Built by a student,
for students.

Hi — I'm a high schooler, and I built StudyStacks.

StudyStacks is a free study resource with quizzes, flashcards, practice tests, and an AI-powered study assistant to help you work through them.

I built StudyStacks because I wanted a simple, easy to access and use database of study guides for everything — rather than searching through PDFs or paying for apps with guides I can't customize or edit.

StudyStacks is completely free, and it's going to stay that way. If you have any requests for StudyStacks, or want to tell me about a class you think we need a study guide for, feel free to contact me here, or at .
