The grading loop, without the backlog

Ruberis is modeled on how writing teachers already grade. The AI’s job is to save you time — not to make decisions you don’t get to see.

How Ruberis works

Four steps. Roughly the same workflow you already use — just with the tedious part automated.

  1. 01

    Write the rubric

    Bring your own rubric or pull one from the shared library. Criteria, levels, and point values — the same ones you’d use on paper.

  2. 02

    Students submit

    Give students a class code. They write (or paste) their essay. No account required. You set the revision cap.

  3. 03

    Ruberis reads + proposes

    Claude grades each submission against your rubric, citing the sentences that drove each score. Every response is logged.

  4. 04

    You approve + release

    Review the proposed score. Override anything you disagree with. Hit release. Students see only what you approved.

1. Your rubric stays yours

Ruberis doesn’t invent rubrics. You paste or build the one you already use, criterion by criterion. It’s snapshotted to each assignment so late rubric edits never change already-graded work.

2. Students write; no accounts needed

Students go to ruberis.com/join, enter the class code you share, and submit. We only ask for what you tell them to enter — typically a name or a student ID. No email, no password.

3. Claude grades against your rubric

Our grading worker reads each essay, matches language against each rubric criterion, and proposes a best-fit score. Ties go to the lower score. Every response includes the sentences that drove it.

4. You review before students see anything

Proposed scores live in your teacher dashboard until you approve them. Override, comment, or send back for revision. When you release, students see the final score you approved — never an AI-only result.

Revisions are built in, not bolted on

Set a revision cap on the assignment. When you release feedback, students get the per-criterion comments and can resubmit. Each cycle is logged. You see progress over time, not a single snapshot.
