Simeon

Technical documentation

How Simeon is built, written up for anyone making something like it.

Part of Simeon's mission is making better learning products for everyone. So I share what I've built, and what I learned building it, in the hope that it saves you some time on your own.

How a plan is built
From a Canvas course to a checked study plan: the export, the engine with no AI, the agent's eight steps, the checks run by plain code, and what a build costs.
