We're a small, family-built studio making warm, thoughtful tools for students — built at the kitchen table, tested by real kids on real homework.
Photograph the pages of any book and get friendly margin notes, vocabulary, recaps and quizzes — pitched at the reader's own level, from elementary school to college. Reading help that feels like a clever friend in the margins, powered by AI with a pencil in hand.

Play StackThat!That! Studios started with one family, one bookshelf, and a simple idea: school tools don't have to feel like school. Our apps are built with care about how kids actually read, remember and rest — and with respect for their privacy. We don't run ads, and we collect as little as possible: ideally, nothing at all.
Questions, trouble, or an idea for us? We read everything.
