Grade a whole class to your rubric — twice-checked, in minutes.

Duograde marks every student's script with two independent AI graders that must agree, then hands you the marks in a spreadsheet and ready-to-send feedback for each student. Consistent, defensible grades — without the all-nighter.

Why two graders

Double-marking, built in.

In higher ed, the safeguard for fair marking is a second marker. Duograde does it automatically: two independent AI graders score every answer, agree on the mark, and flag the ones they disagree on for your review.

  • Consistent — the same standard applied to every student, every question.
  • Defensible — a full audit trail of each grader's mark, so grades hold up to appeals.
  • Fair — divergent marks are surfaced, not silently averaged.
What you get

Everything a marker actually needs.

📋

Mark to your rubric

Build it in seconds, upload a Word/PDF rubric, or let Duograde infer the questions. Mix rubric-marked and judgment questions.

🔢

Questions & sub-parts

Marks per question and per sub-part (3a, 3b, 3c), with subtotals — not just one number per script.

📈

Curve to a target

Set a target average and Duograde scales the cohort to it, keeping the raw marks alongside for transparency.

💬

Feedback per student

A Word document with one student per page — specific, per-question feedback you can paste straight back to them.

📊

Marks in Excel

A clean spreadsheet plus an audit sheet showing every grader's mark and which rows to double-check.

🔒

Private by design

Student files are deleted as soon as your results are generated. You're grading your own students' work — it stays yours.

How it works

Three steps, one download.

1

Upload the batch

Drop in the whole class — PDF, Word, or an LMS export (Moodle, Canvas, Turnitin). IDs and names are read from the files.

2

Set your rubric

Build it online, upload one, or skip it and let Duograde work to your standard. Add a target average if you mark to a curve.

3

Download results

A zip with the marks spreadsheet, per-student feedback doc, and the renamed scripts — cross-referenced so every grade traces to its file.
