Agora
For instructors

A week with Agora

Agora runs on the materials you already teach with and the schedule you already keep. Here is the whole loop: what you do, what your students do, and what lands on your desk, for one ordinary week.

Share what you already teach

Slides, lecture notes, readings, problem sets, as they are, with no reformatting. Glo’s questions come from what you actually taught rather than a generic curriculum.

Anything you mark instructor-only, such as solutions, answer keys and exams, is kept out of what Glo can draw on in a conversation with a student.

What the student actually does

They talk. Glo opens with a question, listens to the whole answer, and asks the next one out of what they just said. There is no typing and nothing to paste, which is the entire point.

Glo

On the problem set you found that the amplitude of the damped oscillator decays exponentially. Why exponentially, rather than linearly?

Problem set 42. A block of mass m on a spring of constant k movesthrough a viscous fluid, so the damping force is −b·v.m d²x/dt² + b dx/dt + k x = 0m(a) Show the amplitude decays exponentially, and findthe decay constant in terms of b and m.
Problem set 4, question 2

You

Because the damping force goes with velocity, so the energy you lose each cycle is proportional to the energy you still have…

Glo

Right. Your professor drew that envelope in Thursday’s lecture and said it was the part to remember. It only holds under one condition. Which one?

You

The damping has to be light? Otherwise it doesn’t really oscillate, it just creeps back to zero.

Glo

Good. Now tie that back to the resonance curve you derived in week two. What happens to the peak as the damping grows?

Resonancep. 8ωAω₀less dampingA(ω) = (F₀/m) / √((ω₀² − ω²)² + (γω)²)

What it asks of you

Honestly: not much. Share your materials once, glance at the generated review each week, and read the class report. Every judgment Agora reaches carries the student’s own words behind it, and how we keep that checkable is laid out in Trust & Security. You stay the judge; Agora does the listening you don’t have hours for.

See it with your own course

Agora is in pilot in fall 2026 courses at Harvard and MIT. Bring one course and we’ll set up your first weekly review with you, shaping it around what your classroom needs.
