Aidona Launches STORY5 LEARNING LINK for Civil Engineering Exam Prep
The service is built around the exam's shift from memorization to applied understanding, and the AI is designed to withhold direct answers to push that shift.

Aidona Inc. began offering STORY5 LEARNING LINK on September 1, 2026, a study service for the first-class civil engineering construction management engineer first exam. It runs entirely inside LINE: a 20-minute video lecture per theme, four-choice mock tests, a stage-based review game, and an AI chatbot that answers questions in text and voice. The chatbot draws on a 1,500-term glossary and the user's own test results, and it refuses to give direct answers.
Aidona built the service around a change in the exam itself. The first exam now requires two passing bars at once: an overall score and a 60 percent or higher on the applied ability section, so memorizing past questions no longer reaches the pass line. Reiwa 8 added new question themes to that section, and the company designed the lectures, tests, and games so each theme can be swapped out as the exam shifts.
The AI chatbot sits at the center. It answers questions in plain text and reads the answer aloud, using a voice dictionary tuned for civil engineering terms such as "kuugeki" for void and "jiyama" for natural ground. It also reads the user's own test history, so it can name the three weakest themes and point to the matching lecture.
The bot will not state a correct answer. It gives reasons and hints and steers the user to the relevant explanation, a deliberate choice because the exam now tests understanding rather than memorization.
- 20-minute video lectures: diagram and narration covering key points and the reason behind each answer
- Four-choice mock tests: same format as the real exam, including count and combination questions
- Review game: stage-based quiz with combo scoring that lets users finish all stages
- AI chatbot: answers questions in text and voice, drawing on a 1,500-term glossary and the user's scores
