Anthropic embeds invisible watermarks in Claude text for EU compliance

Anthropic has begun embedding invisible watermarks into text generated by its Claude AI model, a change prompted by the EU Code of Practice on Transparency of AI-Generated Content. This technique, based on Google DeepMind's SynthID-Text, subtly alters word choices that appear random to readers but can be detected with a key. While the watermark is designed to survive minor edits like grammar checks, it can be removed by substantial rewrites. Anthropic plans to release a detection API, which will allow for the verification of content originating from Claude. AI

IMPACT This move by Anthropic sets a precedent for AI-generated content identification, potentially impacting how AI-assisted writing is perceived and regulated globally.

    The grammar check that outs you as a machine

    <p>Anthropic started embedding invisible watermarks into every piece of text Claude generates. If you've used Claude for a draft, an email, or a chunk of your book this week, that text now carries a signal you can't see, designed to survive copy and paste. This is not a hypotheti…
