Anthropic announced on August 11, 2026 that it would begin watermarking text generated by Claude, embedding statistical word-choice patterns invisible to human readers but detectable by dedicated tools. The method reportedly works by favoring certain equally valid word substitutions — a subtle pattern rather than any visible marker like emojis or odd characters.
The announcement triggered a rush of demand for watermark-removal apps, according to the report, and with it a wave of fraudulent tools making false claims or bundling malware. The piece notes such watermarks can already be defeated through editing, embedding in larger texts, or reprocessing through other AI systems, and warns the scam problem will worsen as more AI providers adopt similar watermarking.
