Instapaper vs Readspace

Instapaper saves internet content for later reading and organization. A single action can save articles, videos, recipes, song lyrics, and other pages; saved articles and videos sync across supported devices and can be read offline. Readers can highlight and comment on article text, then store, retrieve, quote, and share selected passages. The free plan includes unlimited article, video, and page saves, folders, synchronization, and API integration, with a limit of five notes per month. Premium adds full-text search, a permanent archive of articles, PDF reading, unlimited notes, Kindle integration, and mobile AI Voices and text-to-speech playlists. Premium costs $5.99 a month or $59.99 a year. Supported platforms include the web, iOS, Android, macOS, and a Chrome extension; listed devices also include Kindle, Kobo, and Boox eReaders. Speed reading is listed as processing articles up to three times faster.

Readspace brings followed publications, writers, and newsletters into a reading feed and creates a five-minute daily briefing. The chronological feed contains sources a user follows, without engagement ranking or suggested posts. Its Daily Digest groups coverage of the same development across selected sources and links to them. Readers can explore more than 120,000 sources and import or export subscriptions as OPML. A browser extension can find a site's RSS feed when available. Reading tools include summaries, key-point highlighting, and translation. Newsletters can be received through a private Readspace email alias and placed in a Newsletters folder. The maker says reading has no ads or trackers and that reading activity is not sold or used for targeting. Readspace is open source and can be self-hosted; that option has no usage limits, but lacks the hosted catalog, requires OPML imports, and bills AI through the user's provider. Basic is free with limits on feeds, saved articles, and daily tools. Pro costs $5.99 a month, billed monthly, with fair-use limits.
