Inspect hidden text artifacts locally in your browser.
ClaudeWatermarks is a free browser-based inspector for directly observable Unicode and clipboard formatting artifacts in pasted text. It shows each finding with its position, category, context, and proposed change so users can review changes before cleaning. Text is processed locally and is not uploaded or stored. A separate C2PA checker inspects supported file credentials locally. ClaudeWatermarks does not claim to detect undisclosed model-level watermarks or prove authorship, and it is not affiliated with Anthropic.
