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
For students and lifelong learners who would rather review clean notes than rewatch the whole class.
Convert a lecture video to a notes summary automatically: drop a recorded lecture — MP4, MOV, WebM, or MKV — and AI notes from the video are written for you: a full transcript plus study notes with a summary, the key points and definitions, and a timeline you can download as Markdown or plain text. Works for a short or long video, and the audio is extracted in your browser; only the audio is sent for transcription, so the original lecture video never leaves your device. To transcribe a YouTube lecture, use the Chrome extension.
How it works
01
Drag in a recorded lecture — MP4, MOV, WebM, MKV, MP3, or M4A. The file is read locally; nothing is uploaded yet.
02
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
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
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.
The website transcribes an uploaded lecture video clip into a notes summary; for a longer class or a YouTube lecture, the Chrome extension turns the video into notes.
More note types
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.
Make notes from any videoFAQ
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, key terms with short definitions, and a timeline — that you can read on the page or download as Markdown or plain text.
Yes. Before you start you can set the spoken language of the recording and the language you want the notes in, separately — both default to auto-detect. So an English lecture can produce notes in your own language, while the transcript stays in the language that was actually spoken.
The full lecture transcript plus study notes: a summary of what was covered, the key points, a list of key terms with short definitions — useful when a lecture introduces a lot of new vocabulary — 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).
Transcription quality follows the audio. If a recording is quiet, echoey, or heavily accented, setting the spoken language yourself instead of leaving it on auto-detect usually helps, because the model no longer has to guess which language it is hearing. Very noisy recordings will still produce mistakes — the full transcript is there so you can check anything that matters.
A single upload can be up to an hour, and the site covers about an hour of audio per device in total. For a full-length class, a whole lecture series, or a YouTube lecture, the Chrome extension transcribes longer videos and YouTube links right in your browser.
