These are opinions from Hacker News comments, not medical advice. Talk to a doctor.

**Verdict:** Doctors recommend it as a fast medical reference that can replace UpToDate, though critics say generalist AI models outperform it.

## The badge

A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it. Health and money products are never badged.
