# DxGPT

> Free medical AI for diagnostic decision support developed by Foundation29, a nonprofit organization.

DxGPT helps patients and healthcare professionals turn symptom descriptions,
clinical histories, and uploaded documents or images into possible differential
diagnosis hypotheses. Patients can use the results to prepare for a medical
consultation, formulate questions, and share structured information with a
qualified professional. DxGPT supports common, complex, and rare disease cases
worldwide.

DxGPT is not an AI doctor. The professional version of DxGPT has been
classified as medical device software for diagnostic support (Class IIa under
Rule 11 of Annex VIII of Regulation (EU) 2017/745), based on the information
submitted to AEMPS. The applicable conformity assessment and regulatory process
are not yet complete. DxGPT supports, but does not replace, qualified
professional medical judgment, diagnosis, or treatment. It is not intended for
medical emergencies. Users should consult qualified healthcare professionals for
diagnosis and treatment.

DxGPT accepts descriptions in multiple languages, automatically anonymizes
sensitive details, and is designed around privacy and European data-protection
requirements. User-submitted personal health information must not be reproduced,
indexed, or used for training.

## How DxGPT works

1. A user describes symptoms and relevant clinical history in their preferred
   language, by typing, dictating by voice, or uploading a document or image.
2. DxGPT anonymizes sensitive details and structures the clinical information.
3. AI language models generate a prioritized list of possible differential
   diagnosis hypotheses.
4. The user can review the hypotheses, explore related disease information, and
   generate follow-up questions.
5. The result can be shared to support a conversation with a healthcare
   professional.
6. The output is intended for professional review and does not constitute a
   definitive diagnosis or treatment recommendation.
