SEOULTRA Plugins
PasteFilterNew
A privacy-first browser extension that watches what you paste into web pages — chat boxes, forms, tickets, dashboards — and catches API keys, passwords and personal data before they land. Block it, mask it, or swap in realistic-but-useless fake data. Everything runs on your device.
Chrome & Firefox stores coming soon
The Randomize mode
Instead of an obvious [REDACTED], a credit card becomes another Luhn-valid but fictional card, an email becomes [email protected], an IP becomes 203.0.113.x. The AI or form still gets well-formed input — just not your real data.
Four ways to react
Off
Stays out of the way.
Warn
A dialog shows what was found and lets you choose.
Mask
Replaces each secret with a [[PLACEHOLDER]].
Randomize
Swaps each secret for realistic fake data.
What it detects
Every structured match is validated locally, so ordinary text like order numbers or version strings is left alone.
Secrets
Private keys, JWTs, Bearer tokens, AWS / GitHub / Google / Slack / SendGrid / Stripe keys, database connection strings and .env credentials.
Personal data
Emails, phone numbers, credit cards (Luhn), IBANs (mod-97), IPv4/IPv6 addresses and EU VAT numbers.
Private by design
No network requests. No analytics, telemetry, cookies or fingerprinting. No sign-in. Settings and a local counter stay on your device only.
