One recording gets you the whole toolkit. Every word, transcribed and searchable. Study notes built for the exam. Cards that quiz you on what's about to slip. And a tutor that answers from what your professor actually said. All of it on your Mac. No subscription. Nothing uploaded.
Use your mic for an in-person class, or capture the sound playing on your Mac for an online one. While you record, a little red dot with a running timer lives in your menu bar, so you always know it's working, even with the window closed.
Recording in progress: timer, level meter, and your course list.
A lecture only happens once. So LectureSync treats every recording like it's irreplaceable, because it is. Your audio is saved continuously while you record, not at the end.
Recording live is optional. Drag a file (or a whole stack of them) onto a class and LectureSync takes it from there. Even straight out of Apple's Voice Memos.
Watch it happen: a Voice Memo dragged straight onto a class, and the notes start writing themselves.
Every lecture comes back as clean, organized Summary notes. And with the app's built-in models, you can go a step further: a full Study Guide built for exam prep, not just review.
Study Guide works with LectureSync's built-in note-writing models (and oMLX, if you run one). Other setups get the Summary style, and if a lecture's too short for a full guide, the app says so instead of padding it.
Real lecture math, rendered like a textbook, and it looks right at 9am or 2am. Try the switch.
Any lecture can become a deck of study cards: a question on the front, the answer on the back, and under every answer, the exact words from the lecture it came from.
Cards are made with the same note setup you already use, fully on your Mac if that's how you run it. Re-transcribe a lecture later and its deck flags itself, with a one-click rebuild.
A lecture's deck: flip a card and the professor's exact words are right under the answer.
Show in Lecture opens the transcript at the quote, and the play button starts the audio right there.
The wrap-up is honest: what you recalled, and what's worth another look.
Once a class is in, you can ask it questions in plain English and get answers from your own lectures, not the open internet, not a textbook it guessed at.
Ask in plain English; each answer links back to the moment it came from.
Every lecture keeps its complete transcript right alongside its notes, nothing thrown away once the summary is written.
Search the transcript, then click any line to jump the audio right to it.
One search box covers everything you've recorded. Type a word and LectureSync finds it across every lecture, every set of notes, and every study card, in every class.
One box, your whole semester: a click jumps you right to the lecture.
Out of the box, everything (recording, turning speech into text, writing the notes) happens on your computer. No account. No sign-in. No tracking inside the app. Once its models are downloaded, it works with the Wi-Fi off. Cloud AI exists only if you turn it on, with your own key, and your pick of provider, and your key lives in the Mac's own secure Keychain.

Notes land in a folder you choose, as plain files any notes app can open, designed to drop straight into an Obsidian vault, sorted into a folder per class with tidy dated filenames.
The finished note at home in Obsidian, yours to edit, tag, and keep.
No menus to decode on day one. LectureSync checks what Mac you have and recommends the right note-writing setup for it: you see the download size up front, watch the progress bar, and you're done. Setup only finishes when everything's actually ready to record. The first time you open the app, a short walkthrough gets transcription and notes set up and leaves you a sample lecture to look around, so you see real notes before you record your first class.
Choices stay curated: the app surfaces good picks, not a wall of options.
Tags, folders, and a Recent list keep a whole semester of lectures findable, and a lot of it happens on its own while the notes are being written.
The sidebar: course folders, a self-filling smart folder, and Recent, all in reach.
Its own icon and color, its own notes folder, its own settings. Set once, forget forever.
A live badge on each one (recorded, in line, being written up, done), so nothing silently stalls.
Lectures process one by one in the background with a progress bar at the bottom. Reorder the line, cancel something, or just let it run.
A true Mac app: light mode, dark mode, or follow the system. Notes (and their math) adapt too.
Transcript, notes and all: try a different style or model on the copy without touching the original.
Redo the transcript from the saved audio, or take another pass at the notes; every pass is kept as its own version.
Record it, drop it in, or paste the transcript, then walk away with study material that's actually yours.
