The best way to detect your content is to watermark it.

Our imperceptible watermarking technologies embed an unfalsifiable signal into every piece of AI-generated content, allowing you to prove its origin, authenticity, and traceability throughout its entire lifecycle.

Watermarking: the science of built-in traceability.

Watermarking enables native traceability of content.
It relies on the controlled injection of micro-signals at generation time, in the form of subtle modulations of the content’s statistical, spatial, or frequency components.
These variations create an origin signature, unique, unfalsifiable, and inseparable from its source.

Born from French and European public research, our watermark carries the legacy of fifteen years of scientific excellence.
Its reliability and robustness now set the standard for digital traceability technologies.

Watermarking, a modular
by design technology.
