Cogent is an AI-powered study platform that helps students create interactive learning materials from their own notes, textbooks, or documents. The platform offers three main tools: AI Flashcards that automatically generate flashcards from text or notes; File Chat that lets you ask questions and get answers with relevant quotes from uploaded files; and AI Simulated Exams that create practice tests and provide graded feedback based on the material. Cogent also includes collaboration features, allowing students to share tools and study together. It is designed to help learners study more efficiently, master subjects, and prepare for exams. The free tier provides basic access, while the Elite plan unlocks unlimited usage and advanced features.
