Stoichiometry and reactions
Balancing equations, mole relationships, limiting reagents, yields, and tracking units through a calculation.
Chemistry tutoring
A Socratic AI chemistry tutor for reactions and calculations
Chemistry problems mix symbols, quantities, structures, and physical explanations. Stemio keeps those representations together and guides you toward the connection that unlocks the next step.

What you can practice
Chemistry work that stays connected to the reasoning
Write equations, units, electron movement, structures, and calculations on the same whiteboard. Stemio can respond to how the chemical idea and the mathematics fit together.
Equilibrium and acids–bases
Equilibrium expressions, shifts, buffers, titrations, and deciding which approximations are justified.
Thermochemistry and kinetics
Energy changes, spontaneity, rate laws, mechanisms, and connecting graphs with molecular explanations.
Structure and bonding
Lewis structures, molecular geometry, intermolecular forces, orbitals, and structure–property reasoning.
Guided problem solving
How a chemistry session works
Add the chemical equation, structure, or data and show the approach you would try first.
Stemio checks conservation, units, assumptions, and chemical meaning before nudging the next step.
Your corrections stay connected to the underlying topic, which can later appear in your study plan.
Problems you can bring
Start with the line where you are unsure
- Finding the limiting reagent without losing the mole ratio
- Deciding whether an equilibrium approximation is valid
- Using molecular geometry to explain a physical property
Your level, your language
Guidance calibrated to the course you are taking
Stemio adjusts from introductory chemistry language to the notation and depth used in university and graduate work, while still introducing unfamiliar techniques when needed.
You can also choose your tutor language, so an unfamiliar term does not have to become an extra obstacle.
Common questions
About Stemio for chemistry
Can Stemio read chemical equations?
Yes. It can read equations and calculations from the whiteboard, and chemistry notation is rendered clearly in the tutor conversation.
Can it help with conceptual chemistry questions?
Yes. The tutor can focus on particle-level explanations, trends, assumptions, and structure–property relationships as well as numerical work.
Will it balance a reaction for me?
It will guide you to inspect atoms, charge, or half-reactions and help locate an error, while leaving the balancing work to you.
