About this extension
Sentry AI is a free, open-source browser privacy shield engineered for the modern AI web.
Core Defense Pillars:
1. Commercial Anti-AI Training Defense: Blocks AI crawlers (Meta, OpenAI, Google) from harvesting your browsing history; injects Sec-GPC: 1 and X-Robots: noai headers.
2. Mathematical Hardware Cloaking: Injects deterministic Mulberry32 PRNG noise across Canvas 2D, WebGL, and AudioContext to defeat fingerprinting without breaking CAPTCHAs.
3. Lightning Declarative Filtering: Over 120,000+ pre-compiled rules drop ads and trackers at the network layer with 0ms latency.
4. Universal Cookie Auto-Reject: Automatically declines consent dialogs and unlocks frozen page scrolling.
5. Clean Links & URL Sanitizer: Strips 50+ tracking tokens (utm_*, fbclid, gclid) dynamically on every click.
6. Point-and-Click Element Zapper: Permanently removes annoying page clutter and restores disabled right-click context menus.
