When grading tests and homework, even if you redo the problems they got wrong immediately, children often make the same mistakes again after a while. It's frustrating that the corrections aren't being retained—a common feeling for many families.

Manabi Notebook is a parent-child learning notebook designed to transform your child's "mistakes" into "successes."

■ There are only three steps:

① Capture… Take a picture of the problem they got wrong. You can also register test corrections all at once.

② Appear… The app automatically presents the problem when they're starting to forget.

③ Master… Tap "Mastered" when they've solved it. Repeating this process helps solidify the learning.

No complicated input is required. Just take a picture. It also supports optical character recognition (OCR), making it easy to review later.

■ Why does it "stick"?

People forget what they've learned over time. However, encountering the material again just as it's starting to fade significantly strengthens the memory—this is a scientifically proven learning method.

Manabi Note automatically adjusts the interval between subsequent questions based on your child's "accomplished/almost there/still needed" status. Problems they understand well are presented with longer intervals, while those they're unsure of are repeated. The app automatically creates the most efficient review schedule, so parents don't have to worry about "what to review today."


■ Effort is visible.

Children are much more motivated when they see their "accomplishments" increase together than when you simply say, "Study!" Manabi Note displays the growth in the number of mastered problems in a graph. You can see your child's progress at a glance.

Furthermore, it automatically analyzes which units your child is struggling with. It visualizes difficult units in a ranking, making it clear "what should be focused on now." Make the most of the time and money you spend on cram schools and correspondence courses.

■ For families like these:

・Even though we correct mistakes after every test, we're worried about whether the knowledge is truly retained.

・We want to steadily overcome weaknesses instead of leaving them unaddressed.

・We want to improve the quality of home study in preparation for junior high school entrance exams and regular tests.

・We want to create a sustainable habit for both parent and child.

■ You can use it with peace of mind.

・Registered problems are saved on your device. Automatic backup to the cloud is available when you log in. Peace of mind even when changing devices.

・No ads are displayed. The screen remains focused on studying.

・Data is encrypted during transmission and storage. Privacy is prioritized.
