Free Audio File to Notes
Knomi Notes turns an audio file into study notes: upload an MP3, M4A, WAV, WebM or OGG recording up to 50 MB and get a summary and structured sections from what was said, in a few minutes. It is free with no paid plan, and the audio is deleted once the note is written.
Add material: upload a file, paste a link, record, or paste text.
How it works
Upload the audio
An MP3, M4A, WAV, WebM, OGG or Opus file up to 50 MB: a voice memo, a recorded class, a study group.
It is transcribed and written up
The words become a transcript, and the transcript becomes notes with a summary on top.
Make it stick
Flashcards, a quiz marked as you go, or questions answered from the recording.
Who it's for
Students with voice memos
Classes recorded on a phone, finally turned into something you can revise from.
Study groups
A group session recorded and written up for everyone who was there.
Language and music students
Spoken explanations and oral practice sessions, kept as text.
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.
Which audio formats work?
MP3, M4A (the iPhone voice memo format), WAV, WebM, OGG and Opus, up to 50 MB per file. Video files are not accepted; for a video on YouTube, paste the link instead.
How long does it take?
Transcription takes a minute or two for a typical lecture, then the notes are written as you watch.
Can I add the slides too?
Yes. Add the slides, a PDF or pasted text to the same note, and Knomi writes one set of notes from the audio and the material together.
How accurate is the transcript?
Clear speech close to the microphone transcribes well. Background noise, several people talking at once, or a phone at the back of a large hall make more mistakes, mostly on names and technical terms.
What happens to my audio?
It is transcribed and then deleted. The transcript text and the note stay in your account and nobody else's.
