Alexander Serban Maker Pinned on this launch

I built this after seeing how easy it is to paste config snippets or logs into AI chat with keys, tokens, auth headers, or personal data still inside. The first version is intentionally local, conservative, and clear about its limits.

About Prompt Leak Guard

Prompt Leak Guard runs locally in the browser to scan prompts, logs, and config snippets for common secrets and personal data before they are pasted into AI tools. It flags risky patterns and creates a sanitized copy without sending content to a server.
