Crowdmark
Online collaborative grading
We publish a full Four-Mismatches fit assessment for the student-facing exam tools first. For this one, the facts below are what we have verified — run the Four Mismatches Test on it yourself for your own students.
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 digital collaborative-grading workflow (scan, match pages, grade against shared rubrics); AI-assisted grading is a recent add-on [mechanism TBD].
Why it was built — Online collaborative grading — digitise exams so multiple TAs grade consistently and return richer feedback.
