パシャレク－算数・数学の宿題をAIが解説

This is a math support app for elementary and junior high school students, brought to you by Dainippon Tosho, publisher of textbooks approved by the Ministry of Education, Culture, Sports, Science and Technology.

Simply take a picture of a problem you're stuck on in your homework or drills with your smartphone or tablet. AI will explain the solution step-by-step using slides and audio.

This app is not for copying answers. It prioritizes understanding "why" things work the way they do.

■ Recommended for families like these:

・"I want to help, but I don't know how to solve it."

・"To ask the cram school, I have to wait until the next class."

・"My child is doing homework late into the night and doesn't have the energy to read explanations."

・Both parents work and have little time to help their children with their studies.

■ How to use in 3 steps

1. Take a picture of the problem you don't understand with your camera.

2. Crop the necessary parts and send.

3. AI will create a slide and audio explanation.

Then, simply follow along with the audio by flipping through the slides.


■ Main Features

【Automatic AI Explanation Generation】
The AI ​​reads the captured problem and automatically creates a slide-style explanation and audio guide. Instead of immediately showing the answer, it's structured to deepen understanding step-by-step, starting with hints on how to think through the problem.

【AI Chat】
If you don't understand something after reading the explanation, you can ask questions directly via chat. The explanation will be in simple language, tailored to your child's level of understanding.

【Furigana Display】
Furigana (phonetic readings) can be displayed for kanji characters. Three modes are available: "Elementary School (all kanji)," "Junior High School (difficult kanji only)," and "Adult (no furigana)," allowing even younger children to read independently.

【Similar Problems】
Similar problems related to the problems solved will be presented. This can be used for review to avoid repeating the same mistakes.

【Learning History】
All explanations created so far are recorded. This can be used for review before tests.

【Mini-Lessons During Waiting】
You can keep practicing with mini-lessons while explanations are being created.
