Capture
Upload them, paste them, link them — or hit record and catch the lecture live. Papers, slide decks, textbook chapters, YouTube, class itself. A whole semester of a course lands in one notebook, every source transcribed and searchable.
Spaced repetition, source-grounded
Apex turns your lectures, PDFs and slide decks into flashcards, then uses spaced repetition to hand each one back at the moment it's about to slip — every card traceable to the source it came from.
With Apex, four reviews keep recall near 93% on exam day. Reading once without review fades toward zero.
How it works
Lectures, PDFs, slides, diagrams, videos, and late-night notes all belong to the same course. Bring them together in one notebook, and Apex turns the most important ideas into evidence-backed flashcards. Instead of managing a separate deck for every file, you get one focused review queue built from the full picture.
Upload them, paste them, link them — or hit record and catch the lecture live. Papers, slide decks, textbook chapters, YouTube, class itself. A whole semester of a course lands in one notebook, every source transcribed and searchable.
Every source becomes flashcards without the busywork. Apex reads across the notebook, finds what's worth remembering in each one, and drafts the cards — including labeled diagrams, occluded automatically, one label at a time.
Nothing is invented. Every flashcard points back to the exact sentence, page, or timestamp it came from, one click away. AI you can audit, instead of AI you have to take on faith.
Then the real work starts, in one queue that mixes every source you fed it. Spaced repetition learns how you forget, card by card, and brings each one back at the moment it's about to slip — so a semester of material compounds instead of evaporating.
What students use it for
Start recording at the beginning of class and walk out with the transcript already processed and the cards drafted — from what your professor actually emphasised, not what a stranger thought was important. Check your school's recording policy first; the rules vary by institution and by instructor.
PDFs, slide decks, textbook chapters, journal articles, study guides. The handout and the deck your professor actually taught from end up in the same notebook as the recording, so a whole course sits in one place instead of four.
Labeled diagrams are not flattened onto a card as a picture. Apex occludes the labels and quizzes you one at a time — the difference between recognising a diagram and being able to draw it from memory.
Paste a YouTube link and Apex works from the captions. Audio from a review session, or notes you typed yourself, work the same way. One notebook per course, whatever the material arrived as.
Trust
This is the part most AI study tools skip, and it is the reason to care. A general-purpose chatbot asked to make flashcards from a chapter will produce confident, plausible cards — and a fraction of them will be things your professor never said. You find out during the exam.
Every card Apex drafts points back to the exact sentence, page or timestamp it was built from, one click away. If a card looks wrong, you check it in about two seconds. Nothing is invented, and you never have to decide whether to trust it in the abstract.
Why a wrong card is worse than a missing one. Fabricated detail is a documented failure mode of large language models, and a flashcard is the one place you cannot afford it: the whole point is to drill something until you believe it without checking. Source-grounded cards let you use AI for the tedious part without outsourcing your judgement.
From the beta
“I read for fun, and nursing school was the first thing that ever took that away. Making flashcards out of the diagrams was most of it — hours of retyping labels for a single lecture. Apex builds those cards itself now, covering the labels and quizzing me one at a time, and every card still links back to the line it came from. I've got enough evenings back that I'm reading actual books again.”
“The problem with nursing school isn't learning pharm. It's still knowing pharm four months later when you're deep in OB. Apex Memory keeps the old material surfacing while I'm learning the new stuff, so nothing quietly falls off the back of the truck. I do my reviews between pickleball games with George Strait going, and it still sticks.”
Questions
A study tool that turns your own course material — lecture recordings, PDFs, slide decks, YouTube videos — into flashcards, then uses spaced repetition to bring each card back just before you would have forgotten it. Every card links to the exact place it came from.
It builds cards only from the source you gave it, and every card carries a link back to the exact sentence, page or timestamp behind it. That does not make an AI infallible — it makes it checkable. If a card looks wrong, one click puts you on the line it was drawn from, so you settle it in seconds rather than discovering the problem in an exam. Tools that generate cards without citations give you no way to do that.
Reviewing something at increasing intervals — a day, then three days, then a week — timed to land just before you would forget it. Each successful recall makes the memory more durable and buys a longer gap before the next one. It is the most consistently supported finding in the research on long-term retention, and it is why four short reviews beat one long cram.
No. There is no algorithm to choose, no intervals to tune and no vocabulary to learn. You review the cards Apex puts in front of you; the scheduling happens underneath.
Anki's scheduling is excellent and free, but you have to build every card yourself or download someone else's deck — and a downloaded deck cannot tell you where any given card came from. Apex drafts cards from your own material, cites its sources, and schedules without configuration. Anki still wins on price, offline use and its shared-deck library; if you already have an Anki workflow you like, you probably do not need to change it.
PDFs, slide decks, textbook chapters, journal articles, audio recordings, YouTube links, and text you type or paste. You can also record a lecture live inside Apex and have the transcript processed as it goes.
Apex works on whatever you give it, so the material from your own program is exactly what it is for — the closed beta happens to be running with nursing students, and their lectures, chapters and diagrams are nothing special to it. To be clear about what it is not: Apex is not an exam-prep product and ships no question bank of its own. It makes cards from your material, not from someone else's syllabus.
