Screen sharing privacy
Blur sensitive data
before you share.

Click any sensitive field to blur it
One wrong click. Whole room sees it.
A Slack DM pops up. An HR tab is open. A client's account number is visible.
That Slack DM you didn’t close
Mid-presentation, your screen shows a private message from your manager about someone’s performance review.
Your salary on that HR dashboard
You’re sharing your screen to show a workflow, and there’s your compensation info in the sidebar.
Client data you can’t legally share
You’re demoing to a prospect, but the screen has real customer names, emails, and account numbers visible.
How it works
30 seconds. That's it.
Install. Click. Blur. Already sharing privately.
Click the icon
Activate blur mode from the toolbar or press Ctrl+Shift+B. Takes one second.
Click to blur
Hover over any element — text, images, notifications, fields. Click to blur it instantly.
Share with confidence
Blurred elements stay hidden, even after refresh. Present, demo, and stream worry-free.
Features
Everything you need. Nothing you don't.
Purpose-built to do one thing and do it right.
One-click blur
Hover and click any element to blur it. Text, images, notifications, form fields — anything on the page.
Auto-blur sensitive data
Detects and blurs emails, phone numbers, SSNs, and credit card numbers automatically.
Persistent blurs
Blurred elements stay hidden across page refreshes and browser restarts.
No extension telemetry
The extension does not track the pages you visit or send page content to a server. Blur processing stays local.
Use cases
Built for how you actually work
Start with the workflow where one visible tab, customer name, or secret can do the most damage. That is usually the fastest path from install to real value.
Keep meetings professional
You’re on a Zoom call sharing your screen. Slack notifications, email previews, and personal bookmarks are all visible. Blur them before you share — they stay blurred for the whole meeting.
