Cubox: AI Reader & Highlight

Cubox is an AI-powered reading and knowledge management tool that allows users to gather, organize, and annotate various types of web content. It offers features like AI summaries, full-text search, nested folders and tags, and integrations with other writing and productivity apps. The platform is designed for reading, learning, and research across multiple Apple devices.

Cubox is a strong match as it offers core functionalities for saving and organizing web content, including articles, images, and videos, with features like folders, tags, and full-text search. It supports annotations and notes, which aligns with contextual side notes. The app is available across multiple Apple devices, indicating mobile responsiveness. While it doesn't explicitly mention 'public sharing' in the same way URList does (allowing viewers without sign-up), it does have export and integration options. The AI features are an additional layer not directly covered by URList's core proposition but enhance the reading and knowledge management aspect.
