OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…

I kept pasting code with hardcoded API keys, database credentials, and auth tokens into ChatGPT while debugging. Copy a failing function, paste it into AI, and realise your AWS secret key or Stripe token was right there in the snippet. So I built (with some help from Claude) a simple Chrome extension that intercepts the paste, detects secrets using local regex, and replaces them with [MASKED] before they reach the chat. Originals stay in a local AES-256 encrypted vault for unmasking. No servers. No network requests. No tracking. ~41 KB, zero dependencies. Don't take my word for it: 'grep -r…
