The Science of Comparative Judgement
Why "Better/Worse" beats "7 out of 10"
Humans are notoriously bad at absolute judgement. We struggle to consistently score a piece of work against a complex rubric.
However, we are highly accurate at Relative Judgement. We can instantly spot which of two items is "better."
1
Upload Items
Portfolios, video interviews, essays, code, or audio. Any file type is accepted.
2
Compare Pairs
Judges see two items side-by-side and simply decide: "Which is better?"
3
Get Validated Data
Our algorithm generates a highly reliable rank order (0.9+ reliability) and actionable performance data.

The Validation Layer: Why AI Needs a Human Anchor to be Safe
We are currently living through an "Assessment Arms Race." On one side, students and job candidates are using Generative AI (like ChatGPT) to produce "perfect" essays and CVs in seconds. On the other side, institutions are rushing to buy AI marking tools to grade that work just as fast. It is a closed loop of machines grading machines. And in the middle of this loop, the human element - the actual understanding of quality - is quietly disappearing.

The Myth of the "Perfect Photo": Why Mobile Capture can be Fairer, Faster, and Just as Reliable
We assume that a blurry photo hides the quality of the work. We assume that if a drawing is photographed under yellow classroom lights, the examiner will think the drawing itself is yellow. We assume that Image Quality = Assessment Quality. But science suggests we are worrying about the wrong thing.
