What Zen is
A calm coach today. A first-aid coach when it matters.
Daily focus, chronic-pain logging, anxiety grounding. The same voice you hear thirty times a month walks you through CPR or choking when the moment is real. Voice-first, 100+ languages, works offline.
“Someone collapsed and is not breathing.”
Verbatim Red Cross step plays in Charon voice within 50 ms. Verifier badge confirms the second model agrees.
The evidence
Four documented reasons the bystander doesn't act.
Language. A US study of 9-1-1 calls found callers with limited English proficiency received bystander CPR in 64.3% of cases versus 77.5% for English-fluent callers, with dispatchers taking longer to recognise the arrest and instructions arriving too late to follow (Bradley et al., 2011). The taxi driver who finds a passenger collapsed in the back seat is the bystander these numbers describe.
Setting. Across studies of kindergarten teachers, only around 37% knew the choking protocol while over 40% had already faced a choking child in school. Roughly half of paediatric choking deaths occur with no bystander action taken at all (Riyadh kindergarten study, 2024; narrative review of choking first aid, 2024). The bystander is in the room; the protocol is in a binder.
Connectivity. In rural Kerala, 44% of the population has no internet access. A buffering YouTube tutorial does not load before the four-minute brain-damage window closes (rural India connectivity survey, 2021). The bystander has the phone but no signal.
Equity, even when everything else works. Black and Hispanic cardiac-arrest victims in the United States are dramatically less likely to receive bystander CPR (38.5% versus 47.4% in home settings; Garcia et al., NEJM 2022) regardless of neighbourhood composition. Even a perfectly connected, English-fluent bystander often does not act.
Zen is built against these four gaps directly: 100+ language voice, verbatim Red Cross / AHA / WHO protocols, offline-first, free at point of use.
