ZenithGuard

Blocks ads, trackers and malware sites with Chrome's own blocking engine. Private, no account. Optional Gemini AI tools.

ZenithGuard blocks ads, trackers and dangerous sites, and gives you simple tools to clean up the pages you visit. It runs on Chrome's built-in blocking engine, so it's fast, and your browsing never goes through anyone's server. WHAT IT DOES • Blocks ads and trackers using EasyList and EasyPrivacy, plus a built-in list of major ad networks • Hides leftover ad boxes, and optionally cookie banners • Stops pop-up and pop-under ads • Blocks known malware and phishing sites (public URLhaus and phishing lists, updated daily) • Removes YouTube ads • Quiets "please allow ads" popups from Google's ad-blocking recovery YOU'RE IN CONTROL • Pause on one site, or everywhere for 15 minutes or an hour • Mark a site as broken and ZenithGuard steps back there • Zapper and Inspector: click any element to hide it for good • My Rules: your own blocks, hidden elements and site settings, with backup and restore • Focus Mode: block distracting sites for 25 or 50 minutes SEE WHAT'S HAPPENING • Popup with a privacy grade and blocked counts for the current site • Network Logger: every request a page makes, and which rule blocked it • Site Analyzer and Extension Health OPTIONAL AI (YOUR OWN GEMINI KEY) Add a Google Gemini API key to get AI page analysis, "hide this with AI", help with anti-adblock walls and cookie banners, and network summaries. AI features only run when you use them and send only what that action needs, directly to Google. Without a key, ZenithGuard works fully offline from its built-in lists. PRIVACY No account, no analytics, no tracking, no remote code. Settings stay in your browser. The only network traffic ZenithGuard makes on its own is a daily download of public malware and phishing domain lists, and you can turn that off. Full policy: see the privacy policy link on this page. Filter lists: EasyList and EasyPrivacy (CC BY-SA 3.0), malware-filter URLhaus and phishing lists (CC0 / CC BY-SA 4.0). Credits are in NOTICES.txt inside the extension. Some sites may act differently when ads are blocked. If a site breaks, pause ZenithGuard there with one click.
