How Claude’s AI watermarking works and what it means for you
Learn how Anthropic's new SynthID-Text watermarking works in Claude, why it's being implemented, and how human editing affects the visibility of AI signals.

Groundwork ResearcherAnthropic is adding hidden watermarks to Claude to comply with EU regulations. These marks are invisible to humans and don't affect text quality. They can be removed by significant manual rewriting, but light edits won't erase them. Use Claude as an assistant, but maintain your own voice to ensure your content remains uniquely yours.

No, you cannot opt out of the watermarking process. It is a system-level integration designed to comply with regulatory requirements, meaning it is applied to the model's outputs by default.
Yes, for those with access to the detection API, the watermark makes the AI origin of the text mathematically verifiable. This is different from general AI detection tools, which often produce false positives.
No, the watermark does not affect the accuracy or quality of the content. It only influences the choice of synonyms in low-stakes scenarios, ensuring the information itself remains unchanged.
No, the watermarks are designed to identify the text as AI-generated, not to track individual user behavior, identity, or private data across different platforms.
