What is Cubox?
Cubox is the intelligent read-it-later app designed for those who want to do more than just save content—they want to understand and recall it. It directly solves the problem of information overload, transforming your growing list of articles, newsletters, and notes from a passive archive into an active, searchable knowledge base that works for you.
Key Features
🧠 Ask Your Entire Library with AI Get precise, synthesized answers from everything you’ve ever saved. Instead of manually searching for keywords, you can ask complex questions in natural language (e.g., "What were the key arguments about AI ethics from articles I saved last year?") and receive instant, context-aware responses.
⏱️ Receive Automated AI Briefings Stop letting unread articles pile up. Cubox can take a batch of your saved links—like 30 articles on a specific topic—and distill them into a concise 5-minute summary. You can schedule these personalized briefings to stay informed without the overwhelm.
📥 Capture Everything That Matters, Effortlessly With over 10 extensions and integrations, you can save content from virtually anywhere. Seamlessly capture web articles, newsletters via a dedicated email address, highlights, and even quick thoughts as memos. Cubox’s advanced parsing and snapshot features ensure a clean, permanent archive.
📖 Enjoy a Focused Reading Environment Read your saved content in a clean, customizable, and distraction-free interface available on native apps across all your devices. Adjust fonts, themes, and layouts to create your perfect reading space, and use the powerful highlighting tools to mark what’s most important.
