Assessor: privacy-first bulk AI marking

Bulk marking that tells you when it can't mark. Each criterion comes back as marked, not demonstrated, or not assessable. About $0.53 a class.

The flow, end to end

Rubric in, names removed, marked against the rubric, marksheet out. The teacher owns the totals; the model never totals.

Loading a marking rubric into Assessor

3 · De-identify
Assessor declaring what it can and cannot judge
4 · Markability
Marking each piece against the rubric
5 · Marking
A live-formula marksheet the teacher owns
6 · Marksheet

  • About $0.53 to mark a class of 30 essays.
  • Unmarkable criteria come back amber with “Tool couldn’t mark this. You mark it.” The total is flagged incomplete so nobody copies a partial mark.
  • Names are removed before marking. If that step fails, nothing is sent.

Each criterion comes back as marked, not demonstrated, or not assessable. It never guesses a mark to fill a cell.
