⚠️ This is the 4th edition — your course assigns the 5th
Your graded work lives in the 5th edition on Oxford Insight, inside Canvas, and the syllabus restricts the course to that version. This copy is the 4th edition (2021, ISBN 9780197542811) — same 15 chapters in the same order, so it is genuinely useful for reading and review, but page numbers differ and some content was revised for the 5th. Read here; submit there. Do not cite a page number from this copy.

How the tutor works
Chapter or whole book
Ask within the open chapter, or switch to Whole book and the server searches all 16 chapters and returns the best passages.
Names its sources
Each answer reports how many passages it used and which chapters they came from, so you can check it against the page.
Keyless by default
Runs on Cloudflare Workers AI at no cost to you. Add your own Gemini or Claude key only if you want a stronger model. Confirm your course's AI policy before using it on graded work.
Says "not in this chapter"
If the chapter doesn't cover it, the tutor is told to say so rather than guess.
