ZensNoteRecord the lecture. Get the notes.
Listen to the lecturer instead of racing to copy slides. The AI lecture note taker records, transcribes and writes the notes for you.
Copying every slide while trying to follow the argument means doing two jobs badly. With ZensNote as your lecture note taker, you start a recording at the beginning of class and put your attention on the lecture itself. Afterwards the app transcribes what was said and writes a structured note: the topics in the order they were covered, the key points, and the terms the lecturer defined.
Lectures don't run in one clean block, so the recording doesn't have to either. Pause during the break, resume when the second half starts, and it stays one recording and one note. If the app closes or your phone runs out of battery partway through, the audio recorded so far is kept on the phone and ZensNote offers to recover it the next time you open it.
The note is where revision starts. Generate flashcards from the definitions, take a multiple-choice quiz with an explanation for every answer, or open the mind map to see how the week's topics fit together. When a concept still doesn't land, ask AI Chat to explain it using what the lecturer actually said.
Record each lecture and summarize it into the same notebook for that course, week after week. By the end of term you have a note for every session and a notebook summary across the whole module, a far better starting point for exam prep than a stack of half-finished handwritten pages.
One thing before you hit record: check your institution's and your lecturer's rules. Many allow recording for personal study; some ask you to get permission first.
Good for

Source: YouTube · How memory works · 12:30
Memories form in three steps, and sleep does more of the work than we think.
- Encoding: attention decides what gets stored at all; distraction cuts it short.
- Consolidation: during sleep the brain replays the day and moves memories into long-term storage.
- Retrieval: recalling something strengthens it more than reading it again.
Before and after
What went in
Excerpt from an illustrative first-year biology lecture: "Glycolysis happens in the cytoplasm and gives you a small net gain of ATP. The real payoff comes later, in the mitochondria, where the electron transport chain uses oxygen as the final electron acceptor. No oxygen, and cells fall back on fermentation, which is far less efficient."
What ZensNote gives you
Cellular respiration starts in the cytoplasm but makes most of its ATP in the mitochondria, and it depends on oxygen.
- Glycolysis: takes place in the cytoplasm, with a small net ATP gain.
- Electron transport chain: runs in the mitochondria, where most ATP is made.
- Oxygen: acts as the final electron acceptor in the chain.
- Without oxygen: cells switch to fermentation, which yields much less ATP.

How to use it
- 1
Check you can record
Make sure recording is allowed in the class, and ask if you're unsure.
- 2
Start recording in the app
Tap New Note, then Record, as the lecture begins.
- 3
Pause and resume
Pause in the break; it stays one recording.
- 4
Stop and get the note
When class ends, stop recording and ZensNote writes the summary and transcript.
- 5
Revise from it
Make flashcards and a quiz, or open the mind map.
Where it shines
Fast lecturers
When the slides move faster than you can write, the recording catches what you'd have missed.
Lectures in a second language
Read the summary afterwards at your own pace and check the transcript for words you didn't catch.
Lab briefings and seminars
Record the safety briefing or the seminar discussion and keep the steps and points in one note.
Exam season
Turn a term of lecture notes into quizzes and a notebook summary for the module.
Tips for better results
- 1Sit where the voice is clearNear the front, or near a speaker if the room uses a microphone. A clearer voice means a better transcript.
- 2Jot down what confused youA word on paper during class is enough. Ask AI Chat about it afterwards.
- 3One notebook per courseEach week's lecture then lands next to the others, ready for the notebook summary.
- 4Quiz yourself the next dayTaking the quiz a day after the lecture tells you more than taking it straight away.
Doing it yourself vs. ZensNote
| Doing it yourself | ZensNote | |
|---|---|---|
| During class | Copy slides, miss explanations | Listen while the app records |
| After class | Tidy up messy notes | Structured summary and transcript |
| A sentence you missed | Ask a classmate | Check the transcript |
| Exam prep | Rewrite notes into cards | Flashcards and a quiz ready to go |
Good to know
- Big halls with echo, or a quiet lecturer far from your phone, give a weaker transcript.
- Anything shown only on slides and never said aloud won't be in the note; snap the key slides with Image Scan if you need them.
- The transcript doesn't label speakers, so audience questions run together with the lecture.
FAQ
What is an AI lecture note taker?
An app that records a lecture and writes the notes for you. ZensNote records on your phone, transcribes the audio and creates a summary with study tools.
Can I record a lecture and summarize it later?
Yes. Record in class and stop when it ends; the note with the summary and transcript is made from that recording.
What happens if my phone dies during a lecture?
What was recorded so far is kept on the phone, and ZensNote offers to recover it next time you open the app.
Can I pause the recording during a break?
Yes. Hit pause whenever you like and carry on later — it all ends up in a single recording.
Can I upload a lecture recording instead?
Yes. Use Audio File to add an MP3, M4A, WAV, AAC or OGG recording.
Is it allowed to record lectures?
That depends on your institution and lecturer. Check the rules and ask for permission where needed.
How do I study from my lecture notes?
Use the quiz to find weak spots, flashcards to drill them, and the mind map to see how the topics connect.
