Start with the file: AI music services often name themselves in the song's tags or add Content Credentials, which a tag reader like our AI song checker shows. For a song on a streaming service, Deezer marks fully AI-generated albums in its app, and its free AI music detector scans playlists from Spotify, Apple Music and other services for Suno and Udio tracks. For Google's Lyria, check for a SynthID watermark at synthid.com. If all of that comes back empty, look at the artist: AI acts often release far more often than a person could, with no live shows, credits or history.
1. Read the song file's own tags
If you have the file itself, start there. AI music services often write their name into the song's tags, in fields like the encoder, comment or website, and some add Content Credentials, a signed record of which tool made it.
Drop the song into our AI song checker. It reads MP3, WAV, M4A, FLAC and OGG files in your browser and flags any tag that names Suno, Udio, Stable Audio, Lyria, MusicGen or other AI music tools. A label is strong evidence, because services add them and people rarely add them by hand.
No label proves very little, though. Converting the file, uploading it to a streaming service or re-saving it in an audio editor usually drops the tags.
2. Check what the streaming service says
Deezer detects fully AI-generated music with its own system, which looks for traces that generators like Suno and Udio leave in the audio. It marks those albums for listeners in its app and keeps them out of its recommendations.
Deezer's free AI music detector, launched in June 2026, does the same check on your playlists from Spotify, Apple Music and about 20 other services. You connect your account and it lists the tracks it flags. It looks for fully AI-generated songs, so a track with an AI-generated backing but a human singer may pass.
3. Check for an audio watermark
Some AI music carries a watermark inside the sound. Google adds SynthID to music made with its Lyria models, and SynthID Detector checks uploaded audio for it. Our guide to SynthID explains what its results mean.
Suno has said it watermarks its songs too, and in August 2026 announced more watermarking and fingerprinting so distributors can identify its tracks. There's no public checker for Suno's mark yet.
4. Look at the artist, not just the song
When the file and the services come back empty, the artist page often answers the question:
- Release pace. Several albums a month, every month, is a pattern people can't keep up with.
- No life outside the streaming service. No shows, interviews, social accounts with real history or band members with names.
- Thin credits. No songwriter, producer or label beyond a distributor.
- The cover art. AI acts often use AI images. Download the cover and drop it into the AI image checker to see if it carries an AI label.
None of these prove anything alone. Three or four together are a strong sign.
5. Listen for AI clues, last
Listening clues still help sometimes: lyrics that are vague or repeat the title with no story, vocals whose breaths fall in odd places, consonants that blur, or an instrument that changes character halfway through a line. Current models are good enough that a song can pass on all of these, so use them as a reason to dig, never as a verdict.
What your results mean
| What you found | What it means |
|---|---|
| A tag or Content Credentials naming an AI tool | Almost certainly made with that tool |
| Deezer's AI tag or detector flags it | Very likely fully AI-generated |
| SynthID detected | Made or edited with Google's AI audio models |
| An artist with no history, a huge catalogue and AI cover art | Likely AI |
| Nothing found either way | Unknown. A missing label isn't proof a person made it |
Voice recordings work the same way. For a voice note or podcast clip, use the AI audio checker, which flags tags from voice tools like ElevenLabs.
