Redact & Snap is a Chrome extension that detects and redacts sensitive information (like emails, phone numbers, and API keys) on a webpage before taking a screenshot. It uses checksum validation for card numbers and IBANs to reduce false positives and allows manual redaction, all processed locally without network requests. This is useful for safely sharing screenshots without exposing private data.

Target audience: general users, developers, privacy-conscious individuals
