Which AI answers your questions?

The AI tutor is Claude Opus 5.5 (Anthropic), a large language model made by Anthropic, called through the official Anthropic API (model id claude-opus-5-5).

• It answers in English, Sinhala or Tamil — whichever language you chose — but always keeps Civil 3D commands in English (e.g. CreateSurface).
• It receives the lesson you are viewing, your stage and your earlier questions on that lesson, so its answers fit where you are in the course.
• It can explain again more simply, give new worked examples, and quiz you one question at a time.
• Your questions and its answers are saved in your history in this site's SQLite database.
• Like any AI, it can make mistakes. If something does not match what you see in Civil 3D, trust the software and ask again.
