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 Raindrop
Raindrop is a bookmark manager with polished apps on every major platform, a generous free tier with unlimited bookmarks, and a surprisingly thorough AI layer for Pro users. Pro is $3/mo ($28/yr) and unlocks full-text search across saved pages and PDFs, the Stella AI assistant, a permanent web archive, reminders, and annotations on highlights. Highlights themselves are free on every tier. The product quietly got ambitious on AI in 2025. There's an official MCP server at /rest/v2/ai/mcp that works with Claude, Cursor, ChatGPT, VS Code with Copilot, Windsurf, and Zed, plus an open REST API with OAuth and token auth.
