01
Add your lecture
Drag in a recorded lecture — MP4, MOV, WebM, MKV, MP3, or M4A. The file is read locally; nothing is uploaded yet.
Recorded lecture → notes
Lecture notes from video, ready to study from.
For students and lifelong learners who would rather review clean notes than rewatch the whole class.
Get lecture notes from video automatically: drop a recorded lecture and get a full transcript plus study notes — a summary, the key points and definitions, and a timeline — that you can download as Markdown or plain text. The audio is extracted in your browser and only the audio is sent for transcription; the original lecture video never leaves your device.
- Study summary
- Key points and definitions.
- Lecture to text
- Full searchable transcript.

- Only audio is sent, never the video.
How it works
Three steps from a lecture to study notes.
02
Transcribe and summarize
We extract the audio in your browser, transcribe the lecture to text, then use AI to turn it into a study summary, the key points and definitions, and a timeline.
03
Review, copy, or download
Read the study notes on the page, copy them into your notes app, or download the notes as Markdown and the full lecture transcript as a text file.
Why use it
Study the lecture, not the playback bar.
Get a study summary and key points instead of pausing and rewinding to scribble notes.
Use the timeline to jump straight back to the topic you need before an exam.
Keep the lecture transcript and notes as files you own to revise from anytime.
More note types
Notes for meetings, podcasts, and any video.
Recording something other than a class? Turn a call into meeting notes from video, condense an episode into a podcast summary, or make general notes from any video. Only need the sound? Extract the audio as MP3, M4A, or WAV.

Lecture notes questions
How do I turn a lecture into notes?
Drop a recorded lecture onto the box at the top of this page or choose a file. The audio is extracted in your browser and transcribed, then AI writes study notes — a summary, the key points and definitions, and a timeline — that you can read on the page or download as Markdown or plain text.
Is my lecture recording uploaded to a server?
The original video stays in your browser. We extract a small compressed audio track locally and send only that audio to generate the transcript and lecture notes — the original lecture video file is never uploaded.
What do the lecture notes include?
You get the full lecture transcript plus study notes: a summary of what was covered, the key points and definitions, and a timeline so you can jump back to a topic to review it. Download the notes as Markdown (.md) and the transcript as plain text (.txt), or copy them into your study doc.
Can I get notes from a long lecture or a YouTube lecture?
The website handles a lecture of up to 10 minutes per run and accepts common recordings — MP4, MOV, WebM, MKV, plus audio files like MP3 and M4A. For a full-length class or a YouTube lecture, use the Chrome extension, which turns longer videos and YouTube links into notes right in your browser.
Is it free and is there a usage limit?
It is free with no sign-up. There is a small daily limit per device on making notes from a lecture to keep the service available for every student.
