Chrome extension
Overlay design mocks directly on live webpages
The UI Overlay Chrome extension is published on the Chrome Web Store and adds a compact page control panel for visual comparison, annotations, and report export inside the browser.
Auto-inject controls
Enable a floating page button so the overlay controls are ready when normal webpages finish loading.
Page-scoped state
Keep selected mocks and transform values tied to the page path you are reviewing.
Annotations
Switch annotation mode on to draw issue boxes, then export a review report for handoff.
Privacy-friendly by design
The extension does not upload mock images, webpage content, annotations, or browsing data to a remote server. It stores settings and overlay state locally.
