ReadyStrike AI Prompt Guard

Catches private info before it's sent to AI chats like ChatGPT, Claude & Gemini. Warn, block, or mask it. Local-only.

What it does ReadyStrike AI Prompt Guard watches what you type or paste into AI chat sites and catches private information before it's sent. Passwords, API keys, Social Security and credit card numbers, phone numbers, home addresses, and more are detected the instant they appear — and the extension can warn you, block the message, or mask the sensitive part so the chat keeps working without the private data. Why install it People share far more with AI tools than they realize. A pasted config file, a customer's details, a kid typing their address into a chatbot — once it's sent, it's gone. AI Prompt Guard puts a safety check between you and the AI. Key features - Catches secrets, IDs, financial data, and personal info as you type or paste - Three responses you control: warn, block, or mask (e.g. 408-XXX-XXXX) - Smart masking keeps the chat useful while hiding the private part - A simple "kid safety" category for age, school, "home alone," and meet-up phrasing - Private by design: your prompts and history stay on your device — nothing is sent to us - Optional email/webhook alert to a parent or guardian when something is shared - Tune what counts as private, and add your own words and patterns Privacy Everything runs locally in your browser. ReadyStrike does not receive your prompts, your history, or any personal information. Alerts go only to a destination you choose. Sensitive values are stored masked, never in the clear. Works on ChatGPT, Claude, Gemini, Copilot, and Perplexity. Made by ReadyStrike.
