Faster marking, still your judgement
- A suggested mark for each question, criterion or strand
- The evidence from the student’s work behind each suggestion
- Feedback drafted for the student, ready to edit
- Every grade confirmed by you

How it works
Three steps
- 1
Students submit
Work comes in online, or on paper through scanned answer sheets.
- 2
Thoth suggests
It reads each answer against the rubric, suggests a mark with its reasoning, and drafts feedback.
- 3
You decide
Accept, adjust or overrule each suggestion. Only what you confirm becomes the grade.
What you get
What comes out the other end
Marks against the rubric
For MYP, a level from 0 to 8 per criterion or sub-strand. For PYP, against the strands. Points for other courses.
Evidence shown
Each suggestion points to what in the student’s work it was based on.
Feedback drafted
Written comments for each student that you can edit before they see them.
Final grade suggestions
Across a set of work, xedu suggests final grades in your class’s own grading scheme.
Language Acquisition phases
MYP Language Acquisition work is judged against the right phase.
You stay in control
Suggestions are never released automatically. A teacher confirms every grade.
Any curriculum
Works with the course you teach
Criterion-based marking is built for IB MYP (criteria A–D, sub-strands, 0–8 levels) and PYP (subject strands). For DP, IGCSE, British, A-level, American and AP classes, work is marked in points today, and you apply your own grade boundaries.

Questions
Common questions
Does the AI grade on its own?
No. Thoth suggests marks and feedback, and a teacher confirms every one before it becomes a grade.
How does it know what a good answer looks like?
It marks against the rubric attached to the assignment, which you can review and edit, and shows the evidence it used for each mark.
Can it mark handwritten work?
Yes, when students write on the QR-coded answer sheets xedu prints. See paper test marking.
