Spot Slop

Was it made by a person?

In development

Spot Slop looks at a track and tells you whether it was made by a person or generated by AI — as a probability with a confidence range, not a one-word guess, and with the evidence behind it.

Paste a link from a streaming service, or upload a file. It checks the track's provenance first, and listens to the audio when provenance can't answer.

What it will and won't claim

A calibrated estimate, with a range — so you can see how sure it is.
Its reasoning: the catalog match, the era, what the audio model heard.
Never proof. Results are probabilistic, and it says so plainly.
No accusations. An unclear answer stays unclear rather than picking a side.
