The short answer
ReadHatch is Accelerated Reader for use at home. It's a parent-purchased app for iPhone and Android that gives kids a 10-question AI-generated comprehension quiz on anybook they finish — whether or not their school runs AR, and whether or not that book is in AR's catalog. If you want the "prove you read it" part of school reading programs without needing a school, this is it.
Accelerated Reader (AR) is the classic school-purchased comprehension-quiz program. If your kid's school uses it, you already have it. If they don't, you can't buy it as a parent.
AR scanner apps — BookScanner, Points Scan, AR Reading List, AR Book Assistant — scan a book's barcode and tell you its AR level, point value, and quiz number. They are lookup tools. None of them can give your kid the quiz. ReadHatch scans the same barcode and then actually produces one.
ReadnQuiz is a long-running web alternative to AR with a homeschool edition, and its ReadCheck iOS app generates AI quizzes from a photo of the page your kid is on. It's the closest thing to a direct rival, and it works at the passage level rather than the whole-book level.
Raz-Kids is a teacher-assigned leveled reading tool. Access is issued by the classroom.
Epic! is a kids' digital reading library — its main value is the catalog of books, not the quizzes.
Beanstack and ReadingTime are reading logs. They track that a book was read and for how long. Neither checks whether the kid understood it.
