The tutor supports questions about a lesson. It gives no grades, changes no academic status and identifies itself as AI before the first answer.
It never grades
Grades, pass decisions and academic progression remain entirely outside the tutor. That separation is built into the product, not left to a policy.
Labelled from the first message
Students are told they are talking to a machine before the first answer, as Article 50 requires — not in a footnote.
Anchored in your lesson
It quotes the material of the lesson it sits under. That material sits in a separate, bounded block and is declared a source to quote — never something to obey.
Your provider, your key
Natively ChatGPT or one of eight remote cloud providers — plus your own OpenAI-compatible cloud endpoint. The school provides the key, so the provider contract, usage and bill stay with the school.
Outside the lesson, it says: not in the material
When a question falls outside the lesson material, it says so instead of inventing a plausible paragraph.
Bounded by design
Daily and per-minute limits, write-only key storage, no way to redirect it at another endpoint.
