Protect sensitive text before it leaves your browser.

PrivacyGuard is designed for developers, security-conscious teams, and AI users who paste code, support tickets, customer notes, or internal data into chatbots.

Local detection

PII and secret detection runs in the browser using local rules. Your scanned text is not sent to PrivacyGuard servers.

Pre-send warning

Warnings appear before you submit text, so you can redact, cancel, or intentionally continue.

One-click redaction

Replace detected secrets with placeholders and keep your workflow moving without manual editing.

Configurable rules

Choose which detection categories are active, including API keys, passwords, private keys, JWTs, emails, phone numbers, and IDs.

Simple permissions

The extension uses browser storage for settings and site access to detect sensitive text in supported input fields.

No account required

Install the extension and start scanning. Pro unlocks unlimited scans through a license tied to your purchase.

Works with major AI chat platforms.

Use PrivacyGuard with the AI tools where sensitive paste mistakes are most likely to happen.
