Brain. Senses. Hands. Heart. Body. — Five organs for an AI clone that lives in the cloud.

It emails me a morning brief at 6:30 AM, triages my inbox at 4 AM, and searches 500+ pages of my knowledge in under a second. Three clients. One brain. Zero dollars.

A Little Girl in a Hospital Waiting Room, with a Folder Full of Medical Records. Can Interop 2.0 Help Her?

A Little Girl in a Hospital Waiting Room, with a Folder Full of Medical Records. Can Interop 2.0 Help Her?
