The Brain, by Vidya

Your professor's teaching. On call at 2 a.m.

A professor builds a Brain from their own material. Vidya answers with it: their approach, their notation, their citations. And when the course hasn't covered something, it refuses honestly and routes the question back to them.

How a Brain is built

The professor teaches it once.

Not a chatbot pointed at a PDF folder. A Brain is built with the professor, from their material, and it never speaks until it has earned their trust.

01

Upload everything.

Syllabus, lectures, notes, slides, past exams. The professor dumps it all in; the Brain studies the course the way a devoted TA would.

02

It learns how they teach.

A short interview captures what the material can't: the professor's way of explaining, their notation, how much to hint before revealing, what matters most this term.

03

Verified before it speaks.

The Brain must pass the professor's own verification test before a single student sees it. If it can't answer faithfully, it doesn't publish.

The contract

Every answer cited. Or an honest refusal.

A confident wrong answer under a professor's name is the one failure this product exists to prevent. Watch the contract at work.

When it knowsGrounded, in their voice.

The answer comes from approved course material, phrased the way this professor teaches it, with receipts. Tap a citation and you're looking at the lecture minute it came from.

Microeconomics · Week 9
Why does marginal-cost pricing break down when fixed costs are huge?
Your professor's course Price at marginal cost and you never recover the fixed costs you already sank; that's why lecture treated it as a second-best problem, not a broken model. Lecture 9, 12:40Notes, ch. 6
Is congestion pricing on the final?
Not covered in your course. Yet. Your professor hasn't taught congestion pricing. I won't guess under their name. Your question just went to their queue.
Professor notified. 14 students hit this wall this week.

When it doesn'tIt says so. Out loud.

No improvising, no "probably." The refusal is labelled, the question goes to the professor's queue, and the student knows exactly where they stand. Honesty is the feature.

For the professor

See where the class is stuck. Never who.

Refusals and repeated questions roll up into one view no professor has ever been handed before: what the class actually needs next, with every student's identity behind a privacy wall.

One answer teaches the whole class.

A student hits a wall.

The Brain refuses honestly: the question isn't covered by the course yet. That refusal is a signal, not a failure.

The professor answers once.

The question lands in their queue. They answer it the way only they can: a minute of their time, on their terms.

The Brain learns it forever.

Once approved, the answer joins the course material. Every student who hits that wall after tonight walks straight through it.

The Brain doesn't replace the professor. It multiplies them, and sends the hard questions home.

Voice · In development

Now imagine it can speak.

Voice gives the Brain a mouth. Not a generic assistant voice: the professor's complete persona. How they explain, how they pause, the way they steady you before a hard step. Cloned with their consent, carried by Vidya, awake long after office hours end.

"Why does entropy always win?"

Ask your professor out loud, on the walk home. Answered in the voice that taught the course.
