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. ---

Thanks for sharing this, @Schmallo. This is a thoughtful suggestion, especially for healthcare, legal, forensic, and public-sector use cases where re-identification risks matter. Part of this is already supported in healthcare through [ChatGPT Health](https://openai.com/index/introducing-chatgpt-health/), which includes additional privacy protections and keeps health conversations separate from model training. For organizations, [ChatGPT Business and Enterprise](https://openai.com/business-data/) also provide strong data privacy controls and don't train on business data by default. That said, the specific idea of **local anonymization and pseudonymization before any data is uploaded** isn't broadly available today, particularly for legal and forensic workflows. That feels like a distinct gap and a useful feature request. We're sending this to the team for logging so it can be considered alongside similar privacy-focused feedback. -Mark G. ---
