Ednius
AI grading software for universities, built by a professor who uses it
Ednius is AI-assisted grading and feedback software for higher education. It grades open-ended student work against your rubric in minutes and writes personalized feedback for each student. The instructor reviews, adjusts, and approves every grade before it is published.
I co-founded Ednius in 2024 and use it in my own courses at Simon Fraser University.
AI-assisted grading, with the instructor in control
- Submissions graded
- 60,000+
- Accuracy
- 97%
- Instructor time saved
- ~70%
- Student satisfaction
- 95%
Ednius is used by universities and certification bodies in North America and Asia. Educators spend 10 to 22 hours a week grading per course, and students often wait weeks for feedback that is too generic to act on. AI-assisted grading returns specific feedback while the material is still fresh.
How the AI grading software works
-
Connect
Link your Canvas account in one click. Blackboard, Moodle, and other learning management systems are available on request.
-
Configure
Add a rubric, or describe what you are looking for in plain language, and set your grading preferences.
-
Grade
Review the AI-generated grades and feedback, make any adjustments, and publish to students.
From essays to equations
- Essays and short answers, including the quality of reasoning and valid alternative approaches
- Math and equations
- Code
- Diagrams
- Handwritten and typed work
Subjective and objective questions are handled on one platform. Each response receives its own feedback, which explains what went wrong and how to improve, and class-level analytics show where students struggle.
What to ask of any AI grading tool
Four principles anchor Ednius. They are also reasonable questions to put to any AI grading software you are evaluating.
Who makes the final decision?
Educators retain final decision-making authority. In Ednius every grade can be reviewed, edited, or overridden before it is published.
What happens to student data?
Student privacy is protected. Ednius does not store students’ personally identifiable information or use it to train AI, and it is aligned with FERPA, GDPR, and SOC 2 standards.
Is the feedback useful, or only the score?
Feedback is prioritized over grades. Each student receives specific, rubric-aligned comments rather than a number alone.
Are standards applied consistently?
Evaluation standards stay consistent across assignments and graders.
Ednius is also built the way I run a study: every feature ships behind an A/B test, and design decisions follow field-experiment evidence. AI-assisted grading still raises research questions that are not settled, such as when instructors over-trust or under-trust an AI-suggested score and whether scoring differs across writing styles. I would like to study these with collaborators; see the call for research collaboration.
Questions about AI grading
What is AI grading software?
AI grading software uses large language models to score student work against a rubric and to draft feedback. In AI-assisted grading, the instructor reviews the suggested grades and feedback and makes the final decision.
How does Ednius grade student work?
Ednius uses a multi-agent AI system to score each response against your rubric, consider partial credit, and generate feedback. You can adjust any grade before publishing.
Does AI grading replace the instructor?
No. In Ednius every grade can be reviewed, edited, or overridden, and nothing reaches students until the instructor publishes it.
Can AI grade essays and other subjective answers?
Yes. Ednius evaluates essays, short answers, and complex problem-solving, including the quality of reasoning and valid alternative approaches. It also handles math, code, diagrams, and handwritten work.
How accurate is AI grading?
Ednius has graded more than 60,000 submissions and reports 97% accuracy, about 70% of instructor grading time saved, and 95% student satisfaction. For any AI grader, accuracy varies with the rubric and the type of question, so the instructor’s review remains part of the process.
Is student data used to train AI?
No. Ednius does not store students’ personally identifiable information or use it for AI training. It follows FERPA, GDPR, and SOC 2 principles and encrypts data.
Which learning management systems does it work with?
Canvas, with one-click integration. Blackboard, Moodle, and other systems are available on request.
