AI Study Notes and Revision From Your Lecture Recordings

Yes. Upload the recording and you get a timestamped transcript with speaker labels in a few minutes — a one-hour lecture typically takes about two. Transcription works without an account for files up to 50 MB.

Yes. Upload the MP4 or audio-only file Zoom exports. Teams and Google Meet recordings work the same way, as does anything you download from Panopto, Canvas, Moodle, or Blackboard — over 30 audio and video formats are supported.

Yes. The summary covers the topic, the key points, and the conclusions, and further one-click passes pull out key quotes, action points, and deadlines mentioned in the lecture. Summaries need a free account; the transcript itself does not.

Yes, in two ways. Inside a lecture you can search the transcript and click any line to hear that moment. Across your account, one search box finds which lectures mention a term — useful when you remember a concept but not which week it was covered.

Up to 99% on a clear recording. A lecturer with a lapel microphone recorded through the conferencing tool transcribes very well; a phone at the back of a hall does not. Distance from the speaker matters more than anything else, so record close to the source if you can.

Yes. Speaker labels separate the lecturer from students asking questions, which matters in seminars and tutorials where the discussion is the point. Accuracy drops when people talk over each other or when a question is asked far from the microphone.

Yes. 90+ languages are detected automatically, and supported transcripts can be translated from the editor in your account — useful if you are studying in a language you are still learning. Translation needs an account.

PDF and DOCX are paid exports, along with SRT and VTT. On the free tier you can export TXT and JSON and download the original audio, which is enough to move your notes into a document or a notes app.

A one-hour lecture usually processes in about two minutes. Longer recordings take proportionally longer, and processing time also depends on the audio quality and how busy the queue is.

Yes, and these are often the recordings worth transcribing most. In a seminar the useful material is the discussion, which is exactly what is hardest to reconstruct from memory a month later.

Yes. Upload the M4A, MP3, or WAV your recorder app produces. If you recorded a lecture on a phone in your bag, expect lower accuracy — the microphone is the limit, not the transcription.

Yes, for any recorded class. One thing to check first: universities differ on whether students may record lectures, and some require the lecturer’s permission or an accessibility arrangement. That policy is between you and your institution.

That is what most students use it for. Read the summary of each lecture, work out which classes you are shaky on, then search for the concepts you cannot recall and jump to the minute they were explained. What it will not do is predict what is on the exam.

Yes, if you have the recording as a file. Course videos you have downloaded transcribe the same as any other recording. Note that many course platforms do not allow downloading, and their terms are yours to check.

Free uploads are capped at 50 MB per file, roughly an hour of compressed audio — enough for most single lectures. Longer recordings and large video files need a paid plan.
