Native Personal Defense Against Model Ingestion

Pasting personal journal entries into AI chatbots can result in your private life being stored indefinitely in chat logs or used for model fine-tuning. PrivacyScrubber's browser extension intercepts inputs, substituting family names with [NAME_1] and addresses with [ADDRESS_1], allowing you to reflect and brainstorm with complete peace of mind.

Personal Reflection & Life Planning Workflow

    Copy or Paste Unsanitized Content: User pastes personal reflection discussing conflicts with family members and specific financial debt figures.
  2. 2
    Real-Time In-Browser Sanitization: The extension masks family names into [FAMILY_MEMBER_1] while leaving emotional context and personal goals untouched.
  3. 3
    Submit to LLM with Zero Cloud Exposure: User asks ChatGPT: "Help me structure a constructive conversation with [FAMILY_MEMBER_1] regarding financial boundaries".
  4. 4
    Instant Local Reversal (Contextual Reveal): User clicks Reveal in the floating popover to restore real names on-screen for comfortable reading.
