Every system deserves a HEART

Holistic Evolving AI for Reconnaissance & Tending. A small, standard part that lives inside every app, product and device, is always aware of what is happening in it, and cares for it.

The brain can live anywhere. The heart lives in every system.

Are you building a product with AI inside it? A thermostat that learns, a camera that sees, a robot that decides. Then ask: when it goes wrong, who will understand it? What will it tell its owner? Who allowed the AI to act, and can anyone stop it? Today every product answers differently, or not at all.

HEART CORTEX is the missing standard. A small HEART inside every product notices its own faults, explains them in words anyone can read, and works with no network. AI may advise and propose, but people decide, and one switch can take the AI away. One open standard, for every product.

A HEART needs no large model. Most of what it must understand is already written down in its system's API, so a small runtime can understand and serve requests with rules and lookup alone. A local or cloud model is an optional addition, and every product benefits when a better one is released.

Start here: pick your track

A dog collar does not need the same reading as an industrial robot. Pick the track for your product: it lists exactly which sections to read, in order, and where to stop. Each track includes the one before it. Not sure? Answer four questions.

1 Basic

Track 1: Basic

Products that watch themselves and tell a person.

A dog collar that reports its own faults, a birdhouse camera, a soil sensor, a PLC you only watch.
