Recognizing it
isn’t knowing it.
The exam finds out what you actually know. Scholar Stack finds out first — then fixes it: a memory engine, quizzes that rewrite themselves around what you got wrong, and an oral exam that grades what you say. And if you want more, an optional AI voice tutor that already knows where you’re weak.
You can recognize every term on the page and still not be able to say why.
Recognition feels like knowledge until someone asks. Scholar Stack doesn’t just check whether you got a concept right or wrong. It statistically deconstructs your understanding by comparing how you do on multiple-choice questions against how you do when asked to explain the same material out loud, open-ended. Where the two disagree is where the gap is — and every gap becomes a target.
You see “Frank–Starling” on a multiple-choice option and pick it.
Feels like knowing. Isn’t.
Asked out loud, you say why more preload makes the heart contract harder — in your own words.
Knowing it cold.
One recording in.
Proof you know it, out.
Every stage produces something the next stage uses. By the end, the app knows what you can explain, what you only recognize, and what to do about it.
- Capture
One recording
Record the lecture. Your iPhone transcribes the hour in about ninety seconds, offline. Or drop in the files you already have — the app sorts them.
produces a proofread transcript - Structure
The material, organized
An outline of what the professor actually said, and a flashcard deck sized to the lecture.
produces outline · deck - Practice
Adaptive quizzes
Each concept tested from different angles, scenarios and situations — never the same question twice. Every wrong answer changes the next quiz.
produces evidence, per concept - Prove it
Out loud
Say the answer. The oral exam grades what you said, not what you recognized.
produces spoken evidence - Understand
Student Intelligence
Multiple-choice performance is compared against your ability to explain the same material out loud. Where the two disagree is a gap — named, per concept, across the course.
produces your gaps, named - Remember
The memory engine
For the concepts you keep missing: mnemonics on a dial from textbook-dry to impossible-to-forget — as a picture, or as a song.
produces hooks that hold
Want a tutor as well? 
is our separate one-on-one AI tutoring app: it can take your profile and work through the gaps with a custom curriculum, voice to voice. Optional, sold separately, never required.

Board exams don’t ask what you highlighted. They ask what you can produce, under pressure, with nothing in front of you.
This study system was designed by a physician who has been through the testing — years of it. He knows what relentless studying looks like and feels like: the lecture you can’t afford to miss, the stack of material that never gets smaller, the exam that decides what you get to do next. He knows the high-stakes pressure of a career that is graded, and what it is to compete not only with everyone else in the room, but with yourself — the version of you that knew it yesterday and can’t say it today.
That is why the system is shaped the way it is. Quizzes that refuse to repeat themselves, because he watched people memorize the question instead of the concept. An oral exam that demands the explanation out loud, because that is the only test that ever told him the truth. A memory engine, because at some point there are more facts than there is time. And, for those who want one, an optional AI tutor that already knows where you’re weak, because the hardest part of studying alone is knowing what to study next.
It exists because the tool he needed didn’t.
The founder — physician, and the app’s first userYour lectures are nobody’s business.
Most transcription apps upload your audio to someone else’s servers. We rebuilt ours to run on the phone in your pocket.
Transcribed on the device
Speech recognition runs on your iPhone’s neural engine. The words are extracted right there, in the room where they were spoken.
Measured, not promised
A 63-minute lecture transcribes in about 90 seconds on an iPhone 12 — and it works in a lecture hall basement with zero bars.
Honest fallback
On-device transcription needs an iPhone 12 or newer. Older phones and Android use our encrypted cloud pipeline instead — clearly labeled, never silent.
Study-guide and quiz generation use secured cloud AI on the transcript text. Audio backup to your own library is optional.
Engineered to be
impossible to forget.
Some concepts refuse to stick politely. Memory Boost turns the load-bearing facts of every lecture into memory hooks — classic mnemonics, vivid scenes, and memeonics, our meme-format memory aids for the internet-raised brain. It’s all built on distinctiveness encoding: the well-documented finding that the brain files the bizarre ahead of the boring. You choose how far the dial goes.
Clinical
Dry, professional, textbook-grade. The mnemonics your professor would approve of.
Standard
Traditional memory aids with subtle analogies.
Playful
Light humor and funny visualizations. Safe for any classroom.
Memorable
Absurd imagery, unexpected collisions of ideas. Distinctiveness does the encoding.
Unforgettable
The med-school tradition. Clever, suggestive, never explicit — and impossible to unremember.
About Level 5
Medical students have passed boards on scandalous mnemonics for a century — because taboo is the strongest adhesive memory has. Level 5 productizes the tradition, with rules: clever and suggestive at most, never graphic, never explicit.
It unlocks once, behind a real gate: Face ID confirms your device, then a one-time selfie is checked by AI to confirm you’re 18 or older. The photo is analyzed and discarded — never stored — and anything ambiguous is automatically declined. All that’s kept is a yes.
Meet
Real-time conversational AI tutoring sessions and probative AI oral examinations — you talk, it talks back, on the web. Not a human tutor: an AI that never tires and never forgets your gaps. A separate product with its own minute-based plans; Fusion works fully without it, and nothing here is required. Fusion knows what you can’t yet explain; Dynamic is where you go to fix it.
Tutor me
An AI tutor that listens, explains, and pushes back — working from your own lectures, not a textbook. Built to handle math tutoring in advanced concepts, not only reading-based subjects.
Examine me
A probative oral exam that keeps asking until it finds what you can’t explain in your own words — follow-up after follow-up, no hints.

Asked and answered
What can I feed it?
Live recordings, audio files (MP3, M4A, AAC), pasted text, camera scans of handwritten notes, and documents. Whatever form your course material takes, it becomes the same study system.
Is my audio really private?
On iPhone 12 and newer, transcription runs entirely on the device — the audio is processed on your phone. Study-guide and quiz generation then work from the transcript text over an encrypted connection. Cloud audio backup is optional.
How does the oral exam work?
A question appears on screen. You speak your answer, the app transcribes it, and the AI grades the substance against your actual lecture material — with specific feedback on what you missed. It is the closest thing to a professor who never gets tired of asking.
Is there a web version?
Yes. The web console lets you review lectures, transcripts, and study tools from any computer. In the app, go to Profile → Study on Web to create your login credentials, then sign in from the Log in button on this site.
How accurate is the transcription?
Very good on clear lecture audio, in both the on-device and cloud pipelines — and a proofreading pass catches phonetic slips (the app knows your professor said “Krebs cycle,” not “crabs cycle”). Transcripts stay fully editable.
What exactly is Memory Boost Level 5?
The age-gated top setting of the mnemonic engine — clever, absurd, suggestive-at-most memory hooks in the long med-school tradition, with hard rules against anything explicit or graphic. Unlocking it requires Face ID plus a one-time selfie that AI checks for 18+; the photo is analyzed and discarded, never stored, and ambiguous results are automatically declined.
What is Scholar Stack Dynamic?
The spoken half of Scholar Stack: real-time conversational AI tutoring sessions and probative AI oral examinations — you talk, it talks back, on the web. It is an AI, not a human tutor — including math tutoring in advanced concepts. From any course in Fusion, tap Talk this through and Dynamic opens already knowing your gaps and your next exam. Billed separately, by minutes of live session time.
Which devices are supported?
Scholar Stack is built for iPhone, with on-device transcription on iPhone 12 or newer and cloud transcription on older models. The web console works in any modern browser. Android is under consideration.
