Cubox

Cubox is an AI-powered read-it-later app that helps you save web articles, newsletters, and other content, then find and understand what matters. Instead of just bookmarking links, Cubox lets you ask questions about your entire library and get instant answers, even from items saved years ago. It also offers personalized AI summaries that turn a stack of unread articles into a short brief you can read in minutes.

The app works across platforms with native apps for Mac, iPhone, iPad, Android, and browser extensions for Chrome, Firefox, Edge, and Safari. You can save content with one click, highlight key passages, and organize everything with tags and folders. The AI features stand out: you can query your library in natural language, and Cubox will pull relevant snippets from saved pages. The swipe-based review system helps you quickly clear unread items, focusing on what's worth reading deeply. Cubox also integrates with tools like Obsidian, Notion, and Readwise, so your saved content can feed into other workflows.

Cubox is best for anyone who saves a lot of online reading material — researchers, students, journalists, or curious readers. It solves the problem of having too many bookmarks and not enough time to revisit them. Use it to keep a personal knowledge base that you can search and summarize, rather than just a list of links. If you're coming from Pocket, Cubox offers an import tool to bring your existing library over.
