Local anonymization mode for confidential documents before upload

ChatGPT should offer a local preprocessing/anonymization mode for sensitive documents, especially medical, legal and forensic documents. The mode should detect and pseudonymize names, dates of birth, addresses, file numbers, hospital IDs, rare location/time combinations, image metadata and other re-identification risks before any content is uploaded to OpenAI servers. This would be highly relevant for physicians, legal professionals, researchers and public institutions working with confidential records.
