Exam coming up and you have not gone through everything?
We collect your materials and lectures.
It learns how you study, and studies with you for the exam.
A Chrome extension that transcribes the lecture in real time, in class, on Zoom or Meet, and keeps it sorted by course. B Notes learns from past exams, your files and the lectures what really matters, and each time you open it says what to do now: what to study, how long, and why.
Takes half a minute. 3 free hours of transcription, no credit card.

The night before the exam there is no time to replay three hours of recording.
Versus the alternatives
ChatGPT was not in the lecture. NotebookLM only knows files you upload, and cites a passage in a document, not a moment in the lecture. Otter transcribes and stops there. B Notes records by itself, answers only from your lecture with a jump to the second, and if it is not in the material, it says so.
| Versus the alternatives | B Notes | ChatGPT | NotebookLM | Otter |
|---|---|---|---|---|
| Knows what your lecturer said | Records in class, Zoom, Meet and YouTube | Was not in the lecture | Only files you upload | Transcript only |
| A citation that jumps to the second | Yes, to the exact second | None | To a passage in a document | None |
| Says “not in the material” instead of inventing | Yes | No | Inconsistent | None |
| Mixed Hebrew and English in a live lecture | Yes | Not in a live lecture | Not in a live lecture | Not in Hebrew |
| Learns from past exams what matters and says what to study now | Yes, with time and reason | No | No | No |
From the lecture to the exam in four steps
- Add to Chrome
Press “transcribe the lecture” and stop thinking about it
The extension transcribes in real time in class, on Zoom, Meet or YouTube, detects headings and syncs to your personal area. At night you can let it transcribe the recordings of a whole course.
The lecture is waiting, organized, in your personal area
Transcript, summary and headings for every lecture, by course, without uploading anything.
Ask, and get an answer with a citation
The citation jumps to the exact second in the lecture. And if it is not in the material, B Notes says so and never makes it up.
Every visit, one action: what now
B Notes learns from past exams, your files and the lectures what matters, and suggests a review, practice or what to do in the time left before the exam, with how long it takes and why this one. No grade, no comparison with others.

Introduction to statistics · example lecture
The main idea, without hunting through notes.
A relationship is a start. Not proof.
Correlation describes a relationship between two variables.
A relationship does not establish that one variable causes the other.
To assess causation, consider other possible explanations.
