Your toddler is choking on a grape.
Dinner. They went quiet. The cough is silent and they can't speak. You have about four minutes.
For kids 8+
You can save someone's life.
Zen will teach you how.
You don't need to be a grown-up to know what to do when someone falls, chokes, or stops breathing. Zen will read each step out loud and quiz you on it. Same words a paramedic would use, rewritten so they fit in your head.
For grown-ups
Zen Kids reads the same verbatim Red Cross / AHA / WHO protocol an adult would hear. The only difference is the Gemma 4 paraphrase prompt: it reframes each step for an 8-year-old to repeat back. The two-Gemma audit (26B paraphrase, 31B verifier, verbatim wins ties) is unchanged. Nothing is dumbed down — it's only made shorter.
Start with one of these
Your elderly mother just collapsed on the kitchen floor.
She is not breathing. She is on her back. You have to start before the ambulance arrives.
You cut yourself badly chopping vegetables.
The blood is steady, not spurting. Kitchen towel is the nearest fabric. You are home alone.
Your child is having a fever seizure.
They have been running hot all afternoon. Now their body has gone rigid. It looks like nothing you've seen.
Lessons follow verbatim Red Cross / AHA / WHO bystander first-aid protocols. Two Gemma 4 variants paraphrase and audit each step. Verbatim text wins any tie. Last reviewed 2026-05-16.
In a real emergency, call 999, 112, 911, 000, or 119 first. Then come back to Zen.
