Essay marking

Marked the way a real marker reads.

Not one score. Three levels — mechanics, craft, and meaning — twenty-one checks, paragraph by paragraph. Every mark is a question that teaches, and a teacher signs off before the student sees it.

A Memory Frozen in TimeYear 8 · student draft
Marked · 21 checks

Some memories stay in your mind forever, like they are trapped in ice. I still remmember it very clear. I was seven, and my hands was sweaty on the metal handles becuase I had crashed before. My dad stood behind me, holding the back of the seat. “You’re ready now” he said. I did not feel ready at all — I felt scared and nervous and afraid.

My stomach twisted like a potato in a washing machine. I could hear birds yelling in the trees and a dog barking far away. My knees was shaking badly. I wanted to say no but the word got stuck in my throte.

The three-level read

Mechanics, craft, and meaning.

A marker reads the same paragraph several times over — once for each level. MarsLadder runs twenty-one checks across the three, and every one is a question, not a correction.

Spelling, grammar and punctuation — the surface a marker corrects first.

The rubric

The rubric is yours. The AI just drafts it.

Upload the task and the AI drafts a rubric — the criteria and their weights — from what the piece is meant to do. You review it, adjust it, approve it. The essay is marked against that, not a generic scale.

① TEACHER
Uploads the writing task
The prompt, the year level, and what the piece is meant to do.
② AI
Drafts a rubric — criteria & weights
Built from the task itself, not a generic scale — each criterion with its own weight.
③ TEACHERYOU OWN THE STANDARD
Reviews, adjusts & approves it
Change a weight, reword a criterion, cut one — the rubric is only final when you say so.
…and every mark is reviewed by the teacher before the student ever sees it.

The mark is the start of the rewrite.

Every flag is a question that points the way. The student rewrites the weak lines and resubmits — and the score climbs, draft after draft, because the writing itself got better.
