How we grade them
| 3.6GPACuboxExcellent | 3.6GPAMatterExcellent | |
|---|---|---|
| Value for money | APro is $29 a year for unlimited saves and highlights, snapshots, nested folders, Email Drop and the API. That's well under most read-later apps. Pro+AI is $49 a year, and Cubox's FAQ says you keep renewing it at the price you first paid. | BOn the US App Store it's $7.99 a month or $59.99 a year, which is about typical by the year and the dear end by the month. But the App Store lists several Premium and Pro prices, up to $79.99 a year, and the website has no pricing page. Hard to know what you'll be shown. |
| Free plan and trial | BThe basic account is free, but it has a quota on saved content, and Cubox's pricing page and help centre don't say how big it is. Snapshots, nested folders and the API are Pro. The 14-day Pro+AI trial wants a payment method linked first. | AThe free version has an uncapped library, saving from the phone and browser extensions, unlimited tags, full-text search and custom themes and fonts. Most people could stay on that. Newsletter sync, RSS feeds, HD speech and unlimited highlights are the paid bits. |
| Features | AIt saves from browser extensions, share sheets, email and an API, turns pages into a clean reading view and keeps a snapshot in case the link dies. Then there are highlights, notes, full-text search, and export as Markdown, HTML or PDF. The AI summaries and Ask AI sit on the paid plans. | AArticles, PDFs and threads in a clean view you can read offline. YouTube videos and podcast episodes get transcripts that stay in sync with playback. Text to speech, highlights that sync to Notion, Obsidian, Roam and Readwise, and on paid plans newsletters, RSS, an AI Co-Reader and Send to Kindle. |
| Ease of use | BThere's no App Store rating on record for it, so a B is as high as we go. Saving is the share sheet or a browser extension, and pages arrive already cleaned up for reading, with themes and fonts you can change. | A4.61 from about 1,200 App Store ratings. Save from the app or a browser extension and it shows up parsed and ready. Highlighting is a long press and a drag. |
| Platforms and integrations | AWeb, Mac, iPhone, iPad, Android and extensions for Chrome, Edge, Safari and Firefox, plus an API and syncing to Notion, Readwise and Obsidian. On Windows and Linux it runs as a web app. | BiPhone, iPad and the web, with saving extensions for Chrome, Safari and Firefox. No Android app is listed, and there's no desktop app. It links to Gmail, Kindle, Notion, Obsidian, Roam and Readwise, and has a REST API and a terminal client for Matter Pro subscribers. |
| Best for | read-later with snapshots and AI summaries | reading and listening to saved articles on iPhone |
