Extension Metadata

About this extension
OBSERVE-PII detects contextual Personally Identifiable Information (PII) in real time as users interact with text fields and web content. It helps users become more aware of potential sensitive data exposure by identifying categories such as names, emails, phone numbers, addresses, IDs, financial information, and more.

The extension uses a locally bundled ONNX-based AI model for inference. All processing is performed entirely on-device, ensuring that no user data is stored, transmitted, or shared externally. The tokenizer and model are loaded within the extension, and inference runs through ONNX Runtime (WASM).

Key features:
- Real-time PII detection on highlighted text
- Multi-category classification of sensitive information
- Fully local processing (no network calls)
- No data collection or storage
- Lightweight ONNX TinyBERT-based model

This extension is designed to promote safer browsing behavior and increase user awareness of sensitive data exposure.

Note: This is an initial release of OBSERVE-PII intended for testing and evaluation.
