Sit in class and soak it in. LectureSync captures every word and turns it into a clean, exam-ready summary, sorted by class. No frantic typing, no notebook full of half-sentences you'll never reread.
On the Mac App Store · The AI never leaves your Mac · Study on iPhone, iPad & Watch
Record class, get back clean notes, and find them sorted and waiting for you. No more piecing together what you missed or borrowing someone else's blurry photos.
In person? Use your mic. Online lecture, recorded talk, or a Zoom call? Capture the audio straight from your Mac. Either way, it's one click.
Everything can happen on your laptop: no internet needed, and none of it gets uploaded to us. Great for spotty campus Wi-Fi, or lectures you'd rather keep to yourself.
Your Mac can do all the transcribing and note-writing itself, at no extra cost. Or connect an AI service you already use (like OpenAI) for an extra boost. Totally up to you.
Your lecture comes back as a clean summary with the key points pulled out: the stuff you'll actually review before the exam, not a wall of text.
Every lecture is saved into its own folder for each class, so your notes stay organized all semester without you lifting a finger.
Equations come out properly formatted, so your calc, chem, and physics notes are actually readable instead of a mess of symbols.
Stuck after class? Ask your lectures questions and get answers that point back to the exact moment, right on your Mac. Then quiz yourself with study cards made from each lecture, every card backed by your professor's exact words. Record a whole semester and still find anything: one search box reaches every transcript, note, and study card.
Recording a live lecture from your mic or screen audio, with a running timer.
Sitting in a lecture hall? Use your mic. Watching a class online? Grab the audio right off your screen. Then put your phone down and just listen. Even a three-hour seminar is no problem.
Last week's Zoom recording, a lecture video, a podcast, even a rough transcript: drag it onto LectureSync and get the same clean notes. Recorded the class on your iPhone or iPad? Drag the memo out of Voice Memos and the audio and its transcript come along together.
Drag a file straight onto your class, or use the Import button.
Real notes from a real lecture: a summary, the key points, and the full transcript.
The moment class ends, LectureSync writes down everything that was said and turns it into a tidy summary with the key points front and center. You also get the full word-for-word transcript, in case you want to go back and check something.
Your finished note, saved in Obsidian and sorted by class.
Your notes don't get stuck inside some app you'll forget about. They save into Obsidian (a free, super-popular notes app) as simple files, sorted into a folder for each class. Search them, highlight them, and study however works for you.
Your Mac's notes and study cards, waiting on your phone and your wrist.
Your Mac still does the work: recording, transcribing, and writing your notes. But now those notes, transcripts, and study cards ride along to your iPhone, iPad, and Apple Watch, so the ten minutes before class actually count.
Your lectures aren't training data for some AI company. LectureSync has no servers and no account: out of the box the recording, transcribing, and note-writing all happen on your Mac, and we never see any of it. Turn on your Mac's built-in option and the AI runs completely offline. Prefer an outside AI service? That's opt-in, with your own key, and only the provider you picked ever sees your text.
Studying on your phone or watch? Your notes and cards sync through your own private iCloud, the same place your photos and messages already live: Apple's, not ours. Nothing is ever sold, and there are no ads or trackers anywhere.
