Automatically detect and mask sensitive data before pasting into AI chat interfaces. WHY PASTEGUARD? Every time you send a message to an AI chatbot, you risk exposing sensitive data — emails, phone numbers, credit cards, API keys. PasteGuard detects them automatically, lets you review and control what gets masked, and replaces only the confirmed items when you hit Send. The AI never sees your real data. You read the response normally. HOW IT WORKS Paste or type a message — PasteGuard detects sensitive data instantly using local pattern matching A review panel shows every detected item with a toggle. Turn off any false positives Press Enter or click Send — only the toggled-on items are replaced with neutral placeholders like [EMAIL_1] When the AI responds with a placeholder, PasteGuard restores the real value highlighted in context WHAT IT PROTECTS Free tier: • Email addresses • Phone numbers (international formats) • Credit card numbers Pro / Business tier (all of the above, plus): • Social Security Numbers (SSN) • API keys & tokens (sk-, pk-, ghp_, AIza, AKIA…) • IP addresses • IBAN codes (all EU countries) • Italian fiscal codes • Manual custom selection — highlight any word and censor it on the spot SUPPORTED PLATFORMS • ChatGPT (chatgpt.com) • Claude (claude.ai) • Google Gemini (gemini.google.com) PRIVACY FIRST Zero servers.
