The AI Connection: An Optional Bonus

PrivacyPromptAI also integrates with AI tools, but this is a bonus feature, not the core product. The Chrome extension (SecurePrompt) lets you clean text directly inside ChatGPT, Claude, or Gemini before you send a prompt. It intercepts your text before it reaches the AI platform, removes any PII, and lets you review the cleaned version first.

This AI integration is only available through the browser extension. The main website works completely independently, you don't need to use any AI tool to benefit from PrivacyPromptAI.
