Secret Sanitizer – Paste Safely into AI Chats

Masks API keys, passwords and tokens before they reach AI chats. Runs locally. Nothing leaves your browser.

Code, logs and config files often hold secrets. Paste them into an AI chat and they end up on someone else's servers. Secret Sanitizer masks them the moment you paste, right in your browser, before anything is sent. 🛡️ HOW IT WORKS You paste: API_KEY=sk_live_51Hx9... The AI sees: API_KEY=[API_KEY_1] • Only the secret is replaced, so the AI still understands your code • Undo any masked paste within 5 seconds • Originals stay in memory for 15 minutes, never saved to disk 🔁 SMART RESTORE Copy the AI's reply and your real values come back in the clipboard, ready for your editor or terminal. The web page never sees them. 🔍 WHAT IT CATCHES 70+ patterns: API keys, access tokens, passwords, database URLs, JWTs, private keys, credit card numbers, and Indian IDs like Aadhaar and UPI. It also flags random strings that look like secrets. 🥷 PRIVATE BY DESIGN No account. No tracking. No network requests. Open source under MIT. Works on popular AI chat sites out of the box. Add any other site in one click. GOOD TO KNOW Only pasted text is checked, not typed text or file uploads. No detector is perfect, so review sensitive text before sending.
