About this extension
DemoGuards keeps sensitive information off the screen while you share, demo, or record.
The moment a page loads, DemoGuards scans the visible text for things that shouldn't be in a screenshot — customer emails, phone numbers, credit cards, SSNs, JWTs, API keys and tokens from popular developer and SaaS tools, and social handles — and quietly blurs them. Hover to read, click to confirm, share with confidence.
WHY TEAMS USE IT
• Sales engineers running live demos on real production data
• Support agents screen-sharing customer accounts
• Founders pitching with their actual dashboard open
• Developers recording loom walkthroughs of internal tools
• Anyone who has ever pasted an API key into the wrong window
FOUR PANIC TRIGGERS
When something slips through, hide everything in one motion:
• Double-tap the right Shift key
• Click the floating shield button in the corner of any tab
• Press the toolbar icon → "Panic blur"
• Keyboard shortcut Ctrl+Shift+H (Cmd+Shift+H on Mac)
CUSTOM REDACTION RULES
Define your own patterns in the dashboard — internal codenames, customer IDs, account numbers — and DemoGuards will redact or substitute them automatically wherever they appear.
PER-SITE CONTROL
Pause DemoGuards on sites you trust from the toolbar popup. Settings sync to your team account.
PRIVACY-FIRST BY DESIGN
• Page content is scanned locally in your browser. Nothing is sent to our servers.
• Only event counts and SHA-256 hashed domain names are reported back, and only when you enable the audit log.
• You can disable all reporting from the dashboard.
PRICING
14-day free trial on every plan. Solo $5/mo, Pro $19/mo, Team $49/mo. Manage your subscription at demoguards.com.
