Anthropic is embedding invisible identification codes into every text output generated by Claude. This code remains attached to the text even if you copy and paste it elsewhere.
Key points to know:
• Implemented starting August 2, 2026, on new-generation Claude models
• Invisible to human eyes, but detectable by scanning tools
• Applied globally, not just for users in Europe
• Complies with the EU AI Act on AI content transparency
• Some users are protesting, fearing getting caught when using it for work or school
[Insight: This label merely indicates “AI-generated text,” rather than accusing you of plagiarism. Cambodian students and freelancers should review and rewrite content in their own words before submitting their work.]
