PasteGuard

PasteGuard is a client-side security tool that scans text for sensitive information, secrets, and personally identifiable data before you paste it into AI chatbots or other services. The entire scanning process happens locally in your browser with no data uploaded to external servers, ensuring complete privacy.

Key features include live scanning as you type, instant detection of secrets and PII, and the ability to generate redacted versions of your text for safe sharing. The tool works completely offline once the page is loaded, with no analytics tracking of your content.

PasteGuard is designed for developers, security-conscious users, and anyone who wants to prevent accidental exposure of sensitive data when interacting with AI assistants and other online platforms.
