Was this song made with AI?
Drop in a song to see whether its own data says it was made with an AI music tool like Suno or Udio, and what else it carries about who made it.
Only the song'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 a song says it was made with AI, drop the MP3, WAV, M4A, FLAC or OGG file above. The checker reads its Content Credentials (C2PA), AI labels and tags such as the encoder, comment and website fields, and flags any that name an AI music tool like Suno, Udio or Stable Audio. It can't hear the music itself: if nothing is found, the song may still be AI-made, because tags are easy to remove.
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 wrote the file, which can be an AI music service |
| Comment, website and custom tags | Prompts, song links and notes that AI services often leave behind |
Tags that name a known AI music or voice tool, such as Suno, Udio, Stable Audio, Lyria, MusicGen, Mubert, AIVA, Soundraw or Boomy, are flagged as AI labels.
Why "no label" isn't proof
Tags and Content Credentials live beside the sound, not in it. Converting a song to another format, uploading it to a streaming or social site, or editing it in most audio apps can drop them. So a song with no label might still be AI-made. Our guide on how to tell if a song is AI-generated covers the other checks. A song with a label almost certainly came from that tool, because labels aren't added by accident.
Some companies also hide a watermark in the sound itself. Google adds SynthID to music made with Lyria; SynthID Detector checks for it. Our guide to SynthID explains how these watermarks work.
Other details in a song file
Songs can also carry the artist and composer names, recording dates, embedded cover art and, for phone recordings, the place they were made. The checker lists these too, so you can see what a file says about you before you share it. For voice notes and podcast clips, use the AI audio checker.
Questions, answered
Can this tell for certain if a song is AI-generated?
No tool can, from the file alone. This one reads what the file says about itself: Content Credentials, AI labels and the tags an AI music service leaves behind. If it finds one, the song very likely came from that tool. If it finds none, the song may still be AI-made, because tags are lost when a song is converted, re-uploaded or edited.
Do Suno and Udio songs carry a label?
Downloads from AI music services often name the service in the encoder, comment or website tags, and some add Content Credentials. These are easy to strip, and songs found on streaming sites or social media usually no longer have them.
What about watermarks hidden in the sound?
Some AI audio carries a watermark inside the sound itself, such as Google's SynthID in music made with Lyria. Reading file data can't detect it. Use Google's SynthID Detector for that.
Is my song uploaded?
No. The checker reads only the tag section of the file, in your browser, so even long WAV files work in a second and nothing leaves your device.
Which formats work?
MP3 (ID3 tags), WAV (INFO, BWF and Content Credentials), M4A and AAC in MP4, FLAC and OGG or Opus (Vorbis comments).
