TeenBuddy
A daily companion for teenagers, with the safety system designed in first.
TeenBuddy helps teenagers manage emotions, resist unhealthy impulses, build habits and ask for help. Six screens: home, check-in, help now, learn, journal and profile.
The interesting constraint is that an AI coach talking to teenagers about their worst days cannot be allowed to improvise. The model is kept inside deterministic rails, risk is classified in two tiers, and crisis responses come from reviewed templates with region-aware resources rather than from generation.
Safety was built from the first commit rather than bolted on, and it is measured: a labelled safety corpus and a model-judged coach rubric run alongside the ordinary test suite.
How it is built
- Two-tier risk classification with reviewed crisis templates, not generated crisis text.
- 440 deterministic gate tests that run in about two seconds at zero cost.
- A 42-case labelled safety corpus plus a model-judged rubric for the coach.
- 25 lessons, a 28-day challenge rotation and 8 coping interventions as structured content.
- Runs with no configuration — no account, no Firebase project, no API key needed to start it.
