ContextBlur – Blur any webpage element instantly before screen sharing

Summary: ContextBlur lets users blur specific elements on any webpage with one click, preserving privacy during screen sharing. Blurs persist through page refreshes and restarts, and auto-detection hides sensitive data like emails and credit cards. It operates fully locally without sending data off-browser.

What it does

ContextBlur enables instant blurring of webpage elements that remain blurred after refreshes and browser restarts. It auto-detects and blurs emails, phone numbers, credit cards, and SSNs, and works across all websites using a keyboard shortcut or direct clicks.

Who it's for

It is designed for anyone sharing their screen who needs to protect sensitive information visible on web pages, such as client data, personal details, or confidential dashboards.

Why it matters

ContextBlur solves the risk of unintentionally exposing private or sensitive data during screen sharing by providing persistent, local blurring without requiring accounts or sending data externally.
