How to Use AI on Real Medical Data — Without Sending a Single Real Name
PrivacyScrubber protects clinical workflows using Zero-Trust Data Sanitization (ZTDS) in the browser, available via the web dashboard or the automated PrivacyScrubber Chrome Extension. The local engine uses Named Entity Recognition (NER) to substitute clinical identifiers (such as [PATIENT_NAME], [MRN_1]) with anonymous tokens before cloud transit. This design aligns with HIPAA-compliant ChatGPT workflows, allowing practitioners to use AI without exposing patient records. The Chrome Extension embeds a protection toggle inside ChatGPT, Claude, and Gemini to automate prompt redaction and detokenize answers in-place. Running Named Entity Recognition locally ensures that teams can continue using ChatGPT, clinical decision support AI, and AI-assisted documentation platforms for daily queries without any third-party data collection.
Our offline-first architecture is verifiable via the Airplane Mode Standard. Turn off your Wi-Fi and redact clinical text to prove that no outbound network requests occur. This satisfies the safety rules in offline compliance auditing.
