Transcribe online lecture (인강) recordings a whole course of them, in Korean.
A saved online lecture (인강) of 1 to 2 hours comes back as Korean text in about 2 to 4 minutes, and the first 20 minutes are free. A course of 40 lectures at 90 minutes each is 3,600 minutes and fits the $24 pack of 5,000 minutes, priced in US dollars.
For students working through a course
Forty lectures are too many to replay. Forty transcripts can be searched in seconds.
Lectures you may download
Many online lecture services stream inside their own player and do not allow downloads, so transcribe only lectures you are permitted to keep or recordings you made yourself with permission. A lecture posted publicly on YouTube can be pasted as a link instead.
One file per lecture
Upload each lecture as its own file so the chapters and timestamps match that lecture. The brief at the top states what the lecture covered, and the chapters let you jump to a single unit when revising.
A course, counted
Forty 90-minute lectures make 3,600 minutes on the $24 pack of 5,000, with 1,400 left for the next course. A shorter course of 20 one-hour lectures is 1,200 minutes on the $12 pack of 2,000.
Search all forty lectures
When you cannot remember which lecture explained a concept, ask the chat in Korean. It answers from the transcripts with the passage and minute, so you go back to the right video rather than guessing.
Why online courses stall halfway
You bought the course, and the lectures kept coming faster than you could watch them.
✗ A queue of unwatched videos
Online courses release lectures quickly, and catching up means hours of video at 1.5 times speed. Notes taken while pausing every few minutes miss as much as they catch.
- Dozens of lectures waiting to be watched
- Notes written while pausing the player
- Nothing to search across forty videos
- Examples you remember but cannot find
- Revision that means rewatching
- Services that end the file at one hour
✓ An online course you can search
Each lecture becomes Korean text with a brief and chapters. Together they form the course's notes, written from what the lecturer said, with a timestamp beside every passage.
- About 3 minutes per 90-minute lecture
- The lecturer's name carried into the summary
- Chapters by unit
- Terms and examples collected
- Chat across your transcripts
- TXT or DOCX for revision notes

FAQ
Online lecture recordings, the common questions.
How long does each 인강 lecture take?
About 2 minutes per hour of audio, so a 90-minute lecture takes about 3 minutes. Forty lectures uploaded together are done in a couple of hours at most, usually less.
What does a full 인강 course cost?
Forty 90-minute lectures are 3,600 minutes on the $24 pack of 5,000. Twenty 1-hour lectures fit the $12 pack of 2,000, and five 90-minute lectures fit the $6 pack of 500 minutes.
Can I transcribe lectures from any lecture site?
Only lectures you are allowed to download or record. Check the service's terms; many keep lectures inside their own player. Your own recordings, used with permission for personal study, are the usual case.
How large may a lecture file be?
The limit is 2 GB per upload until you buy a pack, and 5 GB or 10 hours per file after that. A 90-minute lecture video is usually well inside that, and audio is much smaller.
Is Korean the only language?
No. 99 languages are detected automatically, so a lecture in Korean, English, Japanese or Chinese needs no setting. A Korean lecture with English terms is detected as Korean; check technical terms where they matter.
Which formats come back, and who can see the lectures?
Downloads cover TXT, DOCX, SRT, VTT and JSON for any study app. Recordings are transcribed on our own servers and are never used for training, and you can delete each lecture after you have the text.
