ABOUT
Built to give you a second pair of eyes
PixelTruth is a free, browser-native tool that tells you whether an image is a real photograph or a synthetic AI creation — instantly, privately, without sending your data anywhere.
The image you're looking at might not exist
In 2022, generating a photorealistic face required significant expertise and compute. Today it takes a sentence and three seconds. The gap between a photograph and a synthetic image has collapsed almost entirely. Your eyes alone are no longer a reliable instrument.
PixelTruth exists because the ability to verify what you are looking at is a fundamental information right — and it should not require a paid subscription, an account, or surrendering your images to a server you do not control.
Detection runs entirely inside a background Worker thread in your own browser tab. We do not have servers receiving your images. We could not see them even if we wanted to — and we do not want to. Your data is yours.
The RUNTIMEZERO principles
Every tool in the RuntimeHub network is built to the same standard. These are not aspirations — they are architectural constraints.
Architecture, not policy
We do not collect your data and then promise not to misuse it. We build the tool so collecting it is technically impossible. If a feature would require seeing your data, we run it client-side — or we do not build it.
Free means free — ads, not your data
RuntimeHub tools are free without limits. We sustain the network through contextual advertising via Google AdSense. Your images, behavior, and results are never sold or shared with advertisers.
No frameworks, no cruft
PixelTruth is built in vanilla HTML, CSS, and JavaScript. No React, no bundler, no heavy framework overhead. Fast to load, easy to audit, works on any modern browser.
Transparent about uncertainty
PixelTruth gives you a confidence score, not a verdict carved in stone. No detection system achieves 100% accuracy. The result communicates degrees of confidence — not a binary that overstates what the technology can deliver.

Nothing leaves your device. No uploads. No account. Just a private check inside your browser.
