Oura is the best passive sleep tracker most people can buy. Its readiness and sleep scores are genuinely useful - and genuinely limited, because its meal photos, advisor and US-only lab panels all stop at the edge of Oura's own ecosystem — it can't read your NHS results, your supplement doses, or the fact you started creatine three weeks ago. Cuilvor sits above: it takes Oura's numbers (or your own words), your meals, your supplements and your lab results, and turns the whole picture into one short weekly review with at most two changes.

Yes - Oura's API can feed Cuilvor's database, and until then you can log sleep in plain words. Cuilvor is designed to read wearables, not replace them.
Oura Advisor sees what lives in Oura's ecosystem — ring data, meal photos, and US-only labs bought through Oura. Cuilvor reads everything from anywhere: any lab in any country (NHS screenshots included), supplements with dose and route, and your training — so it can say 'your ferritin trend explains the fatigue, see your GP' rather than advice bounded by one vendor's data.
No hardware. You bring your own AI key (Anthropic or OpenAI) so the intelligence runs on your account at cost price.
Each account's rows are isolated at the database level; AI keys are encrypted at rest; nothing is sold or shared. It's your record.
Your data is already telling the story. Cuilvor reads it.
