Record the lecture, search it before the exam

Stop choosing between listening and writing. Murmur records the lecture and turns it into a timestamped transcript you can search, replay sentence by sentence, and export as study notes.

Notes taken at speaking speed are notes with holes in them

You either follow the argument or you write it down. A recording alone does not fix it — nobody re-listens to a 90-minute lecture to find one definition.

Searchable, not just recorded
Type the term and jump to the second the lecturer defined it, with the match highlighted in place.
Read along with the audio
The transcript scrolls in sync while it plays, so revision is reading, not scrubbing.
Tap one line, hear one line
Replay a single sentence as many times as it takes — no fiddling with a scrubber.
Notes you can hand in or hand over
Export as Plain text, Markdown, PDF, Word, or pass the transcript to an AI assistant to generate a summary or flashcards.
