About Matter
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.
About SMRY
SMRY started life in late 2023 as an open-source paywall bypass tool that piped articles through archive.org and ran a ChatGPT summary on top. Two years on it has been repositioned as a full AI reading app. You paste a URL (or prepend smry.ai/ to it) and get a clean reader with 11 themes, an AI summary, text-to-speech in up to 10 voices, highlights in 5 colors, an article chat, and a YouTube transcript mode. The product is intentionally narrow. There is no personal library, no inbox, no RSS, no auto-sync from anywhere, and no mobile app. The pricing matches that scope: free with a daily summary cap, or $3 per month on annual ($6 monthly) for unlimited summaries, the premium voice, highlight export, and ad-free reading. The Chrome extension is optional and captures from your authenticated session so JS-rendered and paywalled pages render cleanly.
