In the context of the rapid evolution of artificial intelligence technologies, the issue of content authenticity and copyright is coming to the forefront. Anthropic, the developer of one of the most powerful language models on the market — Claude, has announced the implementation of a new protection system. Starting August 2, 2026, all texts generated by the new generation of Claude models will be automatically marked with a special "invisible watermark." This solution is intended to address the growing distrust of digital content and assist in identifying materials created with the help of AI.
Marking Technology: How It Works
The new marking system is designed to be invisible to the human eye and not affect the readability or structure of the text. Unlike visible logos or links, this digital fingerprint is embedded directly into the data structure. It is important to note that the technology has been activated not only for users working directly on the Anthropic platform but also for all content generated through cloud providers. Developers have already begun integrating this system into older model versions, aiming to cover the entire spectrum of generated content.
Market and Literary Community Reaction
The implementation of watermarks occurs against the backdrop of serious conflicts in the publishing world. In July 2026, a well-known literary agency withdrew support for the novel "Call Me, I’ll Hide the Body" due to suspicions of AI usage. A similar situation occurred with the publisher Hachette, which pulled the horror novel "She Girl" from publication. In both cases, the authors categorically denied using neural networks; however, the lack of verification tools led to the cancellation of contracts. The technology from Anthropic is designed to resolve such disputes by providing objective evidence of the text's origin.
Tools for Third-Party Organizations
Anthropic plans to make the verification system available not just for internal needs. In the near future, the company intends to provide third-party organizations, publishers, and platforms with special tools to detect these watermarks. This will allow independent experts and editors to quickly determine whether a text was created with the help of AI, which is critical for complying with copyright legislation and publication ethics.
Context of Global Regulation
Anthropic's move is part of a broader trend in the technology sector. Previously, in 2024, Google DeepMind introduced the SynthID system for marking texts and videos created with the Gemini model. The implementation of such technologies is also driven by legislative initiatives, such as the Artificial Intelligence Act in the European Union, which requires transparency regarding the use of artificial intelligence. Anthropic has become the second major company to take responsibility for content marking, which could become a new industry standard.
