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.
Zero data collection
No analytics, no tracking, no server calls. Everything runs locally in your browser.
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.

Popular Guides
Start with the pages already matching real search intent
These are the platform and workflow guides most aligned with how people actually search for screen sharing privacy help.
Most Valuable Paths
The two content tiers that should drive installs and upgrades
Tier 1 pages win direct product demand. Tier 2 pages widen the funnel, clarify the problem, and push readers toward downloads, features, and pricing.
Tier 1: close-to-install guides
These are the pages to push hardest because the user already knows the problem and wants a concrete fix.
Tier 1
Blur sensitive data during screen sharing
The broadest install-intent workflow. Best entry point for Meet, Zoom, Teams, and browser-based demos.
Tier 1
Hide sensitive info in Google Meet
Strongest platform-specific guide for people already mid-problem and close to action.
Tier 1
Hide Slack messages and DMs
High click-intent privacy problem tied to a recurring workflow people will pay to solve reliably.
Tier 1
Compare screen-sharing privacy extensions
Commercial comparison traffic with the clearest path from evaluation to install and upgrade.
Tier 2: expansion and clarification guides
These pages broaden reach, win more variants, and hand off readers to the guides and product pages that monetize better.
Tier 2
Share without showing other tabs
Captures high-volume browser workflow confusion and feeds users toward install-ready how-to pages.
Tier 2
Share dashboards without exposing customer data
Lower-volume than generic privacy terms, but much higher commercial value for demos, RevOps, and consulting teams.
Tier 2
Screen blur vs background blur
Good top-of-funnel clarifier that fixes confusion before users choose the wrong product category.
Tier 2
Avoid oversharing when screen sharing
Broader awareness query that expands your citation footprint and routes users into more commercial guides.
Install it on one real page before your next call.
If it saves one risky demo, support call, or recruiting screen, keep it. If the workflow repeats every week, unlock Pro later.
