  • Database Writes

    There is no backend database to write to.

payload_inspector.json
// This is the ONLY data that leaves your device (Analytics)

{
  "n": "chat_started",        // Event Name
  "u": "https://.../chat",    // Current URL
  "d": "thischatneverexisted.com", // Domain

Common Verification Questions

How can I verify that Gemini Nano is running locally?

You can verify local execution by disconnecting your internet connection after loading the page. The chat will continue to function perfectly because the AI model (Gemini Nano) is downloaded to your device and runs offline.

Does the Chrome Prompt API send data to Google?

No. The Chrome Prompt API is designed to run local models. When using Gemini Nano via this API, all processing happens on your device's CPU/GPU. No data is sent to Google's cloud for inference.

Why do I see network requests to plausible.io?

We use Plausible Analytics for privacy-friendly, anonymous usage tracking. These requests only contain event names (like "chat_started") and never include your message content or personal data.

Is it safe to use local AI for private documents?

Yes. Since the AI runs in your browser's isolated environment and has no network access for chat data, it is safe to paste private text. The data physically cannot leave your machine.
