels itself as AI-made or names an AI voice tool. To test the voice itself, ElevenLabs offers a free AI Speech Classifier for audio made with its tools. A missing label doesn't mean the voice is real.
Does ElevenLabs label its audio?
ElevenLabs says it adds Content Credentials to audio it generates, and downloads can name it in their tags. Both disappear when the audio is converted, re-recorded or posted on most social apps.
Do voice memos contain my location?
iPhone Voice Memos and some recorder apps save the recording's place name or GPS position and the device in the file. Drop a recording in to see what yours contains before you send it.
Is my recording uploaded?
No. Only the tag section of the file is read, in your browser. Nothing is sent anywhere.
Which formats work?
MP3, WAV, M4A and AAC, FLAC, and OGG or Opus files. Only the tags at the start or end of the file are read, so long recordings and large WAV files work just as quickly as short clips.
Clean Word, PDF, video and audio files too
Pro removes hidden data from documents, videos and audio, and cleans whole folders at once. From $2 a month, billed yearly, and your first clean each day is free.
