Hey! 👋 I’m Zikang, and I built PrivacyGuard because I realized how easy it is to accidentally share sensitive information with AIs like ChatGPT or Deepseek. Unless you’re using enterprise-level AI plans, your prompts can be used to train future models. Names, IDs, emails, documents — all part of a future dataset. PrivacyGuard is a Chrome extension that prevents that. It flags personal or identifiable info before you hit send. Whether you're pasting in resumes, tax docs, medical info, or just chatting casually, it helps you stay in control of what you share. We’re still in launch mode, but the waitlist is open! If you care about data privacy in the age of AI, I’d love your thoughts and feedback. Join the waitlist here! ➡️ privacyguard.cc
