The health system today gets paid when you get sick. Hospitals, visits, and pharmacies all run on the engine of illness.
  Nobody is paid to keep you well.                                                                                             
                                                         
  I built Health Companion because, sitting at fifty, watching my parents age, I realized the product I needed didn't exist. It
   is a wellness companion whose only job is to keep people well, in the language they actually speak. Powered by Opus 4.7 —
  extended thinking exposed as an opt-in clinical audit layer any user can open, multimodal reading of lab reports,            
  prescription labels, and smartwatch screens with no OCR in between, and a living state document that compounds with every
  conversation. It never diagnoses, never prescribes, always refers. A practicing physician — me — authors and reviews every
  clinical string.

  Where care is scarce, the value rises: someone without a family doctor now has a digital one. Especially in places like      
  México. Most health products live around the visit. This one lives between visits — in the years when nothing is happening
  yet, the years that decide everything.                                                                                       
                                                         
  Built in five nights with Opus 4.7 and a coordinated team of Claude Code subagents. Open source, Apache 2.0.
