Lecture recordings to transcripts
Upload a lecture or talk and get a punctuated transcript; click any line to hear that moment.
Record the lecture, review it without replaying the whole thing
Upload a lecture, seminar or talk as audio or video and Azhu writes a punctuated transcript. Find the part you want to review and click it to play from there.
For reviewing
Click any passage to play from that moment instead of scrubbing through the audio.
An AI summary lists the key points. It's written in a meeting format (key points, decisions, action items), so for a lecture the key points are what matter.
Export a TXT file and paste it into your own notes.
Long lectures
The maximum length of one recording depends on your plan; subscriptions allow longer recordings. See the pricing page. For anything longer, split it into parts with a recording app first.
Once it's uploaded you can close the page and come back when it's done.
Getting a clear recording
- Sit near the front, or put the phone close to the speaker.
- In rooms with a sound system, near a speaker works too.
- Chatter and rustling nearby can drown out the speaker, so pick a quiet spot.
- On a phone, turn on Do Not Disturb so a call doesn't interrupt the recording.
Ask first
Ask the teacher or speaker before you record. Many courses and events have their own rules about recording, and transcripts are for your own study, not for sharing publicly.

What if the lecture is in Hokkien or English?
That works. Choose English for English lectures, or “Taiwanese Hokkien” for Hokkien, which is written out as Mandarin.
What about technical terms?
List the course's terms before uploading and the transcript and summary follow your spelling. You can also fix anything as you listen.
Does it work on a phone?
Yes. Upload from your phone's browser and read the result there too.
