How the AI watermark remover works
- 1. Paste your text. Drop in any answer from Claude, ChatGPT, Gemini or another AI assistant.
- 2. Review the scan. Every hidden character is listed by Unicode code point, name and position so you can see exactly what was embedded in the text.
- 3. Clean and copy. Remove the invisible markers, then copy or download clean text that reads identically to the original.
