Ghibli-Style Detector
The wave of Ghibli-style generated images made something visible that had been abstract until then: a studio's distinctive look, developed over decades, reproduced by anyone in seconds. Whatever you think of that, it created a practical need to tell one from the other.
Style imitation, and why it is hard to check
Everything that makes this style beautiful also removes the evidence detection normally relies on.
Flat colour removes the evidence
Hand-painted animation backgrounds and clean cel colour carry no sensor noise and little texture variation. Several forensic methods have almost nothing to measure.
Brushwork without direction
Painted backgrounds in the original style have visible, directional strokes following form. Generated imitation produces statistically uniform texture that reads as painterly without being painted.
Detail distributed evenly
Animation art directs attention deliberately — detail where the eye should go, simplification elsewhere. Generated versions hold the same density across the whole frame.
Architecture and machinery
The original style is famous for mechanical and architectural coherence: things that could actually work. Generated imitation produces buildings and machines that look right and could not function.
Character consistency
Across several images of the same 'character', proportions drift subtly. Animation production sheets exist precisely to prevent that.
No production trail
Real animation art comes with layers, keys and production history. Generated images arrive flat with no working files behind them.
How the analysis works
Upload the original file
Full resolution, straight from the source. Screenshots and re-saved copies destroy most of the evidence we measure.
12 independent methods run in parallel
Three neural networks look at the image as a whole. Nine forensic methods examine it as a signal: frequency (FFT) analysis, noise pattern, pixel-level statistics, EXIF metadata, Error Level Analysis, texture coherence, colour distribution, Benford's Law and edge detection.
You see the breakdown, not just a number
Every method reports separately, so you can tell whether the verdict rests on one weak signal or on nine that agree.
For photographs rather than stylised art, start with our AI image detector — it covers any image type and runs the same twelve methods.
How much each method counts
Most detectors give you one number from one model. We run twelve independent analyzers and weight them — three neural networks carry the majority, but nine forensic methods examine the file as a signal and can overrule them. Here is the exact weighting we use in production:
| Method | Weight in final score |
|---|---|
| Neural network #2 | 25% |
| Neural network #1 | 15% |
| Neural network #3 | 15% |
| EXIF metadata | 10% |
| Frequency (FFT) | 6% |
| Benford's Law | 6% |
| Noise pattern | 5% |
| Error Level Analysis | 4% |
| Texture coherence | 4% |
| Edge detection | 4% |
| Pixel statistics | 3% |
| Colour distribution | 3% |
What people actually upload
These are our own numbers, not an industry estimate — every check run through FakeSec since launch. The split is closer than most people expect: roughly four in ten uploads really do turn out to be generated.
Where it comes up
- Artists — Work in a similar style being accused of generation.
- Print and merch sellers — Marketplaces restricting generated content.
- Commission clients — Paying for original illustration in a style.
- Rights holders — Material circulating with implied studio association.
Accuracy — and where it breaks down
On our internal benchmark of 240,000 images (120,000 AI-generated, 120,000 real) the combined score reaches up to 98% on unedited, full-resolution files. That number drops, sometimes sharply, in four situations — and you should know them before trusting any result:
- Heavy compression. Social platforms re-encode everything. A photo pulled from Instagram has already lost much of its noise signature.
- Screenshots. A screenshot is a new image of an image. Original metadata and compression history are gone.
- Stylised content. Flat colour and clean lines remove the texture and noise evidence forensic methods depend on.
- Post-processing. Added grain, filters, upscaling and manual retouching all mask generation traces.
No detector on the market is 100% accurate — ours included. Treat a high score as strong evidence, not as proof. When a decision matters, look at which of the 12 methods agreed.
This is the hardest category we handle, and pretending otherwise would be dishonest. Flat stylised art gives forensic methods little to work with, so expect lower confidence and treat process evidence — layers, sketches, timelapse — as the stronger proof.
