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.
How it works (The Tech) 💻
The extension runs 100% locally. It hooks into the paste event and sanitizes text based on Regex patterns before it even touches the DOM.
Features Breakdown (Honest Pricing) 🏷️
I believe in sustainable software, so I adopted a Freemium model. Here is exactly what you get:
✅ Free Version (For Everyone / PMs / Sales)
Great for general privacy and protecting PII (Personally Identifiable Information).
-
Auto-Mask Emails: Converts
client@example.com→[HIDDEN-EMAIL] -
Auto-Mask Phone Numbers: Converts
+1-555-0199→[HIDDEN-PHONE]
Why use this? To prevent accidental leaks of customer data during drafting emails or reports.
⚡ Pro Version (For Developers & Engineers)
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.
🔒 Privacy First
- 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.
🤝 Multi-Platform Support
Works seamlessly on ChatGPT, Claude, Gemini, Microsoft Copilot, Deepseek, Poe, Mistral, Blackbox, Perplexity and Github Copilot.
Try it out 🚀
Whether you need the basic PII shield (Free) or the full Developer Security Suite (Pro), give it a spin.
