Cathedra records your lectures and turns them into text, so you can stop writing things down and actually listen.
RECORD WITHOUT THINKING ABOUT IT
Add your timetable once: Cathedra reminds you before each class, with recording one tap away on the Lock Screen. Lock the phone and leave it on the desk — recording carries on, and pauses for the break.
READ IT BACK AFTERWARDS
Every recording becomes a timestamped transcript. Tap any line to hear exactly what was said, at up to double speed. The original audio is always kept: the transcript is a convenience, the recording is the record.
FIND ANYTHING, ACROSS EVERY LECTURE
Search the full text of every lecture you have recorded and see every moment a term came up — including every time a lecturer said "this is in the exam".
ASK YOUR LECTURES ANYTHING
With Cathedra AI, ask about one lecture or a whole course — "what did the lecturer say would be on the exam?" — and get an answer from what was actually said, with the moment it was said. Ask it to put the exam in your calendar or find the lecture where a topic came up, and it does; every change can be undone.
THE WHOLE LECTURE ON ONE PAGE
Every lecture can become a summary: an overview, the key points with the moment each was made, the terms and what to revise. Turn the terms into flashcards, or quiz yourself on what was said.
BUILT FOR ANY UNIVERSITY
Semesters, trimesters, quarters, blocks, Dutch periodes or one continuous year: pick the shape your university uses and set the dates. Import your timetable from a calendar on your iPhone, or type it in.
EXAMS AND DEADLINES ON THE SAME CALENDAR
Your classes and exams in one month view, with the exams and deadlines a lecturer announces added for you. Cancel a class and its reminder goes with it; schedule a make-up for a new time.
MORE THAN 40 LANGUAGES
Set the language your lecturer speaks, per course. Your iPhone's own speech recognition covers more than forty; with Pro and Max, lectures are transcribed on Cathedra's server instead, which saves battery. The app itself is in 22 languages.
ON EVERY DEVICE
Sign in with just your email — no password — and your library lives in your Cathedra account, the same on every iPhone you sign in on and at cathedra.study. Without an account, everything but Cathedra AI works and stays on your iPhone.
YOUR LECTURES ARE YOURS
Without an account, your lectures never leave your iPhone. Signed in, your courses, timetable, transcripts, notes and questions are kept in your account on our servers. With a Cathedra AI subscription your recordings and photos are kept there too, and with Pro and Max lectures are transcribed there; Settings switches both off. When you use Cathedra AI, what it needs — the text, or a question you dictate — goes through our server to the AI service. No advertising, no tracking, no third-party code. Usage statistics say nothing about who you are, and Settings switches them off.
WORTH KNOWING BEFORE YOU RECORD
Recording a lecture captures someone else's voice, and local law and your university's rules decide whether you may. Please check them, and never publish a recording of someone who did not agree to it.
CATHEDRA AI
Recording, transcription, search, the timetable, and summaries and flashcards made on your iPhone are free. Cathedra AI — asking your lectures, adding exams to your calendar, quizzes, reading a lecture in your language, photographs of the board explained — needs an account and is an optional Pro or Max subscription, monthly or yearly; Max adds practice exams and study plans. It renews automatically until you cancel in your Apple Account settings.
