  • DxGPT (dxgpt.app): Free AI tool using GPT-5 mini. Input symptoms for prioritized DDx list. Pros: Instant, multilingual, GDPR-compliant, no login for basics. Cons: Less clinically validated than Isabel. Ideal for quick checks or students.

  • Vera Health or Glass Health: Top AI per 2026 Clinical AI Report (Vera: 90/100). Pros: Evidence-based, integrates labs/history. Cons: Paid enterprise (~$20-50/mo). Great for comprehensive workflows.
