Stealth Browser Assistant

Stealth Browser Assistant helps you quickly manage private browser tabs when privacy matters. Set your own keywords or domains, and SBA automatically detects matching tabs by checking their URL or title. You decide exactly what should be considered private — whether that's a website domain such as bank.com, a keyword such as "paypal", or any other word you choose. Mute — Instantly mute all tabs matching your keywords. No need to find the right tab or use Chrome's native mute controls. Hide — Move matching tabs into a separate minimized "stash" window, keeping them out of sight. Restore them to their original position when you're ready. Emergency Mode — One keyboard shortcut can instantly mute and hide every matching tab. Designed for those "someone just walked in" moments. Match Feedback — Make matching tabs easier to spot with visual indicators, such as a replaced tab icon or a red border flash. Private Data Cleanup (Premium) — Clean private browsing data after you're done. SBA can remove matching browsing history, download history, and cookies/site data, scoped to the domains matching your keywords. An optional Auto Cleanup feature can run automatically after the last matching tab is closed. Keyboard Shortcuts — Quickly mute, hide, trigger Emergency Mode, or clean private data without opening the extension. Privacy by Design • Your keywords and extension settings are stored locally in your browser. • SBA does not track your browsing activity or collect page content. • No analytics or advertising. • SBA does not send your browsing history, URLs, page content, or other browsing data to our servers. • The only network requests are related to license activation and license status checks. These requests contain your license key and a device identifier hash, not your browsing activity. Free and Premium The free version provides the core tab management features. Premium unlocks additional features including unlimited keywords, emergency close-tabs mode, pause-on-mute, and private data cleanup. Built for Chromium browsers, including Chrome and Edge. Your browser. Your rules. Your privacy.
