I almost leaked an API key into ChatGPT, so I built a Chrome extension

I use AI chats a lot when coding and analyzing logs. A few days ago I almost pasted a real API key into ChatGPT while sharing some logs. I noticed it just before sending. But it made me realize something: It's extremely easy to accidentally leak sensitive data when using AI chats. So I built a small Chrome extension called PasteSafe . What it does When you paste text into AI chats, it scans the content and detects things like: API keys emails phone numbers IBAN UUID URLs If something sensitive is detected, it automatically masks the values before sending . Example: API_KEY → [API_KEY#1] Works with ChatGPT Claude Gemini Privacy first Everything runs locally in the browser . no servers no tracking no data collection Try it https://pastsafe-ext.github.io/pastesafe/ GitHub repo: https://github.com/pastsafe-ext/pastesafe Curious: Have you ever accidentally pasted something sensitive into an AI chat?
