We’re introducing SynthID Bio, bringing our watermarking technology to synthetic biology.

Today, we’re introducing SynthID Bio, a new technology that watermarks AI-designed proteins while preserving their biological function.

SynthID Bio embeds an imperceptible, verifiable watermark directly into biological designs, such as AI-generated protein sequences and predicted 3D structures.

In laboratory tests across target proteins, our watermarked designs successfully matched the performance and natural diversity of unwatermarked versions. This creates a vital provenance layer to strengthen biosecurity and preserve the integrity of open scientific databases.
