WatermarkCheck is a free online AI watermark remover and invisible character detector that removes hidden Unicode characters from AI-generated text and source code. If you need to remove ChatGPT watermarks, detect zero-width spaces, or clean hidden characters from text copied from Claude, Gemini, Copilot, Grok, DeepSeek, Perplexity, Mistral or Llama, WatermarkCheck finds and deletes every invisible mark without changing your visible words. The tool detects zero-width spaces (ZWSP), zero-width joiners, bidirectional controls, tag characters, non-breaking spaces, soft hyphens and other invisible Unicode symbols that AI chatbots and text editors can leave behind after copy-paste. A built-in x-ray view shows every hidden character before removal, so you always see exactly what gets cleaned. Students and writers use WatermarkCheck as an essay cleaner and text sanitizer for assignments, coursework, research papers, thesis and dissertation drafts, articles and reports. Developers use it as a code cleaner to find invisible characters that break identifiers, string comparison, JSON parsing, compilation and code formatting — errors that are impossible to spot by eye. WatermarkCheck is a privacy-first hidden character checker: everything runs in your browser, text is never uploaded or stored on a server, and no sign-up is required. Dedicated checker pages cover the specific invisible characters each AI model may insert. The service removes character-level hidden marks and formatting artifacts only. It does not remove statistical AI watermarks based on word choice and does not process images, audio or video — a clear, honest scope you can rely on when you need to check text for hidden characters and get a clean copy in seconds.Ver mais
