AI Text Watermark Remover for Claude

Claude models released on or after August 2, 2026 embed an invisible statistical watermark in generated text, and Anthropic is extending it to older models. These hidden patterns can flag your content as AI-written. This tool works on both layers: Quick Clean strips 34+ invisible Unicode characters — 100% in your browser, nothing uploaded; Deep Rewrite uses LLM rewriting to break statistical patterns (best-effort). Free, no account needed.
