Zuoyebang
Homework help and AI study devices
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 — Photo-search homework help — OCR + image recognition match a photographed problem to a large solution database — plus a live-class arm.
Why it was built — Convert Baidu search expertise into search-by-photo homework help, then monetise the huge free base via live K-12 tutoring.
