Built for creatorswho ship every day.
SynthGuard.net builds privacy-first tools for images, video and text. Media humanization and image detection run locally; Light-mode text stays in the browser, while Standard and Aggressive text use a disclosed inference route. We document those boundaries so users can choose the right mode for their work.
Privacy by architecture
Image and video files stay on your device. Text mode boundaries are disclosed before processing.
Built for production
Sub-5-second processing, batch flows, predictable weekly credits. No per-call billing surprises.
Honest detection
The free detector reports eight local forensic signals with limitations, not a guaranteed platform verdict.
Responsibility
Tim Geithner
Founder and technical reviewer for SynthGuard.net. Product architecture, privacy disclosures and research-oriented content are reviewed against the current implementation; dated tests state their method and limits.
Why we built this.
Detection is getting stricter every month. Creators and OFM operators were stuck choosing between server-side tools that hold their content hostage and rough open-source scripts that don't fool modern classifiers.
SynthGuard is the version of the tool we wanted to use ourselves: technical, fast, transparent about its pipeline, and architecturally incapable of leaking your work.
Working withteams we trust.
A small circle of independent builders we partner with — sharing engineering notes, cross-testing detection signals, and trading honest feedback on what actually ships.
PhotoRadar
Geolocation intelligence that pinpoints where a photo was taken from a single image — visual forensics that complements our humanization stack from the opposite direction.
Velora AI
Realistic AI influencer models with consistent identity across photos and videos — built for creators who need believable, repeatable characters across production workflows.
