A lecture note taking app helps you get spoken material into organized, searchable text. Luma does this with voice capture: speak into the microphone (with permission to record), get an AI-cleaned transcript as an editable note, then organize it, summarize it, or turn it into flashcards. It's a single-speaker voice tool, not a multi-speaker meeting transcriber.
Capture lectures by voice, clean up the transcript with AI, and turn the result into notes you can actually study from.
Recording a lecture involves someone else's voice, not just your own. Check your school's or course's recording policy and ask your instructor before recording. Some institutions restrict or prohibit lecture recording, and consent laws around recording other people vary by location. Luma doesn't manage permissions for you — that responsibility is yours.
Luma's voice capture is designed around one microphone picking up one primary voice at a time. In a lecture hall, that means it will transcribe what it can hear clearly, but it won't distinguish the lecturer from student questions across the room, and it won't produce speaker labels the way a dedicated meeting-transcription tool does. Background noise, distance from the speaker, and overlapping talk all reduce transcript quality — this is a limitation of single-microphone speech recognition generally, not specific to Luma.
Students who take notes during lectures and want a faster way to capture what's said, review it, and study from it — see our broader guide to note-taking for students. If you'd rather type than record, the same organization, search, and study tools apply to typed notes through our AI note-taking app.

Luma's voice capture is built for recording your own voice — speaking notes, summaries, or recaps into your phone or laptop microphone — and turning that speech into a cleaned-up text note. It works for recording a lecture the same way any single-microphone voice memo does: it captures what the microphone picks up and transcribes it, but it doesn't label multiple speakers or separate the lecturer's voice from ambient classroom noise.
Often, yes. Many schools and instructors have specific policies about recording lectures, and some jurisdictions have consent laws that apply regardless of institutional policy. Always check your school's recording policy and ask your instructor before recording a class, and never record without appropriate permission.
It depends heavily on microphone placement, room acoustics, and background noise. A phone sitting on a desk in a large lecture hall will produce a noisier transcript than a quiet room with a nearby speaker. We don't publish an accuracy percentage because it varies this much by conditions.
The transcription becomes a normal, editable note in your notebook. From there you can tag it, search it later, generate an AI summary to review the key points, or generate flashcards to study the material before an exam.
Yes. You can type notes during the lecture and separately capture voice notes (like a quick spoken recap right after class), and keep both in the same notebook or note, tagged so you can find them together later.
Transcript cleanup after voice capture and any AI summary or flashcard generation each count toward the free plan's 5 AI actions per day. Typing and organizing notes doesn't. Premium ($2.99/month or $24.99/year) removes the daily AI action cap.
