<h1>Private AI Generated Text Detection</h1>
<!-- 1 — Why it matters -->
<p class="explanation-text">
AI models can embed an invisible <strong>watermark</strong> – a tiny cryptographic
signature hidden in the text – that proves the text came from them.
This demo shows you can <em>detect</em> such a watermark
while your words stay fully encrypted in your browser, thanks to
<a href="https://www.zama.ai/" target="_blank">Fully Homomorphic Encryption (FHE)</a>.
</p>
<!-- 2 — How it works in plain English -->
<p class="explanation-text">
• Your text is encrypted locally.<br>
• Our server runs a watermark detector on the ciphertext.<br>
• Because of FHE, the server never sees the plaintext. Neither does it learn whether you text is
"watermarked" or "not watermarked."
</p>
<!-- 3 — Scope of the demo -->
<p class="explanation-text">
In this prototype we look for the
<a href="https://deepmind.google/science/synthid/" target="_blank">Google SynthID</a> watermark
as a real-world example.
<strong>No watermark</strong> simply means "no SynthID detected" — the text
might still be human-written or AI-generated without that specific mark.
</p>
</div>
<div class="hero-diagram">
<img src="visual.png" alt="Workflow diagram showing 6 steps: 1) Generate keys in browser, 2) Encrypt text provided locally, 3) Send encrypted text to server, 4) Server performs watermark detection on encrypted data, 5) Return encrypted result to browser, 6) Decrypt result locally. The diagram shows the user/browser on the left and server on the right with arrows indicating data flow.">

<p><strong>Note about reliability:</strong> AI text detection works best with longer passages (100+ tokens). In this demo, input is limited to 16 tokens for performance, which may affect accuracy. Reliability improves significantly with 10+ tokens but is less reliable on very short snippets.</p>
