Hey Product Hunt! I'm Emil, and I built ContextBlur because I was tired of the pre-meeting panic. The problem: Every screen share is a gamble. You close your tabs, hide your bookmarks, enable DND — but the CRM sidebar still shows other client names. The HR dashboard still has salary columns. The Slack notification still sneaks through. It happened to me during a client call, and I decided to fix it permanently. What ContextBlur does: Click any element on any webpage to blur it instantly Blurs persist across page refreshes and browser restarts Auto-blur scans for emails, phone numbers, credit cards, and SSNs Keyboard shortcut (Ctrl+Shift+B) to toggle blur mode Works on every website — Gmail, Slack, Notion, Salesforce, Jira, everything What makes it different: 100% local. No data ever leaves your browser. No server. No analytics. No account required. Persistent. Other tools lose your blurs on refresh. ContextBlur remembers them. Minimal permissions. Only needs storage and sidePanel. No tabs permission, no remote code. Pricing: Free forever (5 blurs/session). Pro is $19 lifetime or $3/month for unlimited blurs + auto-detection. I've also written a full library of screen sharing privacy guides at contextblur.app/blog covering Zoom, Teams, Meet, Slack, Webex, HIPAA, GDPR, and more. Would love your feedback — what sensitive data do you worry about most during screen shares? What features would make this more useful for your workflow?
