PageVeil is a Chrome, Edge, and Firefox extension that blurs, hides, or replaces sensitive data on live webpages before screen sharing, demos, recordings, and screenshots. Click an element, drag a region, or highlight exact words to cover them. Saved rules re-apply after refreshes and in-app navigation. Pro adds one-click Demo Mode, which detects 40+ types of sensitive data, plus realistic fake data and tab title masking. Detection and blurring run locally in your browser. Freemium: Free $0; Pro $12/month or $60/year.
