HASH Track II — what we learned
Building contraceptive decision support with clinicians in the loop from day one.
- Field notes
HASH Track II pushed us to show a working prototype, not a slide deck. We integrated WHO MEC screening, multilingual intake, and a CHW confirmation workflow early because judges — and more importantly, future users — needed to see safety and usability together.
The lesson we carry forward: evidence for AI in family planning will come from instrumented pilots with clear outcomes, not from model metrics alone.
