Eedi
Diagnostic maths built on misconception data
Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.
What it does
What the AI actually does — A diagnostic multiple-choice engine over a large bank of teacher-authored 'why' questions, surfacing the misconception behind a wrong answer.
Why it was built — Close the maths attainment gap by identifying why a student got a question wrong — the specific misconception — not just that they did.
