Course Hero is a study platform that combines millions of student-shared course documents with AI homework help and tutors. The library holds about 184 million documents, 77 million answered questions and material from 130,000 institutions, organized so you can find notes, past exams and assignments for your own school and course. Alongside the documents, it offers textbook solutions, literature study guides, flashcards, a math solver, a grammar checker, a paraphraser, a proofreader and a spell checker. A Premium account adds AI-powered answers, explanations, recommendations, full document access and one-click tutor help.
University and high school students are the main audience, especially those who want material tied to a particular class or professor. Learners stuck on a hard problem can ask an expert tutor at any hour, while students who prefer self-study can browse notes and past exams. Teachers and tutors can also use the resources, and the mobile app lets anyone study on the go with a snap-to-solve math feature.
Typical scenarios include searching for lecture notes before an exam, viewing a past assignment to see how a similar problem was solved, asking a finance question and receiving a worked answer from a verified expert, and checking a draft with the proofreader before submitting. A student in a chemistry course might open study guides for the exact class, review expert explanations, and make flashcards to memorize terms. Users can also upload their own documents to share. Integrations such as Quillbot writing tools and the Symbolab math solver extend the set of study helpers.
