About Secret Sanitizer

Secret Sanitizer is a Chrome extension that catches your secrets before AI does. Paste code, logs, or configs into any AI chat and it automatically finds API keys, passwords, tokens, and 50+ other secret patterns, then masks them before anything leaves your browser. Your real values stay locked in an encrypted vault on your machine. When the AI responds, just copy it and Smart Restore automatically swaps the placeholders back so you can use it straight in your code. No servers. No network calls. No tracking. Fully offline, fully open source. If you've ever pasted a .env into an AI chat and felt that "wait, did I just…" moment, you never have to worry about that again.
