A personal medical analysis system for health problems that need a fresh look.
WhatDx helps patients and caregivers investigate complicated medical histories with a structured, continuing case analysis designed to complement—not replace—professional healthcare.
1. Why WhatDx exists
Difficult health problems rarely arrive as a neat, complete story. Symptoms evolve, reports accumulate, treatment responses change the picture, and different clinicians may see different parts of the case. WhatDx is designed to help keep that investigation coherent over time.
The service gives a patient or caregiver a structured way to bring together their history and records, answer focused follow-up questions, and revisit the same case analysis when new evidence appears.
2. How it works
Share your story and records. Tell WhatDx what has been happening and upload the reports you have.
WhatDx investigates the case. It reconstructs the timeline, studies the available evidence, looks for contradictions or missing pieces, and asks follow-up questions that may materially change the analysis direction.
Bring back new evidence. During the active research window, a new lab result, scan, specialist opinion or treatment response can be added to the same case so the investigation can be updated rather than restarted from scratch.
3. More than a general chatbot
WhatDx is not designed as a blank chat box waiting for the user to know the right prompt. It uses a physician-designed research process and can draw on multiple leading AI systems to examine different parts of a case. The exact underlying models may change as the technology improves.
The aim is not to produce a confident answer at any cost. The process is intended to preserve uncertainty, identify what does and does not fit, and help clarify which evidence may be most useful next.
4. A separate pathway for clinician-suggested cases
Clinicians can use WhatDx as a research fellow for selected complex cases. The patient answers targeted follow-up questions and shares records outside the consultation, while the final clinician-facing dossier is structured for rapid review.
See the dedicated WhatDx for clinicians page for patient selection, research-objective guidance, sample dossiers and referral tools.
5. Operator
WhatDx is operated by What dx, India. The broader team is not publicly listed at this stage while the service is in its initial production phase.

6. Medical boundaries
WhatDx is a research and information service. It is not a hospital, clinic, diagnostic laboratory, pharmacy or emergency service. It cannot perform a physical examination, independently verify every fact provided to it, prescribe treatment, or monitor a person in the real world.
AI systems can make mistakes. Important findings, hypotheses and suggested next steps should be reviewed with an appropriate healthcare professional. If you may be experiencing a medical emergency, seek immediate help from local emergency services or an appropriate healthcare provider.
