About
When you paste into supported AI sites (such as Gemini, ChatGPT, Perplexity, or Claude), PromptGuard scans the content locally on your device for patterns which may indicate sensitive data— such as paswords, API keys, private keys, tokens, or personally identifiable information. If a potential risk is detected, PromptGuard displays a clear warning so you can review the content before continuing. Key features include: ⚠️ Real-time warnings before you send risky content 🧠 Explainable results showing why content was flagged 📊 Local analytics dashboard with aggregated counts only 🔒 Privacy-first design — no prompt content is stored or transmitted Privacy & Security: All analysis is run entirely in your browser. No text you type is sent or stored anywhere, and analytics are anonymous and local to your device. There are no accounts, tracking, or external servers.
