AI Prompt Security - Protect your sensitive data when using ChatGPT and other AI models. Boundary is an AI prompt security extension that automatically detects and redacts sensitive information from your prompts before they are sent to AI assistants — helping keep personal, financial, and professional data private. Every time you type a message, Boundary scans it in the background and removes information that should not leave your device. No manual sanitizing or copy-pasting required. ─── WHAT BOUNDARY PROTECTS ─── Personal Information Emails, phone numbers, home addresses, dates of birth, passport numbers, government IDs, tax IDs, Social Security numbers, GPS coordinates, and more. Financial Data Credit and debit card numbers, CVV, expiry dates, bank account numbers, IBAN, SWIFT/BIC, routing numbers, crypto wallet addresses, and payment identifiers. API Keys & Secrets API keys, access tokens, JWTs, bearer tokens, database connection strings, private keys, credentials, and environment variables such as PASSWORD or SECRET. Prompt Injection & Malicious Input Boundary detects common prompt injection attempts and suspicious patterns designed to manipulate AI systems or expose sensitive context. ─── PLANS ─── Basic (Free) All redaction runs locally on your device using fast pattern-based detection. Your prompts are not uploaded or stored. Pro Adds custom redaction rules and advanced context-aware detection for identifying sensitive information that may not follow standard formats. ─── PRIVACY FIRST ─── Boundary does not store your prompts or sell your data. Local protection runs entirely on-device. The extension only connects to our servers for authentication, usage metrics, and optional advanced analysis features. Built for developers, teams, professionals, and anyone who uses AI tools and wants stronger protection for sensitive information.
