The Intelligence Behind Every Rep
Most fitness software is a database with buttons. Harley is powered by the DNAi Systems, over 100 million verified data points across exercise science, nutrition, medical, finance, and academic domains, each structured with a Name, a Form, and a Dharma. Every data point is cryptographically hashed and sealed. No single fact can vouch for itself, every recommendation requires a second, independent source to validate it, like a surgeon who can't operate without an anesthesiologist confirming it's safe to proceed.
Built by a psychiatrist and a pediatrician who needed AI they could trust with patients' lives. The same peer-reviewed foundation that powers medical AI now powers your training business.
Why “Harley”?
Harley is named after a rescue pitbull, the sweetest dog you'll ever meet, who never misses a session at Edwin's gym. Always there, always patient, always on your side. Recovery, resilience, persistence. One more rep.
