Course Hero is an online learning platform that gives students access to a community-driven library of course-specific study resources, including class notes, study guides, practice problems, and step-by-step explanations. Content is contributed by students and educators, and also produced by in-house educational content specialists in collaboration with subject experts. The platform spans academic subjects from economics and biology to psychology, accounting, history, and more.

AI-powered tools are central to the platform experience. Students can upload any document and use the AI Chat feature to ask questions about its contents, while an AI homework help assistant provides answers and explanations across a broad range of question types. For more personalized support, students can connect with verified expert tutors who are available around the clock to assist with specific questions and concepts.

Course Hero offers a free Basic membership alongside paid Premier plans. The Premier plan includes course-specific resource access, AI Chat with PDFs, expert tutor questions, and unlimited textbook solutions. The Premier Plus plan, also referred to as the Study Bundle, extends this with a paraphraser, citation generator, grammar checker, step-by-step math solver, math word problem solver, graphing calculator, and geometry problem solver.

Students can upload their own study materials to earn free access to resources within the Course Hero library. The service is accessible through a web browser and via dedicated iOS and Android mobile applications.
