The STEM student struggle
“I can solve problems but forget the formulas by exam day.”
— Engineering junior
“My physics notes are full of diagrams I can't type into Quizlet.”
— Physics major
“I need to memorize theorems and their conditions—flashcards help but making them takes forever.”
— Math student
Built for math and science
Formula Recognition
Photograph handwritten equations. Our OCR handles mathematical notation, Greek letters, and subscripts.
Concept-Based Questions
AI creates questions that test understanding, not just memorization. 'What happens to pressure when volume decreases?'
Step-by-Step Explanations
Wrong answers include worked solutions. Understand where you made the mistake.
Unit Conversion Quizzes
Physics often trips up on units. Practice dimensional analysis with generated problems.
When to use Cruxly
Before Problem Sets
Quiz yourself on relevant formulas before diving into homework problems.
Exam Review
Photo your formula sheet. Generate practice questions for each section.
Concept Check
Turn lecture examples into quiz questions to test your understanding.
Lab Prep
Review physics principles before lab sessions with targeted quizzes.
Frequently asked questions
Can it handle complex equations?
Yes. Our OCR recognizes most mathematical notation including integrals, summations, matrices, and Greek letters. Very complex LaTeX-style equations may need minor corrections.
Does it create calculation problems?
Cruxly creates conceptual questions and simple calculations. For heavy computation practice, use your textbook problem sets alongside Cruxly for concept review.
What about diagrams and graphs?
We extract text and labels from diagrams. Pure graphical content (like circuit diagrams) is described but not fully converted—yet.
Is it useful for proof-based math?
Somewhat. Cruxly can quiz you on theorem statements and conditions, but writing proofs requires different practice.
