The chemistry student struggle
“Organic chemistry has hundreds of reactions. I need to know them all for the final.”
— Pre-med sophomore
“My professor's handwritten mechanisms are hard to read, let alone study from.”
— Chemistry major
“I spend more time making flashcards than actually learning the material.”
— Biochem student
Built for chemistry
Reaction Recognition
Photo handwritten reactions and mechanisms. AI identifies reagents, products, and conditions.
Mechanism Quizzes
Get questions on electron movement, intermediates, and product prediction. Not just 'name this reaction.'
Functional Group Review
AI identifies functional groups in your notes and creates targeted identification questions.
Nomenclature Practice
IUPAC naming conventions are tedious to memorize. Quiz yourself until they stick.
When to use Cruxly
Before Lab
Review procedures and safety protocols. Know what you're doing before you do it.
Orgo Exam Review
Photo your reaction summary sheet. Quiz yourself on mechanisms and products.
Gen Chem Concepts
Turn lecture notes on equilibrium, thermodynamics, or kinetics into practice questions.
Biochem Pathways
Metabolic pathways have many steps. Photo them and quiz the intermediates.
Frequently asked questions
Can it handle organic chemistry mechanisms?
Yes. Our OCR recognizes arrow pushing, curved arrows, and common structural drawings. Complex multi-step mechanisms may need minor review.
What about chemical structures?
We can read most hand-drawn structures including rings, functional groups, and stereochemistry indicators. Very detailed 3D representations may be simplified.
Does it understand chemical equations?
Yes. Balanced equations, reaction conditions, and stoichiometry problems are handled well.
Is it useful for lab courses?
Definitely. Photo your lab manual or pre-lab notes to create quizzes on procedures, expected results, and safety protocols.
Reactions down. Mechanisms memorized.
Spend less time making flashcards. More time understanding chemistry.
