About this app

Do you really know the math concepts?

Check your understanding with free True/False, Calculation, and Basic problems, and ask questions via photos if you get stuck.

Wonri AI achieved a Grade 1 in all CSATs from the 2021 to 2026 academic years and recorded an accuracy rate of over 95% on more than 20,000 commercially available problems.

You can ask questions about multiple problems at once, and pinpoint specific parts of the solution you don't understand to ask again.

Results may vary depending on the difficulty of the actual question and the quality of the photo.

■ AI Problem Solving via Photo

Upload a photo of a problem you don't understand, and Wonri AI will explain the solution. You can ask questions about multiple problems at once. If a photo contains multiple problems, select the area for each problem to check the solution for each.

You can pinpoint specific parts of the solution you don't understand to ask again, and you can also ask about math concepts in writing.

■ Concept Summary with Detailed Illustrations and Explanations

From Middle School 1st Year to High School 3rd Year, examine the meanings and properties of concepts, as well as conditions that are easy to confuse. You can also review concepts you need while solving problems.

** ■ From Concept Check to Basic Problems

Check concepts with True/False questions and apply them directly through calculations and basic problems. You can view the correct answer and explanation for each question.

The types of problems provided vary depending on the learning content of the sub-unit. True/False, calculation, and basic problems are available for free.
