Kartesio: AI Math Solver

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 get more. No account, no sign-up, no subscription. 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.
