Sentinel is a privacy-first browser extension that helps users stay aware of on-screen content by locally analyzing visible page text and applying user-controlled rules to warn, blur, or block content.
All processing happens entirely on your device. Sentinel does not collect personal data, does not track browsing activity, and does not send page content to external servers.
Privacy by design
Sentinel is built to be transparent and user-controlled.
