Clearview is an education and reference application that provides users with a comprehensive library of educational and reference material. The application is designed to help users to quickly access and browse through educational materials such as course material, books, e-books, videos, and other reference material. Clearview also provides users with a personalized learning experience, allowing them to customize their learning experience based on their interests, goals and preferences. The application also provides users with access to a community of experts who can help answer questions and provide advice. Additionally, Clearview offers content recommendations and personalized study plans to help users stay on track with their learning goals.
Calibre does not allow annotation of documents like Clearview does. It by no means replaces it, but makes it a good organizational tool.
