Matter vs Omnivore

Matter is a read-later app for collecting articles, threads, PDFs, YouTube videos and podcast episodes. It is available on iPhone, iPad and the web, and can save content through mobile and web extensions. The free plan includes an unlimited read-later library, unlimited tags and full-text search; offline reading is available by default. Newsletters can be connected through Gmail or a unique Matter email address.

Matter turns YouTube and podcast episodes into text synchronized with playback. Readers can highlight content, export highlights, send articles to Kindle and sync highlights to Notion, Obsidian, Roam, Readwise and other services. Premium adds HD text-to-speech, highlighting, note-taking, integrations and personalization; its listed plans are $8 a month or $60 a year. Premium also lists AI Co-Reader and Send to Kindle. Monthly and annual subscriptions renew automatically unless disabled at least 24 hours before the period ends.

Omnivore is an open-source read-it-later service for saving articles, newsletters, PDFs, and documents for focused reading. It supports notes, highlights, and synchronization across devices, with labels, filters, and indexed text search to organize saved material. An email inbox can receive newsletters, PDFs, and article emails, including Substack newsletters. Browser extensions and mobile apps are available. On iOS, text-to-speech includes offline audio downloads. Plugins synchronize saved reading, highlights, and notes with Logseq and Obsidian. Rules can trigger actions when articles are created or changed, but remain a web-only beta feature. The project can be extended or deployed on a user's own server; its Docker setup includes PostgreSQL, a web frontend, an API server, and a content-fetching service. The cloud application was deprecated in November 2024, so Omnivore is now self-hosted. The Free (self-hosted) plan is free. Omnivore and its Readability.js extensions use the AGPL-3.0 license.
