Your Chatbot Uses Claude API. Claude Adds Watermarks. We Strip Them.
Real-time watermark removal for chatbot responses. Add one middleware layer → protect all users. Streaming support included.
const response = await fetch(
"https://api.gptwatermarkremover.com/v1/clean",
{
method: "POST",
headers: {
"X-API-Key": "YOUR_API_KEY",
"Content-Type": "application/json"
},
body: JSON.stringify({ text: "Your AI-generated text here" })
}
);
const { cleaned_text } = await response.json();The Chatbot Watermark Problem
You use AI APIs for chatbot responses. AI providers embed watermarks. User's company runs AI check. Busted.
1. User Asks Question
Your chatbot receives query from sales rep, support agent, or employee.
2. Claude API Responds with Watermarks
You call claude.messages.create(). Response contains invisible tracking characters.
3. User Copies → Gets Detected
User pastes response into email/Slack. Company AI detector flags it. Trust lost.
The Fix: Middleware Watermark Removal
Add watermark removal between Claude API response and user display. User sees clean response in <2.1 seconds total (2 sec AI + 0.1 sec cleaning).
// Your chatbot streams response from Claude
const stream = await anthropic.messages.stream({
model: "claude-3-5-sonnet-20241022",
messages: [{ role: "user", content: "Help me..." }],
max_tokens: 1024
});
let fullResponse = "";
for await (const chunk of stream) {
if (chunk.type === 'content_block_delta') {
fullResponse += chunk.delta.text;
}
}
// Strip watermarks from complete response
const clean = await fetch(
'https://api.gpt-watermark-remover.com/v1/remove',
{
method: 'POST',
headers: { 'X-API-Key': 'your_api_key' },
body: JSON.stringify({ text: fullResponse })
}
);
const { clean_text } = await clean.json();
return clean_text; // ✅ No watermarksMiddleware Pattern

Watermark Types We Detect
Our API detects and removes all known invisible Unicode characters used by AI systems like ChatGPT, Claude, Gemini, and others to watermark generated text.
Zero-Width Characters
Invisible characters with no visual width, commonly inserted by AI systems to mark generated text.
Formatting Characters
Characters that affect text rendering or spacing without being visible.
Bidirectional Control
Characters that control text direction, often invisible and exploitable for watermarking.
Variation Selectors
Characters that modify how preceding characters render, often invisibly.
Annotation Characters
Characters for interlinear annotations, invisible in most contexts.
Why Do AI Systems Add Watermarks?
Large language models like ChatGPT, Claude, and Gemini embed invisible watermarks to enable detection of AI-generated content. These watermarks use Unicode characters that have zero visual width but can be detected programmatically. Our API removes all known watermark patterns while preserving your text's meaning and formatting.
