MateIA: Math Tutor with AI

MateIA is your AI math tutor: solve any problem step by step, check your photographed exams, and practice for free without limits. Step-by-step solutions are NEVER locked behind a subscription: no accounts, no card, no surprises.

🧮 SOLVE ANY PROBLEM STEP BY STEP, FREE
Type or photograph a problem (word problems too) and MateIA explains every step and the why, not just the answer. You confirm the photo before sending: it never "solves the wrong problem".

✅ VERIFIED SOLUTIONS
When possible, MateIA checks the AI's solution with its own math engine and tells you honestly: "Locally verified".

📝 CHECK YOUR EXAM OR HOMEWORK
Photograph your sheet and get per-question feedback on what went wrong. Nobody else does this.

♾️ UNLIMITED FREE PRACTICE IN ALL 23 TOPICS
Infinite exercises with full step-by-step across the whole curriculum: arithmetic, fractions, percentages, linear and quadratic equations, systems, polynomials, inequalities, progressions, probability, functions, trigonometry, analytic geometry, derivatives, integrals, complex numbers and statistics. From primary school to pre-university.

🔥 DAILY CHALLENGE AND STREAKS

🔓 NO TRICKS, NO SUBSCRIPTION, EVER
Unlike other math apps, the full step-by-step is NEVER behind a paywall or a "free trial" that needs a card. MateIA is 100% free with ads: AI use is paid by watching a short ad, with the price visible before you tap.

MateIA is a study aid. AI answers may contain mistakes: always double-check with your teacher or official material.
