What is Cubox?

Cubox is a read-later app from Zenbox Inc. that saves articles, newsletters and web pages into a private library, parses them into a clean reading view and keeps a snapshot of each page. Readers can highlight and annotate, organize with nested folders and tags, and use AI to summarize an article or ask questions across everything they have saved. A basic account is free, and the Pro and Pro+AI memberships are sold on the web as annual plans.

Cubox has a free plan. Paid plans start at $29 per year (Cubox Pro, annual plan). See every plan

Good for

  • Readers who save articles, newsletters and web pages to annotate later
  • People who want AI summaries and answers drawn from their own saved library
  • Users who send highlights on to Obsidian, Notion or Readwise

Worth knowing

  • The free basic account has a quota on saved content, and the vendor pages read do not say how large it is.
  • The web pricing page offers annual plans only: Pro at $29 a year and Pro+AI at $49 a year. The US App Store listing also shows monthly in-app purchases.
  • AI Insight and Ask AI need a paid membership and have usage limits; automatic insight is reserved for Pro+AI.
  • The download page lists Mac, iPhone, iPad, Android and browser extensions; on Windows and Linux Cubox runs as a web app.

Key features

Saving from many places
Browser extensions for Chrome, Edge, Safari and Firefox, the share sheet on iPhone, iPad and Android, a Mac helper, Email Drop and an API all save content into one library.
Article parsing and snapshots
Saved pages are parsed into a clean reading view with adjustable themes and fonts, and a permanent snapshot keeps the page readable if the original link dies. Snapshots are for Pro members.
Highlights and annotations
Highlight passages and add notes while reading, then review them later through widgets and reminders. Multiple highlight colors are part of the Pro plans.
AI Insight and Ask AI
AI Insight gives an article a short summary, key questions and automatic Ghost Highlights, and Ask AI answers follow-up questions. Automatic insight on newly saved items comes with Pro+AI.
Folders, tags and search
Nested folders and tags, smart folders, batch editing and full-text search organize the library. The help center lists nested folders as exclusive to Pro members.
Export and integrations
Content exports as Markdown, HTML or PDF, and collections and annotations sync to Notion, Readwise and Obsidian. Third-party integrations are a Pro feature.
