About this app
Kartesio solves maths exercises step by step. Photograph a problem from your
textbook or notebook, or type it in, and get the full working — not just the
answer.
WHAT IT SOLVES
• Arithmetic — fractions, decimals, percentages, powers, roots
• Algebra — linear and quadratic equations, systems, inequalities
• Polynomials — factoring, expanding, remarkable products, division
• Functions — domain, zeros, sign, intercepts, graphs
• Trigonometry — sine, cosine, tangent, goniometric equations and inequalities
• Logarithms and exponentials
• Limits — including indeterminate forms and asymptotes
• Derivatives — rules, chain rule, tangent lines
• Integrals — indefinite and definite, integration by parts and substitution
• Analytic geometry — points, lines, distances, areas
• Euclidean geometry — triangles, polygons, circles, angles
• Statistics — mean, charts, data representation
HOW IT WORKS
Point the camera at the exercise and crop just the part you need. Kartesio
reads handwriting too, shows you what it recognised so you can correct it,
then walks through the solution one step at a time — with the rule that
justifies each step.
Every graph is drawn for you: the shaded area under an integral, the tangent
line of a derivative, asymptotes, the number line for an inequality, a pie
for a fraction.
CHECK YOUR OWN WORK
Already solved the exercise? Photograph it and Kartesio finds the mistake,
names the rule you missed, and suggests how to verify the result yourself.
BUILT-IN VERIFICATION
Where the mathematics allows it, the answer is checked by a computer algebra
system — not just produced by AI. Verified results carry a badge, so you know
what has been double-checked.
ADAPTS TO YOUR LEVEL
Set your school level once and explanations follow: the balance model for
middle school, formal principles for high school, straight to the point at
university. A harder exercise gets solved regardless of the setting.
MATHS KEYBOARD
Type exercises directly with a proper mathematical keyboard: fractions,
powers, roots, integrals, limits, Greek letters and set notation.
HISTORY AND SHARING
Solved exercises stay on your device and can be reopened any time. Share a
complete solution — steps and graph included — as an image.
FREE, WITH ADS
Kartesio is free. Scans are limited each day; watch a short rewarded ad to

A NOTE ON ACCURACY
Kartesio is a study tool. Explanations are generated by an AI model and
verified where possible, but mistakes are possible: read the steps, and never
submit an answer you do not understand.
