Longitudinal wave — needs a medium to travel.
f = 1/T — higher frequency, higher pitch.
v = f × λ ≈ 343 m/s in air.

The problem

Listening and writing don't mix

Taking good notes in a live class is nearly impossible — for teachers trying to teach and students trying to keep up.

You can't write and listen

Scribbling notes means missing what the teacher says next. Understanding suffers either way.

Miss one class, lose the thread

Sick, late, or double-booked? A single missed lecture leaves a gap that's hard to fill.

Messy notes nobody reviews

Half-finished, hard to read, scattered across notebooks — most notes never help at exam time.

How it works

Record. Relax. Review.

From a noisy lecture hall to polished study notes in three steps.

01

Hit record

Tap once. Every word captured — even in noisy rooms.

02

AI does the work

AI pulls out topics, key terms & definitions.

03

Get clean notes

Clean notes, summaries & flashcards in minutes.
