Features

Built for the
skeptical scroller.

Detection
Heuristic + ML analysis

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

Speed
Seconds

Analysis is powered by Google's Gemini API and returns in seconds. Your image is processed and immediately discarded — no storage, no logging, just a verdict.

Privacy
Analyzed, never stored

When you scan an image, it's sent to Google's Gemini API for analysis and immediately discarded — by both Google and CYPHR. We never store, view, or share what you scan. The only data we keep is your scan count, for billing.

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.

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? +
Yes — and we want to be transparent about it. When you scan an image, it is sent to Google's Gemini API for analysis. The result is returned to your browser and the image is immediately discarded by both Google and CYPHR.

Google's Gemini API does not use your data to train its models — data sharing is strictly opt-in, and CYPHR has not opted in. Google may retain API inputs for up to 55 days for abuse monitoring, disconnected from your account or identity. CYPHR never stores, logs, or has access to what you scan. See our Privacy Policy for full details.
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 Ultra was built with journalists and investigators 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

Transparent by design.
Private by default.

Gemini API, not your device

Each scan is processed by Google's Gemini API — a paid developer API with strict data terms. Your image travels to Google's servers for analysis and is immediately discarded. Neither Google nor CYPHR stores what you scan.

No image storage, ever

CYPHR never stores your images or what's in them. Scan verdicts in your history (Pro / Ultra) record only the result — never the image itself. Close the popup and the image is gone.

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.
