I Spy AI

Drop in a profile picture, dating app photo, or any suspect JPEG, PNG, or WebP and I Spy AI returns an authenticity score with a detailed analysis.

I Spy AI is an AI image detector that looks for AI fingerprints, synthetic faces, and deepfake patterns, so you can check a match, seller, influencer, or stranger before you message them, meet them, or send money.

Developers get a second route.

I Spy AI runs an MCP server that connects to agents such as Claude and Cursor, which lets you filter synthetic images out of automated validation pipelines or clean training datasets without reviewing each file by hand.

Journalists and researchers can run the same checks on viral images and source material.

The service is free and says it needs no credit card.

The site also states that uploads are encrypted and images are not stored after analysis.
