Hushh

A Chrome extension that hides sensitive information during screen recordings and screenshots. Point at any element containing a secret, click once, and that value stays blurred wherever it appears on the page.

How it works

When you protect a piece of text, Hushh stores it in memory and scans the entire page for that exact string. Every element containing it gets blurred inline using CSS filter: blur(), which renders into the OS compositor so Loom, Zoom, QuickTime, OBS, and every other recorder see the blur.

When the page navigates or the value appears in a new element, Hushh re-scans automatically. Nothing is ever sent to a server.

Features

• Click any element or highlight any text to protect it
• Blur follows the value across the whole page, including after navigation
• Works with inputs, textareas, and any text node
• Drag to select a region and protect everything inside it
• Keyboard shortcuts: ⌥⇧H / Alt+Shift+H to activate, ⌥⇧X / Alt+Shift+X to clear all
• Zero network requests, zero storage
