Lecture halls with bad reception are fine — transcription is fully offline.
Record the Lecture. Keep the Notes.
Stop choosing between listening and writing. VoiceMaster records your lectures with live on-device transcription — bookmark the important moments, search everything later, and walk out with notes already written.
How to Turn Lectures into Notes
Three steps, about a minute, zero uploads.
Hit record and watch text appear live as the professor speaks. The app keeps recording even while the model warms up.
When something sounds exam-worthy, drop a bookmark with a quick note — one tap, eyes stay up.
Search across all your lecture transcripts, replay any segment by tapping it, and export notes for study guides.
Why VoiceMaster
Private on-device transcription with pro-grade output.
Find “that thing the professor said” across your whole semester in seconds.
120 free transcription minutes every month, no account or card required.
Variable-speed playback with a waveform player — skim the lecture, not the whole recording.
Why Typing Notes in Class Doesn’t Work
Note-taking forces a bad trade: write and you stop listening; listen and you capture nothing. Research on learning keeps showing that divided attention produces worse notes and worse understanding. Recording with live transcription removes the trade — your full attention stays on the lecture while the text takes care of itself.
The bookmark feature is the active part of this workflow. When the professor says “this will be on the exam”, one tap marks the moment with your own note. Engagement stays high, but the capture becomes automatic.
Studying from Transcripts
A semester of transcribed lectures is a personal textbook written in your professor’s own words — and it’s searchable. Preparing for an exam stops being “re-listen to fourteen hours of audio” and becomes “search every mention of the Krebs cycle, then replay just those segments”.
VoiceMaster’s segment-tap playback and variable speed make verification fast: skim the text, hear the original phrasing in one tap, export the passages you need into your study guide as Markdown or plain text. And because everything runs offline, none of it depends on lecture-hall Wi-Fi.
Frequently Asked Questions
Can I transcribe lectures for free?
Yes. VoiceMaster gives you 120 free transcription minutes per month — enough for a couple of full lectures — with no account required.
Does recording work in airplane mode?
Yes. Recording and transcription both run entirely on your device, so airplane mode or dead-zone lecture halls are no problem.
Can I transcribe recordings I already made?
Yes — import existing audio files (m4a, mp3, wav and more) and VoiceMaster transcribes them with the same offline model.
