NCLEX Prep

Pass the NCLEX
Never Forget What You Studied

The AI memory layer for nursing students

Butterfly works alongside UWorld, Kaplan, and ATI to make sure you remember every concept you study — from pharmacology to clinical judgment.

The Problem

The NCLEX Retention Problem

Most nursing students don't fail the NCLEX because they didn't study hard enough. They fail because they forgot what they studied.

3,000+
Concepts to Master
Pharmacology, pathophysiology, clinical judgment, lab values, procedures, and more.
~14%
First-Time Fail Rate
Thousands of nursing graduates fail the NCLEX each year — not from lack of studying, but from forgetting.
2–3 mo
Average Study Period
Concepts studied in week one are fading by exam day without systematic review.

The problem isn't studying harder. It's retaining what you've already studied.

How It Works

Four Steps to NCLEX Confidence

Butterfly adds a retention layer to your existing study workflow. No extra apps to juggle, no flashcards to make.

01
01

Study

Use UWorld, Kaplan, ATI, or watch Mark Klimek lectures as you normally would. Nothing changes about your study routine.

02
02

Capture

Butterfly runs invisibly in the background, capturing the nursing concepts, drug names, lab values, and clinical scenarios you encounter.

03
03

Retain

AI builds your personal nursing knowledge graph, predicts when you'll forget each concept, and schedules targeted reviews before it fades.

04
04

Pass

Walk into the NCLEX with every concept locked in long-term memory. No cramming, no guessing, no gaps.

Integrations

Works With Your Existing Prep Tools

Butterfly doesn't replace your NCLEX prep tools — it makes sure you remember what they teach you.

U
UWorld

Captures rationales from practice questions. When you review a UWorld explanation, Butterfly extracts the underlying concepts and schedules them for retention.

K
Kaplan

Tracks concepts from decision trees and question banks. Kaplan's structured approach pairs perfectly with Butterfly's knowledge graph.

A
ATI

Builds your knowledge graph from content mastery assessments and TEAS prep. Butterfly identifies gaps ATI reveals and reinforces them.

A
Archer

Captures rapid-fire review concepts. Archer's speed meets Butterfly's long-term memory — the concepts stick instead of slipping away.

MK
Mark Klimek

Extracts key concepts from lecture recordings. Butterfly captures the mnemonics, prioritization rules, and clinical pearls as you listen.

Built for Nursing

Every NCLEX Domain, Covered

Butterfly's AI adapts to the specific demands of nursing education — from pharmacology to clinical decision-making.

Rx

Pharmacology Retention

Spaced repetition for drug classes, side effects, interactions, and contraindications. The system predicts when you'll forget Metoprolol's side effects and reviews them before you do.

Dx

Clinical Judgment

Knowledge graph connects symptoms to diagnoses to interventions. Build the mental models NCLEX tests — not just isolated facts, but how concepts relate.

P

Priority & Delegation

Adaptive quizzes focus on your weak areas in the nursing process. If you struggle with delegation rules, Butterfly drills them until they're automatic.

Lab

Lab Values & Vitals

SMS reminders with quick-recall questions on critical lab ranges. Get a text asking 'Normal potassium range?' before the concept fades.

Path

Pathophysiology

AI chat answers your questions grounded in what you've actually studied. Ask 'How does CHF progress?' and get an answer that builds on your existing knowledge.

SATA

SATA Mastery

Adaptive difficulty calibrates to Select All That Apply question types. The system learns where you over-select or under-select and adjusts accordingly.

The biggest risk in NCLEX prep isn't studying the wrong material — it's forgetting the right material. Butterfly eliminates that risk entirely.

The Difference

Traditional Study vs. Butterfly

Same study material, completely different outcome.

X
Traditional NCLEX Study
Re-read, cram, hope for the best
Re-read notes and hope they stick
Passive review creates an illusion of knowledge. You recognize the material but can't recall it under pressure.
No way to know what you've forgotten
You don't realize a concept has faded until you see it on the exam. By then, it's too late.
Cramming the week before
Last-minute cramming creates short-term memory that evaporates within days. NCLEX tests long-term retention.
Manual flashcard creation
Hours spent making Anki cards is time not spent actually learning. And most students quit after a week.
B
NCLEX + Butterfly
Capture, predict, retain, pass
Automatic capture from any source
Butterfly captures concepts from UWorld, Kaplan, lectures, and textbooks without any manual input.
Predicted forgetting with targeted review
AI models your memory for each concept individually. You review exactly what you're about to forget.
Consistent retention over months
Spaced repetition spreads review across your entire study period. Concepts studied in week one are still fresh on exam day.
AI-generated practice questions
Adaptive quizzes generated from your own study material. No card creation — just learning.
