Mark responses fairly, with feedback that helps
Add a question, a student response and an optional marking rubric, and Orpheus returns a fair mark with clear reasoning, specific strengths, concrete areas to improve and a model answer to learn from.
What you can do
Marked against your rubric
Provide your own marking criteria and responses are judged against them, consistently and with justification for every mark.
Strengths and next steps
Each result lists what was done well and gives specific, actionable improvements rather than vague comments.
A model answer
Every response comes back with an improved, full-marks answer the student can learn from.
Reads handwriting too
Upload a photo of handwritten work or a file, and Orpheus reads it as part of the marking.
A mark you can defend
Anyone can put a number on an essay. The hard part is explaining it. Every mark Orpheus gives is tied back to the rubric you provided, criterion by criterion, so a student can see where each mark was earned or lost and a teacher can stand behind the grade.
- Criterion-level reasoning
The result walks through your rubric and says how the response performed on each point.
- Strengths first
What the student did well is named specifically, so good habits get reinforced instead of lost.
- Improvements they can act on
Next steps are concrete: restructure this paragraph, quote the source here, show the substitution step.
- Adjustable strictness
Choose lenient, standard or strict marking to match a formative check or a final assessment.
How it works
Add the work
Paste the question and the student response, or upload a photo or file of the answer.
Add the rubric
Optionally include your marking criteria and the total marks available, and choose how strict to be.
Get the mark
Receive a justified mark with strengths, improvements and a model answer.
Made for real study
Mark your own practice answers before the real thing, and learn the gap between what you wrote and full marks.
Keep marking consistent across a whole stack of scripts, with reasoning you can check and adjust.
Turn a student's homework photo into detailed written feedback in the time it takes to read it.
Get more out of it
- 1Paste the same rubric every time you mark a set of responses. Consistency comes from stable criteria.
- 2Include the total marks available. The reasoning gets sharper when it knows what each mark is worth.
- 3Use strict mode before a final exam and lenient mode early in a topic.
- 4For handwritten work, photograph the page straight-on in good light. It reads better and marks faster.
Included with every account
Full marking with reasoning, strengths, improvements and model answers. Each marked response counts toward your monthly allowance.
When you need more
Unlimited marking, plus automatic marking of whole class assignments with per-student analytics.
