Secret Sanitizer – Paste Safely into AI Chats

Description

Masks API keys, passwords and tokens before they reach AI chats. Runs locally. Nothing leaves your browser. Stop leaking API keys and passwords into AI chats. 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. Works on popular AI chat sites out of the box. Add any other site in one click. HOW IT WORKS: You paste: API_KEY=a8Fk2mQ9vLtR4wZ7nB1cYp3H The AI sees: API_KEY=[API_KEY_FORMAT_x7m2_0] - 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 and are never saved to disk. SMART RESTORE: Copy the AI's reply and the real values come back in your clipboard, ready for your editor or terminal. The web page never sees them. WHAT IT CATCHES: 70+ patterns, including 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, even without a known format. PRIVATE BY DESIGN: Runs fully offline. No account, no tracking, no network requests. Open source under MIT, so anyone can read the code. GOOD TO KNOW: Only pasted text is checked, not typed text or uploaded files. No detector is perfect, so review sensitive text before you send it.
