Lecture transcription

To transcribe a lecture, upload the recording, choose the language, and read the timestamped transcript. Use the search to find a topic and the timestamps to jump to that moment in the audio. One file up to 15 minutes and 25 MB is free with no account. Export TXT or Markdown for your notes.

Record the lecture, drop in the file, and get a transcript with timestamps. Search it for a term, jump to the moment in the recording, and build your notes from text instead of re-listening to the whole hour.

Free preview: one file up to 15 minutes and 25 MB, 3 tries a day, no account needed.

Key facts

Check you may record first

Many universities and teachers allow recording for personal study and some do not. Ask before you record, and keep the transcript for your own use unless you have permission to share it.

Getting a recording that transcribes well

  • Put the phone or recorder near the speaker, not at the back of the room: distance and echo cost more accuracy than anything else.
  • Record the question-and-answer part too, but expect audience questions from far away to be the roughest lines.
  • Technical terms and names may be misspelt. Read the transcript with your slides open and fix those first.

Studying from the transcript

Every line carries a timestamp, so a search for a term in your transcript tells you where in the recording it was said. Edit the lines you are unsure of while you listen back, then export as plain text or Markdown for your notes, or as a CSV with one row per segment if you want to sort and annotate it.

A long lecture needs an account

The no-account preview covers one file of up to 15 minutes. A ninety-minute lecture is longer than that, so create a free account for longer files or split the recording into parts. Transcripts in an account are kept in a library you can search across.

How it works

  1. Add a recording

    Drop in a video or audio file, choose one from your device, or record from the microphone. Nothing to install.

  2. It transcribes

    Speech becomes timestamped text, with speaker labels when more than one person talks.

  3. Read, fix, export

    Click any line to correct it, then download TXT, subtitles, Markdown, JSON or CSV.

Questions

Can I transcribe a recorded Zoom or Teams lecture?
Yes. Download the recording file from your platform and upload it; only the audio track is used.
Will it tell the lecturer apart from students?
Speaker labels separate different voices (up to eight) when more than one person talks. Rename them once you know who is who.
Is the transcript a perfect record?
No. It is a draft: check names, numbers, formulae spoken aloud and anything you will be examined on against the audio.
Is it free?
Yes — one recording up to 15 minutes and 25 MB with no account, up to 3 tries a day. A free account keeps your transcripts in a library and lifts the guest limits; the current limits and paid plans are on the pricing page.
Do I need permission to record a lecture?
Ask the lecturer or follow your institution's policy before recording.
How do I get good lecture audio?
Sit near the front or use a phone close to the speaker, and avoid recording through a laptop mic across a room.
Can I turn the transcript into study notes?
Export Markdown or TXT and edit it. Summarising is up to you.
Can it handle long lectures?
Up to 15 minutes per file without an account; longer with one.
Does it work for lectures in other languages?
Yes, 33 languages plus automatic detection.
