Screen blur for live sharing and recordings

DataBlur is a browser extension that helps hide sensitive content on your screen in real time. According to the site, it works with one-click screen blur for live calls, screen sharing, and recordings, and it is designed to keep processing local rather than sending data to the cloud.

The product is aimed at people who need to present or record work that contains private details such as names, emails, phone numbers, API keys, and other on-screen values. The homepage also shows support for Chrome, Microsoft Edge, Brave, Comet, and Mozilla Firefox.

Core capabilities

Manual blur for elements, areas, and words

Users can click an element, drag a region, or select specific words to hide them exactly where they appear on screen.

Auto-blur by data category

The extension can automatically hide categories such as emails, phones, names, cards, API keys, and masked values across the page.

Blur lists with regex support

Users can enter comma-separated words or regular expressions so matching content is hidden wherever it appears on the page.

Per-site blur profiles

Blur settings can be saved as a profile and reloaded on the sites a user demos most often.

Similar-element detection

After blurring one cell in a pattern, DataBlur can suggest the rest of the matching elements so the same structure can be hidden more quickly.

Local-only processing

The site states that DataBlur works 100% locally with no cloud and no AI, which keeps the blur action on the device.
