Make AI Undetectable— images, videos & text.
A cross-tool hub for adjusting image, video and text characteristics. Media processing stays local; text privacy varies by mode, and no detector or platform result is guaranteed.
One score is not the whole picture. Compliance still matters.
Platforms combine their own policies, disclosure systems and moderation processes. A third-party detector cannot predict reach, labeling or account action.
Platform policy changes
Synthetic-media labels, disclosure duties and moderation rules vary by platform and can change without matching a third-party detector score.
Forced AI labels
Meta and TikTok can use provenance indicators and creator disclosure to add AI context. A label is not the same as a published universal reach penalty.
Commercial policy risk
Creator platforms can require identity, consent, rights and disclosure checks. Review the current rules before publishing or monetizing content.
Account enforcement
Violating platform terms can lead to labels, removals or account action. File processing does not replace compliance or required disclosure.
The undetectable stack
Three tools. One mission. Built for transparent signal adjustment.
Compare measurable characteristics, preserve meaning and visual quality, and review the current publishing rules.
01 / IMAGES
Make AI Images Undetectable
Adjust frequency, noise, color, compression and metadata characteristics locally. Compare the result with the built-in detector, without treating one score as proof of origin.
- 10-layer browser pipeline
- Real-camera EXIF (40+ devices)
- C2PA-aware re-encoding
- Eight-signal local comparison
02 / VIDEOS
Make AI Videos Undetectable
Frame-by-frame humanization for Sora, Runway, Kling, Pika and Veo outputs. Re-encoded with realistic codec noise, container metadata stripped, motion fingerprints disrupted.
- Per-frame sensor noise
- Container metadata wiped
- Codec & bitrate naturalised
- No detector outcome guarantee
03 / TEXT
Make AI Texts Undetectable
Adjust rhythm, phrasing and sentence cadence while preserving meaning. Light mode is local; Standard and Aggressive use the disclosed inference route.
- Detector-aware writing metrics
- No fixed-score promise
- Tone preserved, meaning intact
- EN + DE auto-detect
Your face is your brand. Your AI workflow shouldn't kill it.
OFM agencies and solo creators run on volume — DM funnels, daily promo, custom content, mass-market PPV. AI lets you scale that volume 10× — but only if the content reads real to platforms, subscribers and the bots that scrape your feed at 3 AM.
SynthGuard humanizes every asset in your funnel — promo on IG & TikTok, teaser clips for Reddit and X, custom photo sets and video DMs — so platforms don't flag, subscribers don't churn, and your conversion stays clean.
Subs trust real
Adult subscribers pay for parasocial connection. The instant they suspect AI, churn spikes and refund requests follow. Authentic-looking media protects LTV.
Review distribution risk
Distribution depends on content quality, audience response and current platform rules. No processing tool can promise reach or prevent enforcement.
Measurable media signals
Camera-style EXIF, compression and noise let you compare concrete forensic characteristics without claiming the export proves camera origin.
Mode-specific privacy
Image and video content is processed locally. Text Light mode is local; Standard and Aggressive use the disclosed inference route. Account and quota metadata may be recorded.
How it runs
Drop. Humanize. Verify. Publish.
The same four steps for every asset type — and the entire flow stays inside your browser tab.
Choose
Select image, video or text and review the privacy boundary shown for that tool and mode.
Humanize
Media processing runs locally; text Light runs locally while deeper text modes use the disclosed inference route.
Inspect
Compare image exports with the free local detector. Its eight-signal verdict is diagnostic, not proof of origin.
Review
Check quality, rights, provenance and the current disclosure rules before publishing.

Why SynthGuard
Built like a forensic tool. Priced like a subscription.
Zero upload, ever
Web Worker pipelines on your device. Disable your network and humanization still runs. We physically cannot leak what we never receive.
Forensic engineering
PRNU sensor synthesis, FFT band scrambling, EXIF reconstruction, burstiness restoration — built by detection engineers, not prompt-stackers.
Continuous detector recalibration
Weekly bench against GPTZero, Originality, Turnitin, Hive, Sightengine, Optic, Illuminarty and AI-or-Not. When detectors update, our pipeline updates the same week.
Tone & quality preserved
Sub-2-LSB amplitudes for images. Meaning-preserving rewrites for text. Per-frame consistency for video. Authenticity without quality loss.
Detector + Humanizer in one
Every plan includes the free in-browser AI Image Detector. Verify before you publish — eight forensic signals, instant verdict.
Fair-use credits, no rug pulls
Transparent weekly credit model. Free tier for casual creators, Pro for power users, Studio for agencies — no surprise rate-limits.
FAQ
The questions creators actually ask.
Will this actually beat GPTZero, Originality, Turnitin, Hive or Sightengine?+
No fixed result is guaranteed. Detectors use private, changing models and can disagree on the same input. SynthGuard adjusts measurable characteristics and provides an image-signal comparison; verify the exact output in the workflow that matters to you.
Is it safe for my OnlyFans / Fansly account?+
No tool can guarantee account safety. Follow current identity, consent, rights and disclosure rules, and treat SynthGuard as a media-processing tool rather than a policy bypass.
Do my files get uploaded?+
Image and video content is processed locally. Text Light mode is local; Standard and Aggressive send text through the disclosed inference route. Authentication and quota metadata may also be recorded without including media file content.
What about Meta's 'Made with AI' label and Instagram shadowbans?+
Meta can use industry-standard provenance indicators and creator disclosure to add AI context. It does not publish a universal reach penalty tied to one asset, and editing a file neither guarantees label removal nor cancels disclosure duties.
Can I check if my content is undetectable before I post?+
Yes — our AI Image Detector is free, runs in your browser, and gives you an 8-signal verdict in under 5 seconds. Re-run it after humanizing to verify.
How fast is it?+
Photos: 3–6 seconds. Text: instant for Light mode, ~1–2 seconds streamed for Standard / Aggressive. Videos: depends on length and resolution but typically 1–3× real-time on modern hardware.
