Preview any website across mobile, tablet, laptop, and desktop sizes side by side, in one click. Sense — Preview any website on four screen sizes at once Sense is a browser extension that shows how any website looks on Mobile, Tablet, Laptop, and Desktop — side by side in one tab. No more resizing your browser window or fighting with developer tools. Click the Sense toolbar icon (or press Ctrl+Shift+Y) on any website. A grid opens with four device cards. Each card shows the page at a real device width, so you see the layout change just like a real visitor would. You can: - Change the device for each card — iPhone SE, Pixel 7, iPad Pro, MacBook Air, and more - Switch a card between portrait and landscape - Take a screenshot of one card, or all four combined into one image Key features - Preview four device types at once: Mobile, Tablet, Laptop, and Desktop. Each has a dropdown of real device sizes. - Portrait/landscape switch on every card, with a clear label showing which mode you’re in. - One-click screenshots: save a single device or combine all four into one image. - Show or hide device types — for example, view only Mobile and Tablet. - Light and dark mode. It follows your system by default, or you can set it manually. - Remembers your last URL, device choices, visible categories, and theme. - Recent URLs menu for quickly previewing sites you’ve checked before. - Custom device list you can edit on the Options page. - Short guided tour for new users. You can reopen it anytime from the toolbar. Privacy Sense only works with the preview frames inside its own tab. It doesn’t collect analytics, track your browsing, or send your data anywhere. Everything it remembers is stored locally in your browser.
