101.school

101.school is a web platform that creates custom online courses on demand. A user types in a topic they want to learn, and the site uses GPT-4 to generate a structured course, typically spanning several weeks, that can be read on the site or delivered by email. Courses are organized by broad subject areas, including sciences, engineering and technology, the arts, social sciences, health, business, and interdisciplinary studies, and cover everything from technical skills like Python and SQL to hobbies like brewing and knitting, professional certifications, and academic subjects like physics and philosophy. Alongside self-generated courses, the platform hosts a browsable library of courses already created by other users, so visitors can enroll in existing content instead of generating something new. Each course includes an embedded chat window where learners can ask the AI to quiz them on the material, request practice exercises, or point them to further reading, turning a static syllabus into something closer to an interactive tutor. It also tracks a learner's progress through a course over time. 101.school is aimed at self-directed learners, career changers, and people exploring a new interest, rather than institutions or classroom settings. Its main limitation is that course quality depends entirely on the underlying AI model's knowledge, so accuracy is not independently verified.
