Why AI-generated photos need a detector — not just a sharp eye

A 2025 Microsoft study found that humans correctly identify AI-generated photos only 61% of the time. That's barely better than guessing. Modern AI generators like Midjourney v6, SDXL, and DALL-E 3 produce faces with natural skin texture, realistic lighting, and convincing detail that fools even experienced eyes.

Worse: reverse image search is useless against AI-generated faces. There's no original photo to match against — the face never existed, so no database contains it. The only reliable check is pixel-level pattern analysis: AI generators leave subtle artifacts in image noise and frequency patterns that are invisible to humans but detectable by machine learning models trained to find them.

That's what Faux Spy does. Every scan runs through a detection ensemble that finds those patterns in seconds, across any image on any website — without you having to know what to look for.

Also available on Chrome, Brave, Edge, and Opera.

Same detection, same pricing — works across all Chromium browsers.

Where can I find Faux Spy on addons.mozilla.org?+

The listing is live at addons.mozilla.org/addon/faux-spy-ai-image-detector/. Click "Add to Firefox" on that page to install instantly.

Does the Firefox version have the same features as Chrome?+

Yes. The Firefox add-on is built from the same codebase as the Chrome extension with Firefox-specific compatibility adjustments. All detection features, the case file history (Pro), share menu, and pricing tiers are identical. The main difference: the Firefox version uses cloud AI detection only (no local pre-filter model), which means every scan makes a network call and takes 1–3 seconds.
