AI watermarking is here: every word Claude generates now carries an invisible signature. Here's what it means for marketers using AI in their workflows, and what to do about it.
Anthropic activated a watermarking system across all Claude models released from August. The trigger? Article 50 of the EU AI Act, which requires AI providers to make machine-generated content identifiable.
The watermark is invisible to the reader. It works by subtly influencing the model's word choices, a technique called SynthID-Text, developed by Google DeepMind. For files, Claude uses the C2PA standard with digitally signed provenance metadata.
What changes for marketing teams using AI?
Transparency becomes the default, not the exception.

Your workflow needs a conscious layer of human review.
This is exactly why we say Human + AI: AI is a powerful tool, but strategic thinking, editing, and accountability stay human.
