Why we built Cortez AI around four parts, not one prompt

Most products calling themselves an "AI agent" are a single chat window with a clever system prompt behind it. That works for a demo. It falls apart the moment someone asks it something that isn't in the prompt, or expects it to actually do something rather than describe doing something.

We started from a simpler question: what is an agent actually made of? Strip away the marketing and you get four honest parts. A model to reason with. A memory pulled from documents you actually own, not the open internet. A set of tools connected to accounts you already use. And a channel — a place the finished thing actually lives, whether that's a link, an embed, or an API call.

Building Cortez AI around those four parts, instead of one long prompt, means every piece is visible and configurable on its own. You can see exactly which document a reply was pulled from. You can grant read access to Gmail without granting send access. You can swap the model provider without touching anything else. Nothing is a black box, because nothing needs to be.
