When you copy text from ChatGPT, Claude, Gemini, or other AI assistants, invisible watermarks often ride along with the visible words. These hidden markers include zero-width Unicode characters (U+200B, U+200C, U+200D, U+FEFF), C2PA provenance metadata, and statistical token-sampling patterns embedded during generation.
Our AI watermark remover uses multi-layer detection to scan your content for all known watermark types, then strips them cleanly without altering the meaning of your text.
Works with text generated by ChatGPT (GPT-4, GPT-4o), Claude (Anthropic), Gemini (Google), Copilot, Llama, Mistral, and other large language models that embed watermarks or provenance marks in their output.
