Matter is a beautifully made read-later app, but it does less than Readwise Reader and there's no public API for scripting. Here's what to consider if you want more reach or more power-user tooling.
Matter users tend to look elsewhere for the same reasons: they want a public API for integrations, they want PDF or EPUB support, or they want RSS and newsletter intake without paying for Premium.
Readwise Reader is the obvious alternative if you want more power; Instapaper if you want less. Keep is the agent-ready option. Ordered by best match. Keep shows up where it ranks, we don't push it up the list.

Here's how Matter compares to the best alternatives on the things that usually decide a switch: API access, RSS, export formats, and AI.

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.
Both. The free tier covers unlimited saves, parsing, web + mobile extensions, and unlimited tags. Premium at $8/mo or $60/yr adds HD text-to-speech, the AI Co-Reader, newsletter sync, RSS feeds, unlimited highlights, Kindle send, and integrations.
Yes, but the homepage emphasises iPhone, iPad, and web. The Android app exists but parity with iOS has historically been lower. If Android is your primary platform, verify your must-have features before committing.
No. Matter does not publish a public API. If programmatic access is a requirement, Readwise Reader, Raindrop, or Keep are all better fits.
Readwise Reader for features; Instapaper for simplicity. Neither has Matter's typography or its TTS, but both win on platform reach and integrations.
None match Matter's HD TTS directly. Readwise Reader has TTS with human-sounding voices. Instapaper Premium has AI voices. If TTS is the main reason you used Matter, these are the closest alternatives.
Matter supports exporting highlights and notes to Readwise, Notion, and Obsidian. There's no bulk article export as markdown, so migration is via re-saving in the new tool or importing your highlights.
Not directly. Matter doesn't publish an HTML or CSV export of saved articles. If you're switching, consider it a clean start in the new tool, or pull highlights via the Readwise integration if you had one.
Raindrop Pro at $3/mo is the cheapest paid tool in the category, though it's a bookmark manager not a reader. Instapaper at $5.99/mo is a cheaper pure read-later option. Readwise Reader at $9.99+/mo is pricier but more feature-rich.
Readwise Reader has the most polished newsletter workflow. Matter Premium covers newsletters too. Keep also has a per-user newsletter email address. Inoreader handles newsletters at the Pro tier.
Raindrop and Keep both have official MCP servers. If you want agent-ready access to your library, those are the only two active tools with that out of the box.
