Sonicert

What it is

Sonicert is a free web-based AI music detector that screens songs for signs of AI generation. Users upload MP3, WAV, M4A, FLAC or OGG files up to 50 MB or paste direct audio links, and the tool analyzes the first 300 seconds of audio to produce a spectral screening score or an inconclusive result when evidence is weak. The service requires no signup and permanently deletes audio immediately after analysis.

The detector recognizes output from major AI music generators and separates it from human-made recordings, including heavily-produced studio tracks. Results are reported as uncalibrated screening signals with confidence indicators, not as proof of authorship. The platform publishes its test results and methodology transparently, including failures and limitations.

Paid batch credit packs ($4.90 for 60 credits or $9.90 for 240 credits) add multi-track screening with resumable batches, per-item retry, and CSV export. API access for labels and platforms is in evaluation. Sonicert also offers specialized detectors for Suno, Udio, YuE2, and AI voices.

Questions from the bench

Is this AI music detector really free?

Yes. Single-track checks are free and unlimited with no account needed, using the same engine and scope for everyone. Paid batch credit packs starting at $4.90 add multi-track screening, per-item retry, and CSV export. API access for labels and platforms is in evaluation.

Does it work as a fully online AI music detector?

Yes. Everything runs online in your browser with no app, extension or installation needed. Users upload a file or paste a link on the page, analysis takes seconds, and the audio is permanently deleted right after.

What files and links can I check?

Users can upload MP3, WAV, M4A, FLAC or OGG files up to 50 MB, or paste direct audio links ending in those extensions. Files are permanently deleted after analysis. For tracks only available on Suno or YouTube, users should download the file first then upload it.

Do you store the songs I upload?

No. Audio is analyzed immediately and permanently deleted right after analysis, including transient copies in transfer storage. No library of uploads is built. With the optional batch workflow, each item is likewise dropped once it finishes, with a 24-hour cap on stray transfer copies and 30-day metadata retention.

Do you use my uploads to train AI models?

No. Audio is never used for training. Detection runs against the engine's existing reference fingerprints, and the file is discarded once the score is produced.
