Use cases / Exam tutor

Exam tutors

Self-funded candidates with a sitting date, a revision pack they already buy from you, and questions at eleven at night. We turn your worked examples into lessons they can drill on a phone, and answer their questions from your pages while you sleep.

What we build for you

Your worked examples, live

A curve with the inputs on sliders, a case that branches, a check with a reason under every answer.

A tutor that quotes you

It answers from your pages only and cites the passage. If they're silent, it's built to say so. Learners can ask you too.

Exam week handled

Learners' questions become edits you approve once. Refunds, receipts and lost passwords come to us.

Whole example lessons in your field

Built from public sources to show the shapes. Yours would be drafted from your material.
