The short answer

Readwise Reader and Matter are both modern read-later apps that handle articles, newsletters, feeds and video transcripts. Readwise Reader suits heavy readers who highlight a lot and want a cross-platform library on web, iOS, Android, Mac and Windows. Matter suits iPhone and iPad readers who like to listen as much as read, thanks to its natural text-to-speech. The biggest difference is Reader's breadth and platform reach versus Matter's iOS-first, listening-first design.

Matter or Readwise Reader: our take

Readwise Reader brings saved articles, PDFs, EPUBs, email newsletters, YouTube videos with transcripts, podcasts, RSS feeds and X threads into one library. Highlighting and annotation are central, both in the app and on the open web, and highlights sync to Notion, Obsidian and other tools. Ghostreader AI can summarise and answer questions, and text-to-speech is included. Power users can drive it from the keyboard or connect AI agents through its API, CLI and MCP server. The number of features means it takes a while to learn.

Matter is made by a small team for people who read on iPhone and iPad. You can save articles, threads and PDFs, bring in newsletters through a Matter address or a Gmail connection, follow writers and feeds, and turn YouTube videos and podcasts into time-synced transcripts. Its best-known feature is very natural text-to-speech that turns your queue into a listening playlist, with highlighting while you listen. Highlights sync to note-taking tools. It runs on iPhone, iPad and the web, with no Android or native desktop app.

Pricing models differ. Reader has no free plan after its 30-day trial: it costs $7.99/month, billed yearly, on its own, or $9.99/month, billed yearly, bundled with Readwise. Matter has a free tier, with a Premium subscription unlocking the higher-quality voices and integrations.

Choose Readwise Reader if you use Android or a desktop computer, read many formats, and want highlights to feed a research or note-taking workflow. Choose Matter if you are on Apple mobile devices, enjoy listening to articles, and want to start on a free tier.

What is Matter?

Matter is a read-later app built by a small team, aimed at people who read a lot on iPhone and iPad. You can save articles, threads and PDFs from the browser extension or share sheet, pull email newsletters in through a Matter address or a Gmail connection, and follow writers and feeds so new posts arrive automatically. It can also save YouTube videos and podcast episodes and turn them into time-synced transcripts. The app's best-known feature is text-to-speech with very natural voices, which turns your queue into a listening playlist, and you can highlight while listening. Highlights sync to note-taking tools, and quoteshots make it easy to share passages as images. Matter has a free tier, with a Premium subscription unlocking features such as the higher-quality voices and integrations. It runs on iOS, iPadOS and the web, but there is no Android app, which rules it out for many people.

What is Readwise Reader?

Readwise Reader comes from the team behind Readwise, the service that collects highlights from Kindle and other sources. Reader puts everything you might want to read in one library: saved web articles, PDFs, EPUBs, email newsletters, YouTube videos with transcripts, podcasts, RSS feeds and X threads. Highlighting and annotation are the core of the app, both inside Reader and on the open web through its browser extension, and highlights can flow into Notion, Obsidian and other note tools. The Ghostreader AI can summarise, define terms and answer questions about a document, and text-to-speech reads articles aloud. Reader runs on the web, iOS, Android and desktop apps for Mac and Windows, and power users can drive it from the keyboard or connect AI agents through its API, CLI and MCP server. There is no free plan after the 30-day trial; you can subscribe to Reader alone or to a bundle with Readwise highlights review. It is best for heavy readers who want to keep and reuse what they read.
