01 — Taught by their protagonists
The syllabus,
in the first person.
Nobody knows what Newton sounded like. That’s the point — this is one thing that only became possible now.

The Republic, explained by Plato
Explore course ↗Anatomy, explained by Leonardo
Explore course ↗These are dramatizations, not recordings. Every anachronism is marked out loud. Voices are synthetic and invented: we never clone a real one.
02 — Guided journeys
Pick a direction.
We map the way.
A path connects courses into one argument, then ends with an exam that measures what stayed with you.
03 — Inside a lesson
The video stops
and asks you something.
A checkpoint interrupts passive watching at the exact moment a concept matters.
If gravity pulls the Moon toward Earth, what keeps it in orbit?
04 — The live library
Every course starts
with a real question.
These cards come from the published catalog, not a marketing mockup.
05 — Exams & certificates
A certificate you earn
by passing, not by
pressing play.

07 — How the courses are made
We’d rather tell you
than have you guess.
Most courses here are produced with AI: a model writes the script, a different model audits it against an accuracy rubric, and the narration is a synthetic voice. That’s why this costs a dollar instead of thirty.
Premium courses are different. Someone who does the thing for a living reads the script, rewrites what’s wrong, and signs it.
