Not every card is worth your time. Sekel knows which ones are.
The flashcard app that actually knows your exam. Sekel pairs FSRS spaced repetition with official exam blueprints — USMLE, NBME shelves, NCLEX, and more — so the cards that move the needle for your exam show up first. Not another Anki clone.
Your IM shelf is in 14 days. You're struggling with Cardiology (62% accuracy) — weighted 15–20% on the blueprint. These 38 cards are your highest-leverage study right now.
A 58-year-old man presents with chest pain, diaphoresis, and ST elevation in leads II, III, aVF. Most likely diagnosis?
Inferior STEMI — RCA occlusion. Check right-sided leads (V4R) for RV infarct. Avoid nitrates if RV involvement suspected.
Most flashcard apps treat every card the same.
Sekel doesn't.
Whether you're studying for Step 1, an NBME shelf, or NCLEX-RN, you're drowning in cards and short on time. Sekel was built from scratch — not as another Anki skin — to fix the gap traditional flashcard apps were never designed to close.
Exam blindness
Anki treats every card equally. Your boards don't. Cardiology is 30% of Step 1. Pharmacology is 13% of NCLEX-RN. Your deck doesn't know that — Sekel does.
Content overload
Med, nursing, and shelf students all face the same problem: hundreds of new cards every week. Without prioritization you grind low-yield content while high-yield topics slip.
No urgency signal
Six weeks out vs. six months out should feel completely different. Traditional spaced repetition has no concept of your exam date. Sekel builds its whole session queue around it.

Exam-aware studying in three steps.
You don't need to change how you study. Sekel adds the exam context that traditional flashcard apps were never designed to have — for medical students, nursing students, and anyone preparing for a high-stakes board exam.
Register your exam
Tell Sekel which exam you're studying for and when it is — Step 1, an NBME shelf, NCLEX-RN, or any of our supported boards. Sekel loads the official blueprint and uses it to score every card you own.
Study as normal
Review cards using the FSRS algorithm — the most accurate spaced repetition scheduler available. Every rating you give builds a picture of your real weak areas, on your exam.
Sekel prioritizes for you
Before each session, Sekel combines your performance data, the blueprint weightings, and time-to-exam to surface the highest-leverage cards first. You always know why a card is being shown.
The same card. Different exam. Different priority.
A Cardiology card is high-yield for the IM shelf, also high-yield for Step 2 CK, but only medium-yield on NCLEX-RN. Sekel adjusts dynamically based on the exam you registered — pulled from official outlines, not third-party guesses.
Yield is calculated from official exam blueprints published by USMLE, NBME, and NCSBN. Not guesses, not scraped, not third-party.
Triage mode locks to 2.5× — max-urgency cards only.
Built for the way clinicians
actually study.
Not a re-skinned Anki. Sekel ships with the things you used to need add-ons for — plus the exam intelligence Anki was never built to have.
Turn First Aid, Saunders, or any PDF into flashcards.
Drop in a PDF, lecture slides, or a YouTube link. Sekel reads it, extracts the key concepts, and generates cards. Med school textbooks, nursing review books, shelf prep — any source you already use. Cards land in your Drafts inbox first. You approve each one before it hits your deck.
Draw a box. Make a card.
Anatomy diagrams, histology slides, ECG strips, lab value charts, nursing pharmacology infographics — upload any image and draw shapes over the structures you need to learn. Each shape becomes its own card, with multiple study modes for guessing one or revealing in sequence.
A daily card target that scales with your exam.
Enter your exam date. Sekel calculates how many cards to study each day, ramping as the exam approaches. It also flags coverage gaps — systems that are underweighted in your deck relative to the official blueprint. No more spreadsheets.
Built on official blueprints — for whichever exam you're taking.
Sekel ingests content outlines directly from the governing bodies that publish them — USMLE/NBME for medical students, NCSBN for nursing students. When they update, Sekel updates. New exams ship as we add them.
