ExamCat

Students today piece together many separate tools to study: a flashcard app, a notes app, a video in another tab, and an AI chat that has to be re-explained the whole course each time. This fragmented workflow makes studying feel like managing a stack of apps rather than actually learning. Existing flashcard tools like Quizlet were useful for memorization in simpler subjects, but as topics become more complex, flipping a card is not enough to understand why an answer works or how ideas connect. Students lack a single place that adapts to their material, goals and level.

ExamCat brings study tools into one place centered on an AI study companion called Junko, which works with a student's own material, goals and grade level to explain concepts, generate practice, and suggest what to tackle next. The platform offers unlimited flashcards and practice quizzes, and can turn a YouTube lecture into flashcards, quizzes and lecture notes, or turn a recorded lecture into study material. It can also convert a student's own notes into a podcast for listening on the go, and includes 3D study diagrams to help visualize how parts of an idea relate. Other listed features include a quiz generator, AI test maker, AI lecture note taker, PDF summarizer, and video summarizer, alongside a live study room concept for group studying with the AI tutor.
