Am I allowed to record my lectures?

It depends on your institution and your lecturer. Many allow personal recordings for study; some ask you to get permission first. Check your course policy or ask the lecturer. The in-app recorder reminds you before it starts.

Will it hear the lecturer from the middle of the room?

A phone on the desk in the first few rows works well. Background chatter and fan hum are cleaned up, and if a stretch is genuinely inaudible the notes say so instead of filling the gap.

Does it tell the lecturer apart from students' questions?

Not yet: the transcript doesn't label who is speaking. Questions asked in the room are still captured in the transcript and notes.

Use case · Class recordings

Listen in class. We'll take the notes

Put your phone on the desk and hit record. After class, get detailed notes of everything the lecturer taught, each line linked to the moment it was said, plus every homework, reading and exam date they mentioned on the way out.

As detailed as the class

Not a summary. Every topic, worked example and aside, in the order it was taught, with a timestamp to jump back to the bit you missed while copying the board.

Deadlines, caught in passing

“Problem set 5 is due Friday”, said as everyone packs up, lands in Tasks & deadlines. If no date was given, it says Not mentioned instead of guessing one.

The audio doesn't hang around

Turn on “Delete originals after processing” in Settings and the audio is deleted once your notes are made; the notes and transcript stay. The recorder reminds you to check that recording is allowed.

1. What elasticity measures1:50

Price elasticity of demand (PED) is the percentage change in quantity demanded divided by the percentage change in price. It has no units, so you can compare how buyers react to coffee prices with how they react to petrol.

2. The midpoint method8:15

PED = (ΔQ ÷ average Q) ÷ (ΔP ÷ average P). Using averages gives the same answer whether the price rises or falls. 9:02
Worked example from the board: price ₹40 → ₹60, cups sold 100 → 60. PED = (−40 ÷ 80) ÷ (20 ÷ 50) = −1.25, so demand is elastic. 12:40
Quote the absolute value: above 1 is elastic, below 1 is inelastic, exactly 1 is unit elastic. 15:10

3. What makes demand elastic21:30

Close substitutes: one brand of tea is elastic, tea in general is not. 22:05
A big share of the budget, like rent or a scooter. 24:48
Time: people find alternatives to petrol over years, not days. 27:20

4. Elasticity and total revenue34:00

Elastic demand: a price cut raises total revenue. Inelastic demand: a price rise does. 35:12
Student question: why can farmers earn less after a bumper harvest? Because food demand is inelastic, the price falls by more than quantity rises. 41:30

Flagged by the lecturer

“The total-revenue test is on the midterm every year. Be able to argue it in both directions.”

002 · How it works

Three steps. No note-taking.

Hit record in class

Open the app on your phone or laptop and leave it on the desk. It keeps recording with the screen off, up to 6 hours on Pro. Or upload a voice memo afterwards.

Pick Lecture

Or let auto-detect choose. Detailed notes, revision points, flashcards, a quiz, a glossary and Tasks & deadlines are on by default.

Review after class

Skim the notes on the way home, jump to any timestamp that's unclear, and tick off tasks from every course in one list.

Lecture recorder: questions

The things people usually ask before their first upload.

It depends on your institution and your lecturer. Many allow personal recordings for study; some ask you to get permission first. Check your course policy or ask the lecturer. The in-app recorder reminds you before it starts.
A phone on the desk in the first few rows works well. Background chatter and fan hum are cleaned up, and if a stretch is genuinely inaudible the notes say so instead of filling the gap.
Not yet: the transcript doesn't label who is speaking. Questions asked in the room are still captured in the transcript and notes.
By default it's kept with the note so you can replay any moment. Turn on “Delete originals after processing” in Settings and the audio is deleted once your notes are made, while your notes, transcript and tasks stay.
