Chalkdust: AI Lecture Notes
Record class, get flashcards
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Record a lecture, walk out with notes, flashcards and a quiz, then ask your whole course anything. Transcribed on your iPhone. Your audio never leaves it.
Record the lecture. Walk out with notes.
Chalkdust turns every class into study material you'll actually use: structured notes, flashcards and a practice quiz, with the deadlines and exam dates your professor mentioned pulled out for you.
LIVE TRANSCRIPT
Words appear as your professor speaks, transcribed entirely on your iPhone. Tap any line later to hear that moment again, at whatever speed you like.
NOTES THAT READ LIKE NOTES
Organized by topic, key terms in bold, definitions kept in your professor's own words, and anything they said would be on the exam called out.
ASK YOUR WHOLE COURSE
"What did she say would be on the exam?" Ask anything about your lectures and get an answer drawn only from what was actually said, with a link to the exact moment in the recording. The search runs on your iPhone; only the few relevant passages are used to write the answer.
SEE WHO SAID WHAT
The transcript marks when a student asks a question and when the professor answers, so Q&A is easy to find later.
FLASHCARDS AND QUIZZES
Made from every lecture. Flashcards use spaced repetition, so you review each card right before you'd forget it. Quizzes check what you actually understood.
MARK WHAT MATTERS
Tap once when you hear "this will be on the midterm." Your marks get extra weight in the notes.
NEVER MISS A DEADLINE
Readings, problem sets and exam dates mentioned out loud are collected at the top of your notes.
PRIVATE BY DESIGN
Your recordings never leave your iPhone. To write notes, Chalkdust sends only the transcript's text, and keeps nothing afterwards. No account to create.
TRY IT IN TEN SECONDS
Open the built-in sample lecture to see notes, flashcards, a quiz and Ask before you record a thing.
PRICING
Recording and transcripts are free, always, and notes for 3 lectures a month are free too. Chalkdust Pro covers every lecture: $2.99 a month, or $19.99 a year with a one-week free trial. Subscriptions renew automatically until cancelled; manage them in Settings.
Before you record: many schools require the instructor's permission. Please check your school's policy.
