Turn a lecture recording into study guides, checked against your material
Upload a lecture recording and QuerySpark writes study guides from what is actually in it, so you can see the whole topic on one page on exactly what your course covers. MP3, M4A, WAV, MP4, WEBM and more, up to 25 MB.

How we read lecture recordings
We transcribe the audio with Whisper, which also pulls the audio track out of video files, then write questions from the transcript so you can study a lecture you only half heard.
Get the best results
- Record in mono at a modest bitrate; speech does not need music quality.
- Pair the recording with the slides for the richest set.
What your study guides include
- A structured outline of the main topics in your material
- Key terms, learning objectives and common misconceptions
- Worked examples where your material has them
- Practice questions at the end of each section
How you study them
Read the guide to get the shape of the topic, then jump into practice from any section. The guide and the questions come from the same analysis, so they cover the same ground.
Best for: starting a new unit, condensing a long reading, the night before an exam.
Things that trip people up with lecture recordings
- Recordings over 25 MB need splitting or compressing first (a 60 minute lecture in mono MP3 at 48 kbps fits).
- Lecture-hall echo and distance from the speaker reduce accuracy. Sit near the front or use a clip-on mic.
- Apple .mov files are not accepted. Convert to .mp4 or export the audio.
