react-redact is a zero-dependency React “demo-safe mode” you can toggle with a single keyboard shortcut.

Wrap your app in <RedactProvider> and hit Cmd+Shift+X (or Ctrl+Shift+X) to instantly blur, mask, or replace marked (or auto-detected) PII like emails, phone numbers, SSNs, credit cards, and IPs.

It’s a visual-only helper for demos and screenshares (it does not remove data from the DOM), and it’s Next.js and TypeScript friendly.
