AI Tutor is a math homework helper and study buddy that never just hands you the answer. Snap a photo of a math problem, and your AI math tutor reads it and asks you step-by-step questions until you solve it yourself, the way a great math tutor does. WHY STUDENTS AND PARENTS CHOOSE IT • Math homework help for grade 1 to grade 12: elementary math, middle school math, high school math, algebra 1, pre-algebra, geometry and word problems • Step by step math, not a math solver: the tutor gives hints, checks your work and asks the next question • Scan math problems with the camera or pick a photo; handwriting and several problems in one picture are fine • Snap your written work: the tutor points to the exact line that went wrong and keeps guiding • Answer by typing, by voice, or by handwriting on the iPad scratchpad • Stuck? Ask for a hint, say "I'm stuck", or get a short lesson that re-explains the concept with a new example • Animated visuals for fractions, geometry, number lines and bar models • Your study buddy Pi, a little dog in a graduation cap, waves, thinks along and celebrates every correct step TOPICS COVERED Fractions, decimals, percent, ratio and proportion, equations, algebra, geometry, area and perimeter, word problems, arithmetic and mental math, functions, statistics and probability, exam prep. FOR PARENTS Help kids with math even if you have forgotten how. Use it as a math checker for finished homework, or let the app sit with your child while you cook. The parent report shows problems done, time spent, how much was solved without help, and the skills that need practice. Share it with one tap. LEARN MATH BETTER The tutor remembers where your child usually trips up and brings it back at the right moment in the next problem. Every session ends with a summary of the concepts used, so learning math sticks instead of copying answers. LANGUAGES English, Vietnamese, French, Chinese, Japanese and Korean. The tutor teaches in the language of the problem. BY GRADE Grade 1, grade 2, grade 3, grade 4, grade 5 (elementary math), grade 6, grade 7, grade 8 (middle school math, pre-algebra), grade 9, grade 10, grade 11, grade 12 (algebra 1, algebra 2, geometry, precalculus). Also used for homeschool math, summer math practice, math test prep and catching up after a missed class. FREE Unlimited problems. No sign-in required to start. Sign in to keep your progress across devices. AI Tutor is the homework app for students who want to actually understand math, and for parents who want more than a photo math answer key.
