I built a generic Privacy Shield for ChatGPT (and a Pro mode for Developers) 🛡️

The Copy-Paste Risk 😱

As developers, we are used to scrubbing our code before committing to GitHub. But what about when we paste into ChatGPT or Gemini?

One slip, and your client's email, phone number, or worse—your AWS keys—are in the chat history.

I built SafePaste AI to solve this. It acts as a local firewall between your clipboard and the AI input box.

The extension runs 100% locally. It hooks into the paste event and sanitizes text based on Regex patterns before it even touches the DOM.

I believe in sustainable software, so I adopted a Freemium model. Here is exactly what you get:

Great for general privacy and protecting PII (Personally Identifiable Information).

Why use this? To prevent accidental leaks of customer data during drafting emails or reports.

This enables the heavy-duty regex engines specifically for code and credentials.

API Keys & Tokens: Detects OpenAI (sk-...), AWS (AKIA...), Google (AIza...), Slack, and Discord tokens.
Security Secrets: Blocks Private Keys (-----BEGIN PRIVATE KEY...), JWTs (ey...), and DB Passwords.
Crypto & Finance: Masks Wallet addresses (ETH/BTC) and Credit Card numbers.
Customization: Add your own "Custom Words" or regex patterns to block specific internal project names.

Zero Analytics: I don't track what you paste.
Local Processing: All regex logic runs in your browser content.js. No data is sent to any server.

Whether you need the basic PII shield (Free) or the full Developer Security Suite (Pro), give it a spin.

Let me know if you have any feature requests! I'm actively working on adding more patterns.
