Free Lecture Recording to Notes
Knomi Notes records a lecture right in your browser, up to three hours, or takes an audio file you already have, and turns what was said into structured notes with a summary and key terms. It is free with no paid plan, and the recording is deleted once the note is written.
Record the class as it happens. The audio is turned into text, then deleted.
Add material: upload a file, paste a link, record, or paste text.
How it works
Record or upload
Press record when the class starts (up to three hours), or upload an MP3, M4A, WAV, WebM or OGG file up to 50 MB.
Knomi listens and writes
The audio is transcribed, then written up as a summary and sections, with the definitions the lecturer gave set apart.
Study what was said
Flashcards, a quiz or a timed test from the lecture, or ask the note a question about it.
Who it's for
University students
Hour-long lectures where writing everything down means hearing none of it.
Students who need support
Anyone who finds it hard to listen and write at the same time, or who wants to re-read a class later.
High school students
A class, a revision session or a tutor's explanation, kept as notes.
Questions
Is it free?
Knomi Notes is free, with no paid plan and no trial that runs out. You need a free Knomi account to save what you make; you can set everything up before you make one.
How long can a recording be?
A recording made in the browser can run up to three hours. An uploaded file can be up to 50 MB, which is roughly three hours of a browser recording; a high-quality file from a phone runs out sooner.
Does it work on a phone?
Yes, in the phone's browser. Keep the screen on and the tab open while it records. You can also record with your phone's voice memo app and upload the file afterwards.
What languages does it understand?
The transcription detects the language spoken. It is strongest in English; other widely spoken languages work, with more mistakes on technical terms.
Should I ask before recording a lecture?
Yes. Many schools and lecturers have rules about recording, so check your course's policy or ask the lecturer first.
What happens to the recording?
The audio is transcribed, written into your note, and then deleted. Only the note and the transcript text stay, in your account.
