Prompty

Extension Privacy & Security4 users

Overview

Detects sensitive data in browser-based AI prompts and warns users before submission.

Prompty scans your prompts for sensitive data before they reach any AI platform and blocks or redacts it automatically. Before you hit send, Prompty checks for credentials (API keys, passwords, access tokens), personal identifiers (email addresses, dates of birth, payment card numbers), and jurisdiction-specific data including NHS numbers, National Insurance numbers, Social Security numbers, Tax File Numbers, Medicare numbers, and more. Additional coverage is applied automatically based on your region. Prompty works across all major browser-based AI assistants.
