Cubox is an AI-powered read-it-later app for people who save far more articles than they ever get back to. Instead of letting links pile up in browser tabs, feeds, and chat threads, Cubox collects articles, web pages, and newsletters into one clean library, then layers AI summaries, semantic search, and question-answering on top so what you saved stays findable and actually useful.
Cubox is built around a simple loop: save from anywhere, read with focus, and let AI help you make sense of what you kept. Content arrives from the browser, the phone share menu, or email, and is stored with a clean article view and a web page snapshot. Highlights and notes sit alongside the source, and the library syncs across iPhone, iPad, Mac, Android, and the web. Where most read-it-later apps stop at storage, Cubox treats your library as a knowledge base: its AI can summarize long pieces, answer questions across everything you have saved, surface connections between articles, and deliver scheduled briefs built from your recent reading.
Cubox is free to start on any device. The Pro+AI plan unlocks the full AI feature set, and every account can try Pro+AI free for 14 days before a subscription begins. Because the free tier covers core saving and reading while the AI tools sit in the paid plan, Cubox is listed here as Freemium.
Cubox suits curious readers, students, and researchers who save articles, newsletters, and papers faster than they can process them. It works especially well alongside a notes app like Notion or Obsidian: Cubox acts as the AI-assisted reading inbox, and the highlights and ideas worth developing can be synced or exported into your main notes.
