Product summary
Review the store description, core capabilities, and common use cases.
The AI tools you use every day can use your prompts to train their models. Every client name, API key, or Personally Identifiable Information you send is potential training data.
PromptMask stops that.
WORKS WITH: ChatGPT · Claude · Gemini · Perplexity · Grok
It intercepts your prompt before you hit send, runs an on-device AI model entirely in your browser, and replaces sensitive data with labeled placeholders like [NAME 1] or [EMAIL 1]. The AI still gets the full context of your request. Your data never leaves your machine.
WHAT GETS REDACTED
Names, emails, phone numbers, addresses · SSNs and government IDs · Credit cards and bank details · Medical record numbers and insurance IDs · API keys, tokens, and passwords · IP addresses and device identifiers · Order IDs, invoice numbers, case references
