Convert Lectures to Notes in 3 Steps
Upload Your Lecture Recording
Drag and drop your lecture file (MP3, MP4, WAV, M4A, OGG, WebM, or MOV) up to 4 hours long. Select the audio language from 51 supported options or let auto-detect handle English, Mandarin, and Cantonese. Works with phone recordings, Zoom captures, and in-room audio.

Select from 4 note formats: Cornell Method (two-column with summary), Hierarchical Outline (Roman numerals and letters), Bullet Points (flat list with sub-bullets), or Table Format (terms with definitions and examples). Pick a study preset like Exam Prep Notes (adds review questions and glossary) or Concept Map Notes. Set your subject area from 8 disciplines and toggle emphasis markers for [EXAM], [DEF], [!], and [EX] tags.
Download Your Structured Notes
Musely transcribes and synthesizes the lecture using map-reduce processing, then delivers structured notes with bolded key terms, formatted definitions (Term -- definition), and indented examples.

Who Uses Musely Lecture to Notes Converter
Focus on listening instead of scrambling to take notes
I used to split attention between listening and scribbling notes and missed half the lecture. Now I record every class, upload to Musely, and get Cornell-format notes with definitions already bolded. My GPA went from 3.2 to 3.7 the semester I started using this.
Capture clinical terms and procedural steps accurately
Musely's Medicine subject preset preserves clinical terminology exactly and the Detailed detail level catches procedural nuances I would have missed. The Exam Prep preset generates review questions that match the Step 1 style. I saved roughly 6 hours per week on manual note-taking.
Get notes in Mandarin from English lectures
My professors lecture in English but I process concepts faster in Mandarin. Musely transcribes the English audio and outputs notes in Chinese with technical terms preserved in English in parentheses. Bilingual mode lets me cross-reference when I need to study for English-language exams.
Prepare supplementary materials from recorded lectures
I TA three sections and need to build study guides that match the professor's exact points. Musely's Quick Summary preset condenses a 2-hour lecture into 8-12 essential bullets in under 5 minutes. My students consistently rate my supplementary guides higher than the professor's slides.
Build a searchable notes library from Coursera and edX
I take 3-4 MOOCs at a time across Coursera, edX, and YouTube. Musely converts every lecture into Markdown notes that import cleanly into Obsidian. The Concept Map preset shows how ideas connect across courses. My personal knowledge base finally feels unified instead of scattered across 40 playlists.
Extract actionable takeaways from webinars and CEUs
I attend 10+ hours of professional development webinars per month for my CE credits. Musely's emphasis markers tag [EXAM] and [!] content so I can review during my commute instead of rewatching full recordings. I passed my recertification exam on the first attempt after years of struggling.

What Students Say
4.9/5 based on 3,214 reviews
“My GPA jumped from 3.2 to 3.7 the semester I started using Musely for my bio and chem lectures. The Cornell Method output with definitions already bolded replaced 4 hours of manual note rewriting per week. The Exam Prep preset review questions matched my actual midterm almost exactly.”
“The Medicine subject preset preserves clinical terminology that generic transcription tools mangle. I process 3-hour lectures in one pass and the Detailed detail level catches procedural nuances. Musely saved me roughly 6 hours of manual note-taking per week during my clinical rotations.”
“I am an international student and my professors lecture in English. Bilingual mode gives me Chinese notes with English technical terms preserved in parentheses. I can study in my native language without losing the vocabulary I need for English exams. Game-changer is the wrong word but it actually changed my study habits.”
