Engineered formeasurable signal control
SynthGuard adjusts selected camera-style characteristics across multiple measurable signals, without claiming that an export proves camera origin or predicts a private detector or platform.
Sensor Noise & PRNU
We add a camera-style CMOS noise profile—one of several forensic signals some image detectors inspect.
FFT & Watermark Disruption
Frequency-domain edits adjust selected periodic and watermark-related signals. Verifier outcomes are not guaranteed.
Authentic Camera EXIF
40+ real device profiles - iPhone 15 Pro, Sony a7, Canon R5 - with matching ISO, aperture and GPS jitter.
10 layers,processed locally.
The image pipeline uses TypeScript, Canvas and a Web Worker in your browser. Seven signal-facing passes stay visible in the trace while three refinement stages remain abstracted. Image content is not uploaded for processing; account and quota metadata may still be recorded.
A workflow built forcreators & operators
We rebuilt the post-production pipeline from scratch — for the people who actually ship AI content every day, not for research labs.
Generate
Run your usual model — Midjourney, SDXL, Flux. Output anything you want at any aspect ratio.
Humanize
Drop the batch into SynthGuard. The 10-layer pipeline rewrites every statistical fingerprint locally.
Publish
Inspect the export, preserve required disclosures and follow the current rules of the platform where you publish.
Four tools,clear privacy boundaries.
Images, video and detector scans run locally. Text Light mode is local, while Standard and Aggressive use the disclosed inference route for deeper rewriting.
Photo Humanizer
10-layer local image pipeline with camera-style noise, frequency refinement, coherent EXIF and provenance-signal review.

Eight forensic signals fused into one verdict — noise, JPEG grid, FFT, EXIF and more. Free, browser-only.

Test before you post. The same statistical signals platforms use to flag synthetic media - now in your hands, before they ever get the chance.
Publishing rules areplatform-specific
Platforms combine labels, disclosure systems, content policies and moderation processes. No third-party detector can predict reach, monetization or account action.
Applies AI labels and integrity policies; reach also depends on content quality, disclosure, behavior and policy compliance.
TikTok
Requires labels for realistic AI-generated content and says using the disclosure setting alone does not reduce distribution for compliant posts.
Twitter / X
Synthetic media remains subject to platform rules, user context and monetization policies; outcomes are not predicted by one detector score.
Marketplaces
Listing, originality, disclosure and intellectual-property requirements vary by marketplace and product category.
Why creators chooseSynthGuard
A privacy-first humanizer focused on real-camera fidelity, sub-5-second processing and zero data exposure - built for the operators who ship every day.
10-LAYER PIPELINE
Seven public layers cover sensor, frequency, texture, color and compression traces. Three internal refinement passes stay reserved.
LOCAL MEDIA
Images use TypeScript, Canvas and Web Workers; video uses ffmpeg.wasm. Text Light mode is local, with deeper modes disclosed separately.
REAL CAMERA EXIF
40+ device profiles with physically consistent ISO, aperture, focal length, GPS jitter and timestamp chains.
DETECTOR INCLUDED
Verify before you post. The same v2 detector engine the platforms use, free with every plan.
Voices ofSynthGuard operators
Hear from the agencies and creators who built SynthGuard into their daily publishing workflow — and stopped losing accounts.
"Finally, a humanizer that understands modern publishing pipelines. The browser-only architecture fits straight into our workflow, and the built-in detector lets us check every asset before it ships."
