MITORU is a learning support app where AI instantly and automatically grades calculation answers written by students on paper drills or handouts, simply by taking a picture with a device's camera and uploading it. It supports calculation problems, including the four basic arithmetic operations for elementary school students. It significantly reduces the burden of daily manual grading that teachers and parents have conventionally performed, while also strongly supporting the establishment of an "independent learning cycle" where students notice their own mistakes and proactively rework them. [Specific Steps for Use] The specific steps are as follows: The student works on calculation problems on a paper drill or handout.Using the device's camera, they take a picture of the completed handout.When the captured photo is uploaded to MITORU, high-precision grading by AI begins immediately.They check the grading results. For any incorrect problems, they erase them with an eraser, solve them again, and repeat the process of taking a picture, uploading, and grading.Once all answers are correct, they submit it to the teacher.In this way, it is a learning support tool that allows students themselves to utilize AI for grading, a task traditionally done by teachers or parents.
