AI Image Detector

Check whether an image looks AI-generated. The image never leaves your browser.

Private, browser-only detection

Selected images are decoded and processed in your browser. Nothing is uploaded to any server.

Each batch first checks embedded metadata (instant). If metadata cannot decide, a local ONNX model scans the pixels — your browser downloads it once (≈172 MB), then caches it for later visits.

Two layers of evidence

How AI image detection works

We start with the strongest clues available, then use a local visual model only when the file’s metadata cannot decide.

One or many images
01

Instant check

Read the file’s story

We inspect EXIF, XMP, PNG text fields, and Content Credentials such as C2PA. Generator names, prompts, and workflow data can provide a strong provenance signal.

No model download needed when metadata decides
02

When needed

Study the pixels

A small browser model examines the image for visual patterns learned from real and generated examples. It returns a cautious estimate, never a proof.

One-time 172 MB model download

Private from start to finish

Your files, metadata, and results stay in your browser. Nothing is uploaded to PicSmash.

Built for batches

Select a single image, multiple images, or a complete folder. Every file gets its own result.
