The Digital Twin, by Vidya

Your course. On call at 2 a.m.

A professor builds a Digital Twin from their own course material. Students ask it anything, out loud or typed, at any hour, and it answers the way that professor teaches, with every source cited. When the course hasn't covered something, it says so and sends the question to the professor.

How a Digital Twin is built

The professor teaches it once.

Not a chatbot pointed at a PDF folder. A Digital Twin 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 Digital Twin 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 Digital Twin 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 professor's view on a phone: her CEM 141 Twin, live for 312 students, 48 of 50 test questions right, 96 percent. Going live needs 90 percent, checked every night.
Verified before it speaks

It sits the professor's own test. Every night.

The professor writes the questions. The Digital Twin has to answer them from the course, faithfully, before any student sees it. Below 90 percent, it does not go live.

From the Vidya app.

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 slide it came from.

Dr. Okafor's Twin on a phone explains why a catalyst doesn't change K, citing Lecture 9 slides 21 and 22 and Notes 14.3, then 'Memory updated: studies chemistry best with analogies first, then the math.'

When it doesn'tIt says so. Out loud.

No improvising, no "probably." The refusal is labelled, the question goes to the professor, 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.

Dr. Okafor's dashboard on a laptop: six things need her. Where students are stuck this week: 412 questions, 91 percent answered from her material. Le Chatelier with catalysts, 41 questions; Gibbs free energy of mixing, 28, not in her material, so the Twin sent them to her; ICE tables, 19. Her CEM 141 Twin is live, 48 of 50 test questions right.
The professor's view, at a desk. Topics and counts, never names.
The correction loop

One answer teaches the whole class.

A student hits a wall.

The Digital Twin 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 Digital Twin learns it forever.

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

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

The professor's viewone reply, in her voice

Answered once. Out loud.

Twenty-three students asked the same thing twenty-three ways. The professor records one reply in their own voice. Every student hears it, with a transcript, and the Digital Twin keeps it for whoever asks next.

Voice · in development

Now imagine it can speak.

Voice gives the Digital Twin 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.
