What is PasteGuard?
Scanning text for API keys, bearer tokens, private keys, and personally identifiable information before sending messages to ChatGPT, Claude, Copilot, or similar chat tools happens entirely inside your browser with PasteGuard. The tool operates locally without uploading text or collecting analytics, working offline after the initial page load without requiring an account. You paste text into the box, review any flagged items, and redact data before moving it elsewhere.
