Kairyudo Publishing Launches AI-Powered English Teaching Tool for Middle Schools

Revolutionizing English Education with kAIryu-kun



Kairyudo Publishing, based in the Bunkyo ward of Tokyo, has recently launched an innovative AI application called "kAIryu-kun," designed to assist middle school English teachers by automatically generating educational materials. This tool leverages data from Kairyudo's own Sunshine English textbooks, addressing significant challenges in the current educational environment where generative AI is becoming more prevalent.

The Need for Streamlined Teaching Resources


In recent years, educational institutions have been exploring the possibilities of integrating generative AI into their teaching practices. However, generic AI models often present problems, such as including unlearned vocabulary in generated exercises and the complex nature of creating effective prompts. Responding to these concerns, Kairyudo's kAIryu-kun simplifies the process of developing custom tests and reading materials in line with students' learning progress.

Key Features of kAIryu-kun


The application comes equipped with three core functionalities designed to meet the specific needs of educators:

1. Intuitive User Interface in Easy Mode
- Teachers can create materials with just a few clicks, eliminating the need for complicated prompts. Users can select the grade level, unit, and problem format to produce various educational resources quickly.

2. High-Quality Output with Systematic Checks
- The AI is trained on Kairyudo’s copyrighted textbook data, allowing for the creation of materials that are tailored to the grammar and vocabulary levels appropriate for students. While the system aims to prevent the inclusion of unlearned content, teachers will conduct the final checks and adjustments, ensuring high-quality resources while saving substantial preparation time.

3. Seamless Output to Common Software
- Generated content can be directly copied and pasted into popular software like Microsoft Word and Excel, facilitating immediate printing in a properly formatted layout, thus allowing educators to integrate this tool into their existing workflows.

Affordable Subscription Plans


To facilitate easy adoption within educational budgets, Kairyudo offers a flat-rate subscription model for schools, allowing unlimited access for all teaching staff at a low annual fee. Options range from one to three-year plans, each providing a set number of monthly usage credits for tests and reading materials.

Comprehensive Support and Free Trial


Kairyudo Publishing also recognizes the importance of providing sufficient support for educators adopting new technology. They've launched a dedicated support site that offers manuals, FAQs, and email assistance from specialists. Additionally, through their official LINE account, users receive ongoing updates on practical usage examples and new features.

For those interested in trying out the service, Kairyudo provides a free trial version for educational professionals to assess its effectiveness firsthand.

Commitment to Data Security and User Guidelines


Kairyudo is committed to ensuring the security of users' data. Input data is saved solely for quality improvement and analysis, with strict policies prohibiting any personally identifiable information from being entered into the system. Furthermore, the service usage is limited to designated teachers from contract-approved institutions, ensuring that materials are exclusively tailored to their students’ needs.
