AI Sensei Info I: CT Code

AI Sensei Info I is a programming learning app specialized for preparing for the Common Test "Information I" in university entrance exams. You can efficiently learn the pseudocode (DNCL / Common Test program notation) that has become essential in the new curriculum for the Common Test, all while feeling like you're playing a game.

▼ Recommended for
・High school students currently studying "Information I"
・Exam takers aiming for the Common Test 2026 and 2027
・Programming beginners who want to learn the basics of Python and pseudocode
・Those who want to review repeatedly and overcome weaknesses during their free time
・Those who want to score well in information subjects, regardless of their academic stream (humanities or sciences)

▼ Assemble code by "tapping" instead of typing
No keyboard input is required. You can assemble the Common Test pseudocode (DNCL / DNCL2 standard code) by simply tapping components. You won't get stuck on syntax errors, allowing you to focus on the algorithmic concepts themselves (conditional branching, loops, arrays, functions).

▼ See code execution step by step
When you run the code you've created, changes in variable and array values are visualized step by step. The trace function allows you to visually follow and understand "why that answer is obtained." You can also use it for practicing past questions in the same format as the actual Common Test.

▼ AI Tutor guides your "thinking process"
When you don't understand, ask the AI Tutor. Instead of giving you the complete answer, it provides hints and guides your thinking process to promote metacognition. Based on Gemini 2.5, it provides answers tailored to the question trends of the Common Test "Information I".

▼ Learning design that keeps you going like a game
・Level up by clearing stages in quests
・Collect over 32 types of badges
・National rankings (12 indicators in total, including XP, correct answer rate, consecutive days, etc.)
・Form a habit with consecutive learning days
・Train your quick thinking with time attacks

▼ Wide range of questions
In addition to programming (191 questions, DNCL2 compatible), it also includes knowledge questions on information society, information communication networks, and data analysis (over 400 questions in total). Incorrect questions are automatically added to a review list, making it easy to overcome weaknesses.

▼ AI Tutor (3 free uses/day, unlimited for premium members)
・Ask the AI a question for each problem
・Freely consult for "hints," "alternative solutions," "meaning of expressions," etc.
・Explanation history is saved for each problem (premium members)

▼ Multi-language support (Japanese / English / Simplified Chinese)
Supports not only Japanese examinees but also international students and overseas residents studying information subjects. All in-app menus, AI Tutor, and even the glossary are available in three languages.

▼ Learning history on device + cloud
Nicknames and statistics are saved to the cloud for ranking purposes. We do not collect names, emails, addresses, etc. Ads use AdMob and are ATT compliant.

▼ Usable in these situations
・Want to solve just one question on the train commute or during a break
・Focus on reviewing weak areas (programming, data analysis)
・Want to understand pseudocode from past questions by tracing its execution
・Want to understand the essence of algorithms, not just memorize
・Want to compete with friends and classmates in rankings

Let's conquer the Common Test "Information I" in a fun and essential way, like a game.
