Course Hero
Study resources and AI explanations
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 — 'Upload to study' generates explanations and practice from a student's own notes.
Why it was built — A crowdsourced library of course-specific study materials so students find help specific to their actual class.
