Both tools do their category well, but the specifics differ. Here's what each one is good at and where it tends to fall short.
Matter is a read-later app that leans hard on typography, audio, and AI as a co-reader. The free tier covers unlimited saves, the parser, mobile and web extensions, and unlimited tags. Premium at $8/mo or $60/yr adds HD text-to-speech, an AI Co-Reader that summarises and explains, full-text search, RSS feeds, newsletter syncing, unlimited highlights, integrations, and Kindle send. The reading UI is one of the nicest in the category. The team is small, which shows in a smaller feature set than Readwise Reader but also in a more coherent product.
Readwise Reader is the reading companion to Readwise's highlight sync service. It handles articles, PDFs, EPUBs, emails, tweets, and YouTube transcripts in one inbox, with a Ghostreader AI copilot for summaries, definitions, and Q&A. Highlights sync to Notion, Obsidian, Logseq, Roam, Evernote, and Airtable. It ships as web, iOS, Android, and browser extensions, with a public REST API for scripting. Pricing is $9.99/mo billed annually (or $12.99/mo monthly) as part of the Readwise Full plan, which includes the highlight sync service. A 30-day free trial is available.
