Cubox is your AI read-it-later app. Save once, know forever. Cubox helps you recall and make sense of what matters.

Every day, we save articles and materials we want to read later — but often never get back to them. Over time, they pile up unread, unorganized, and eventually forgotten.

Cubox has been dedicated to building a reading tool designed to stand the test of time: seamless collecting, immersive reading, and AI-powered understanding that continuously transforms your saved content into growing knowledge assets.
