Anthropic has launched an invisible, machine-readable watermarking system for text generated by its Claude AI models [1]. The technology embeds data directly into text patterns without affecting readability [1][3]. This feature allows platforms to detect AI-generated content and helps the company meet transparency standards [2].
The update primarily aims to satisfy legal requirements set by the European Union’s AI Act [1]. These regulations demand that AI providers clearly identify synthetic content to prevent deception [2]. Anthropic’s approach ensures that the watermark remains detectable even if the text is moved across different platforms [1][3].
