Transcribe a 90-minute lecture and study from the words, not the replay.
A 90-minute lecture is 90 minutes of audio, and it comes back as searchable text in about 3 minutes, with the first 20 minutes free as a preview. The $6 pack of 500 minutes finishes it and holds five lectures of that length, with 50 minutes left after the fifth.
What 90 minutes of lecturing becomes
One teaching block, back as notes before the next class starts.
The usual 90-minute recording
The standard university slot is often an hour and a half, recorded on a phone in the front rows, a laptop at the desk or the hall's lecture capture. Use the lecture capture copy only where the lecturer lets students download it; a phone recording of your own seat works just as well.
Minutes in, minutes left
At about 2 minutes per audio hour, 90 minutes is ready in roughly 3. On the $6 pack the lecture uses 90 of 500 minutes and leaves 410. Five lectures use 450, so a week of a heavy timetable fits one pack with 50 minutes in hand.
Topics you can revise by
Lecturers tend to move through three or four ideas in a 90-minute block. Each becomes a chapter with a start time, and the brief lists the questions the lecture answers, which work as flashcards the night before an exam. The full transcript sits behind upload page in your Library.
Find the term, not the minute
Search the transcript for a word the lecturer used once, or ask the chat what was said about it. The answer quotes the lecture and gives the timestamp, so you can play the ten seconds around it to hear the emphasis.
Why an hour and a half is easy to lose
Ninety minutes is long enough to drift and short enough to skip.
✗ Revising from the recording
The audio is there, but finding one definition in 90 minutes means listening to most of it again.
- Replaying a whole block for one example
- Gaps in notes where you were copying a slide
- Questions from the room you could not hear
- No search across a term's lectures
- Free tools that stop after the first stretch
- A pile of recordings never reopened
✓ Revising from the lecture text
Each lecture comes back as a document you can search, skim and quote.
- About 3 minutes per lecture
- The first 20 minutes free to judge the text
- 410 minutes left after one lecture
- Chapters with timestamps for each idea
- Exam-style questions drawn from the brief
- DOCX that drops into your notes app

FAQ
90-minute lectures, the common questions.
How fast is a 90-minute lecture transcribed?
About 3 minutes. The pace is roughly 2 minutes per hour of audio, and the published runs on our proof page go as far as 9.31 hours in 1,033 seconds.
How much is a term of 90-minute lectures?
One lecture uses 90 of the 500 minutes in the $6 pack. A course with one 90-minute lecture a week for 13 weeks is 1,170 minutes, which fits the $12 pack of 2,000 with 830 left. Two lectures a week for 13 weeks is 2,340 minutes, which belongs on the $24 pack of 5,000. For comparison, 100 minutes, the length we see most among paying uploads, leaves 400 on the $6 pack, and five of those fit it.
How large is a 90-minute lecture recording?
Audio at 128 kbps for 5,400 seconds is 691 megabits, about 86 MB; a phone voice memo at 64 kbps is about half that. Lecture capture video is larger and varies with the slides. Files up to 2 GB upload before a pack, up to 5 GB after one.
Should the lecture be cut into parts first?
No. One file can run up to 10 hours or 5 GB, so a 90-minute lecture, or a whole day of them recorded back to back, goes in as it is.
The lecture is not in English. Will it work?
99 languages are detected automatically, Korean, Japanese, Portuguese, Spanish and Swedish among them. A lecture that switches language is detected on its main language, and English with Tagalog in one recording is handled.
What can I download, and who sees the recording?
TXT and DOCX for notes, SRT and VTT for captions, JSON for anything else. Recordings are transcribed on our own servers and are never used for training.
