Freezetab vs Readspace

Freezetab saves and organizes links, articles, RSS and Atom feeds, and quotes from websites. Saved articles can be edited in a rich text editor, and content can be highlighted and searched in full text. Filters for time period, tags, sites, and data type help narrow a collection. It is available as a browser extension, on iOS, and on the web; an iOS or iPadOS shortcut can save links and quotes. The free extension supports local use without an internet connection and can be used without logging in, with data kept on the user's machine. Privacy controls let users mark saved data private so it is not sent to Freezetab’s servers, or enable privacy mode for new saves. Freezetab Pro adds cloud backup, syncing across browsers and devices, web access, saving links without the extension, and mobile link saving. Pro costs $2.99 a month after a 7-day free trial. Freezetab says its security measures include HTTPS, firewalls, IP allowlists, VPNs, and encrypted backups. Stripe handles billing information; Freezetab says card numbers and security codes are not stored on its servers.

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.
