AegisPrompt Scanner — See What You're Sharing with AI

Silently counts sensitive data sent to ChatGPT, Claude, Copilot, Gemini, and Perplexity. No blocking. Just visibility.

AegisPrompt Scanner — See What You're Sharing with AI You use ChatGPT, Claude, Copilot, Gemini, and Perplexity every day. AegisPrompt Scanner quietly counts the sensitive data you've sent to them — and shows you the report when you're ready to look. AegisPrompt Scanner is a free, lightweight Chrome extension that runs entirely on your device. Unlike traditional security tools, it doesn't block, warn, or interrupt anything. It just watches what you submit, scans for sensitive data patterns, and keeps a running count on the extension icon. Click the icon whenever you're curious to see your report. Most people are surprised by what they find. That's the point. WHY THIS EXISTS 89% of professionals use AI tools at work. 1 in 4 have accidentally shared sensitive information. Most of those people would tell you, with confidence, that they're "careful about what they send to ChatGPT." The Scanner exists because confidence and reality are different things, and you can only see the gap if something is actually counting. This extension is intentionally passive. There's no prevention, no blocking, no enforcement — just visibility. We built it that way because awareness has to come before action. You can't fix a problem you don't see. WHAT IT DETECTS Personal Information: - Email addresses - Phone numbers (with smart validation to reduce false positives) - Social Security Numbers - Physical addresses Financial Data: - Credit card numbers (Luhn algorithm validated) - Bank account numbers - Routing numbers API Keys & Tokens: - AWS Access Keys and Secret Keys - GitHub Personal Access Tokens - Google API Keys - Slack Tokens - Stripe API Keys Cryptocurrency: - Bitcoin addresses (legacy and SegWit) - Ethereum addresses All detection happens locally in your browser using pattern matching. The Scanner never reads AI responses, only what you submit. SUPPORTED AI PLATFORMS - ChatGPT (chat.openai.com, chatgpt.com) - Claude (claude.ai) - Microsoft Copilot (copilot.microsoft.com, m365.cloud.microsoft) - Google Gemini (gemini.google.com, bard.google.com) - Perplexity (perplexity.ai) HOW IT WORKS 1. Install the Scanner from the Chrome Web Store 2. Use AI like you normally would — no signup, no login, no setup 3. The Scanner counts sensitive data in the background 4. Click the extension icon whenever you want to see your report 5. The popup shows your full breakdown: types of data, counts, and which platforms That's it. There is no step 6. PRIVACY (THE IMPORTANT PART) - All detection data stays on your device in chrome.storage.local - No backend, no server, no sync, no account - Zero network calls — ever - We cannot see your prompts or your detection counts - Uninstall the extension and the data is gone The Scanner is a self-contained Chrome extension. There is nothing for it to phone home to, because there is nothing it phones home to. You can verify this by inspecting the extension's source on the Chrome Web Store, or by monitoring network traffic in Chrome DevTools while using it. WHAT IT DOES NOT DO - Does NOT block sensitive data — the goal is visibility, not enforcement - Does NOT show pop-ups, warnings, or modals mid-conversation - Does NOT read AI responses or capture anything beyond detection counts - Does NOT upload, transmit, or share your data with anyone, including us WHO IT'S FOR - Engineers, analysts, and operators who use AI heavily at work - Security-conscious individuals who want a personal audit - Champions inside larger organizations who want to start a conversation about AI data practices - Anyone curious about their own AI usage habits OPEN ABOUT LIMITATIONS Pattern matching is imperfect. The Scanner may occasionally miss novel data formats or flag false positives. It's designed to be directionally accurate, not forensically precise — the goal is awareness, not enforcement. If you need active prevention rather than passive counting, see AegisPrompt for Teams — the enterprise version with real-time blocking, admin dashboards, and team rollout.
