Worked out from the maker’s own published facts, checked 4 and 5 October 2026. Nobody hand-scores these. How it’s worked outlearnerfirst.com · The Four Mismatches Test

Independence: our publisher builds learning products too. We never review or score its products, and no tool pays to be listed or to rank higher — how we assess fit.

What it does

What the AI actually does — An LLM evaluates essays against a teacher-supplied or AI-generated rubric, producing a score plus targeted feedback per criterion.

Why it was built — Speed up essay grading — score against a rubric and return specific feedback in a fraction of the time.
