About this prototype

The problem

MYP students know the content but lose marks turning it into answers. Mark schemes assume an examiner's eye, and general AI tools explain well but don't mark.

What this prototype does

• Exam mode: one bullet per mark, each a cited marking point.
• Evaluation mode: your answer marked point by point, with what's missing and the mistake type.
• Explanation mode: an analogy, plain bullets, a diagram and an exam link.
• Retrieval runs in the browser: 12 chunks retrieved, re-ranked to 6. "How this answer was built" shows it.

What it leaves out

The PRD's model (GPT-5 Mini) is replaced by answers assembled from retrieved marking points. Questions are sample material, not real IB papers. No accounts, study plans or flashcards.

PRD test set (Appendix E)

Runs the ten test cases through the real pipeline.

Upload a mark scheme

The question becomes one chunk and each marking point becomes its own chunk. It stays in this browser only.

Format: a line starting Question:, then one marking point per line.
