CYPHR
AI Image Detector

Stop guessing.
Start knowing.

CYPHR is a Chrome extension that quietly examines any image on the web and tells you whether it's AI generated. No hype. No alarms. Just a verdict.

How it works

Three steps.
One verdict.

No accounts. No configuration. CYPHR works the moment it's installed.

01
Install the extension

One click from the Chrome Web Store. CYPHR sits quietly in your toolbar until you need it.

02
Right-click any image

See an image you're not sure about? Right-click it and select "Scan with CYPHR."

03
Read the verdict

A confidence score, the telltale signs detected, and a receipt you can copy and share, all in under 10 seconds.

Features

Built for the
skeptical scroller.

Everything designed around one question: is this image AI?

Detection
Heuristic + ML analysis

Combines frequency-domain analysis, metadata inspection, and diffusion model pattern recognition into a single confidence score.

Speed
Seconds

Analysis runs right on your screen. No round-trips to a server means results appear before you've even read the headline.

Privacy
Your images never leave your device

What you do with CYPHR stays between you and your browser and is deleted immediately afterwards. We do not store, share, retain, index or use your images for any other purpose including model training.

Coverage
Works on any website

News sites, social feeds, marketplaces, forums. If a browser can render it, CYPHR can scan it. Video and text capabilities coming soon!

Transparency
Signals, not just scores

CYPHR describes exactly what it found: missing EXIF data, noise profile anomalies, diffusion artifacts in the frequency spectrum.

Portability
Copy & share the report

One-click report copy. Paste a structured verdict anywhere — in a reply, a document, a Slack thread. Help family, friends, and colleagues navigate the digital world.

Live detector

This is CYPHR's detection engine, running right here on the page. Drop any image into the panel and we'll analyze it for signs of AI generation. Same as the Chrome extension!

FAQ

Common questions.

Anything else? We'd love to hear from you at hello@getcyphr.com

How accurate is CYPHR's detection? +
CYPHR achieves 97.4% accuracy on our standard benchmark set of 10,000 images. This covers output from Midjourney, DALL-E 3, Stable Diffusion, Firefly, and Imagen. Real-world accuracy depends on image quality and post-processing — heavily compressed or cropped images may score with lower confidence.
Does CYPHR upload my images to a server? +
No. All analysis runs on-device using a locally-cached model. The image bytes never leave your browser. CYPHR does not have a backend that receives, logs, or stores image data.
Can CYPHR detect images that have been edited after generation? +
Yes, with reduced confidence. Post-processing like cropping, filtering, and JPEG re-compression can obscure some signals, but diffusion artifacts in texture and frequency domains are often persistent. CYPHR reports its confidence level — treat low-confidence scans as inconclusive, not as a verdict.
Which browsers does CYPHR support? +
Chrome and Chromium-based browsers including Edge, Brave, and Arc. Firefox and Safari support is planned for a future release.
What does the confidence score mean? +
The score represents CYPHR's certainty in its verdict — not the percentage likelihood that an image is AI-generated. A 97% authentic verdict means CYPHR is 97% confident the image is real. A 72% AI verdict means the signals are present but not fully conclusive.
Can I use CYPHR for professional or journalistic work? +
Yes, and we encourage it. CYPHR Pro was built with journalists and researchers in mind. The shareable report format is designed to be citable. That said, CYPHR is a screening tool — it should support editorial judgment, not replace it.
Privacy

We see what you see.
Nothing more.

CYPHR's privacy model is simple: we built it so we couldn't spy on you even if we wanted to.

On-device inference

The detection model runs entirely inside your browser. Image data is processed locally and never transmitted to any server.

No scan history (Free)

On the free plan, scan results are never logged. Close the popup and they're gone. Pro users can opt into local history stored only in their browser.

Minimal permissions

CYPHR requests only the permissions it needs: access to image URLs on the current tab when you explicitly trigger a scan. No broad host permissions.
