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.
Dewey is a niche tool aimed at one specific problem: saving and organising bookmarks from social platforms. It ingests from X, Bluesky, LinkedIn, Threads, TikTok, Instagram, Reddit, Mastodon, Substack, and Truth Social, and puts them in a unified library with AI auto-tagging and nested folders. Browser extension (Chrome) and web app only, no native mobile. Pricing: Free (manual sync, one account), Pro at $10/mo monthly or $7.50/mo annually, Lifetime at $225, and an $8.50 one-off 'Export Pass' that unlocks the export feature for 48 hours without a full subscription.
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.
