Could this be true?

AI detection that shows its work. Paste text, drop an image — we surface the artifacts. ELA, FFT spectrum, channel decomposition, noise residuals, C2PA provenance. Not a black-box score. The evidence.

How it works

Six signals, one verdict

Every check runs an ensemble of forensic techniques. Each one produces a visualization you can inspect — so you always know why something was flagged.

  • Error Level Analysis

    ELA

    Re-saves the image at known JPEG quality and measures compression delta. Splices and edits glow.

  • FFT Spectrum

    FFT

    Fourier transform reveals periodic artifacts left by GANs and diffusion samplers — invisible to the eye, loud in frequency.

  • RGB

    Channel Decomposition

    RGB / YCbCr

    Splits the image into color channels. AI generators leak color statistics that don't match real cameras.

  • Noise Residual

    PRNU

    Real cameras leave a unique sensor-noise fingerprint. AI images either lack one or have a learned, repetitive one.

  • Saliency Heatmap

    Grad-CAM

    Where is the detector model paying attention? Heatmap shows the regions driving the verdict.

    C2PA Provenance

    Cryptographic

    Reads tamper-evident signatures from Adobe, OpenAI, Sony, BBC content. When present, this beats every other signal.

Why we're different

Most detectors give you a number. We give you the receipts.

Originality, GPTZero, Hive — every major AI detector outputs a single confidence score: “87% AI.” You're asked to trust a black box. We don't do that.

We expose the entire forensic pipeline. Every signal is visualized, every decision is auditable. Combined evidence beats any single classifier — and harder to evade than one.

Multi-signal ensemble

Six forensic checks run in parallel. One fails, others catch it.

Visual evidence

Every signal renders to a heatmap, spectrum, or channel split you can inspect.

C2PA-aware

Reads cryptographic provenance from Adobe, OpenAI, Sony, and BBC content.

Cheap, fast, private

Most checks run in your browser. Nothing uploaded unless you ask.
