Bypass Sightengine with SynthGuard
Sightengine moderates uploads on dating platforms, marketplaces, and KYC flows. SynthGuard's image humanizer makes AI-generated photos pass as authentic camera captures.
What Sightengine actually does
Sightengine offers AI image detection alongside nudity, violence, and brand-logo classifiers, used by dating apps, classifieds, and identity verification services.
Signals Sightengine scores
- Diffusion-model frequency signatures
- GAN fingerprints in face regions
- EXIF and color-profile inconsistencies
- Compression history mismatch
SynthGuard's counter-pipeline
- FFT disruption neutralizes frequency signatures
- Texture perturbation breaks GAN fingerprints
- Realistic EXIF + sRGB color profile
- JPEG double-compression layer simulates camera→export pipeline
Sightengine is the moderation layer behind a lot of services you've used without knowing. Dating apps use it to flag stolen or AI-generated profile photos. Marketplaces use it to detect listings with AI-generated product shots. KYC providers use it to spot AI-generated ID photos. Its AI detector specifically targets the frequency signatures of Stable Diffusion, Midjourney, DALL-E, and FLUX models.
SynthGuard's image humanizer counters this with a multi-layer pipeline. The FFT disruption layer adds controlled noise in the exact frequency bands where diffusion models leave fingerprints. The texture perturbation layer adds microvariance in skin and fabric regions where GAN fingerprints typically concentrate.
Compression history is a less-known signal. Real camera photos have a characteristic compression chain: sensor → camera JPEG → upload re-compression. AI images are usually saved as PNG or single-pass JPEG, which is itself suspicious. The JPEG double-compression layer in SynthGuard simulates the full chain at appropriate quality levels.
For dating profiles specifically, also strip the EXIF GPS and use a realistic timestamp from the past few days. SynthGuard's EXIF generator handles all of this with one toggle.
Browser-only means your photos never touch a server. There's no risk of leakage from the humanizer itself — the only people who ever see your image are the ones you upload it to.

Will my dating profile photo pass after humanization?+
Sightengine's AI flag will not fire on a properly humanized image. Other flags (face match, nudity) are independent.
Can Sightengine detect double-compression?+
Yes — but real camera photos have it too, which is why we add it back to AI images.
Does this work on Midjourney v6 outputs?+
Yes — the FFT layer parameters cover Midjourney v5/v6, SD 1.5/2/XL/3, FLUX, and DALL-E 3.
Is humanization legal for dating apps?+
Most dating apps require photos to be of the actual user. AI-generated dating photos may violate ToS regardless of detection.
