Automatically masks API keys, emails, financial records, and confidential secrets before they reach ChatGPT, Claude, and Gemini. PromptShield masks sensitive data in your prompts before they reach ChatGPT, Claude, and Gemini. It's easy to paste an API key, a customer's email, or a card number into an AI chat. PromptShield spots them as you type and replaces them with placeholders like [REDACTED_EMAIL_1], so the AI gets your question without your private data.
