Auto Blur

About

Stop leaking secrets on screen shares.

Auto Blur is a Chrome extension that finds sensitive data on any webpage - passwords, API keys, credit card numbers, emails, tokens - and hides them in real time, before anyone else can see. Runs 100% on your computer. No account, no servers, no tracking.

WHAT IT HIDES
  • Email addresses
  • Phone numbers
  • API keys (Stripe, bearer tokens, generic)
  • JWTs
  • AWS access keys
  • Credit card numbers (Visa, MC, Amex, Discover)
  • Private keys (PEM blocks)
  • GitHub tokens (classic + fine-grained)
  • Inline passwords and secrets (password: …, client_secret: …)

  HOW IT WORKS
  • Install, and it starts working immediately on every site you visit.
  • Sensitive values are hidden behind a soft blur. Click any one to peek for 3 seconds, then it re-hides itself.
  • Adjust the blur intensity from the popup. Toggle per-site if needed.

  PANIC MODE (Pro)
  Someone walks up mid-screenshare? Hit Option+Shift+B (or Alt+Shift+B on Windows) and the entire page blurs instantly. Hit it again to restore.

  CUSTOM RULES (Pro)
  Add your own regex patterns — employee IDs, internal URLs, project codenames, anything else you don't want flashing on screen.

  PER-SITE CONTROLS (Pro)
  Pause or disable Auto Blur on specific domains when you actually need to see the values. Works across all subdomains and iframes.

  PRIVACY BY DESIGN
  • No account. Install and use.
  • No servers for the extension. Nothing to phone home to.
  • No tracking. Not even usage metrics.
  • Allowlist is stored as an irreversible fingerprint — not even we could recover what you added.

  Free forever for the core pattern-detection features. Pro features available via a token (details at the link below). Suitable for developers, designers, support agents, or anyone who screen-shares code, email, or dashboards.
