Matter shows up constantly in "best text to speech" roundups for read-later apps, and for good reason: its Premium tier leads with text to speech as a headline feature rather than an afterthought, which is unusual among apps built primarily for saving and organizing articles. That reputation makes it worth a fair, specific comparison against ReadLoud rather than a vague "which is better."
What Matter actually is
Matter is a read-later app: save articles from the web with a browser extension or mobile app, organize them, highlight passages, take notes, and sync everything across devices. The free tier covers an unlimited library and the core saving and organizing features. Matter Premium, at $8 a month or $60 a year according to Matter's own pricing page, adds HD text to speech, fluid highlighting and note-taking, integrations, and full-text search. Text to speech being gated specifically behind the paid tier, and marketed as a headline reason to upgrade, is a big part of why it gets called out as the best-in-class TTS among read-later apps in independent reviews. We have not tested Matter's voices ourselves, so treat that reputation as reported rather than confirmed here.
What ReadLoud actually is
ReadLoud does not save articles or build a reading list. It is a standalone text to speech tool: paste text, a link, or upload a PDF, EPUB, DOCX, HTML, Markdown, CSV or plain text file, up to 40 MB and 900,000 characters, and it is read aloud in one of 30 voices across four engines, with word by word highlighting measured from the real generated audio. There is no subscription. Credits are minutes of freshly generated audio at 1x speed: 1 minute free with no account, 20 minutes free with a sign up, then packs from $9 for 60 minutes down to $99 for 1,000 minutes. Replays of anything already generated are free.

The price math
This is the part worth doing carefully, because it is where the honest answer actually lives, not in feature lists.
Matter Premium at $60 a year works out to $5 a month, flat, no matter how much or how little you listen once you are subscribed. ReadLoud's cheapest per-minute rate, on the largest 1,000-minute pack, is $0.099 a minute. At that rate, $5 buys about 50 minutes of freshly generated audio. On the mid-size 300-minute pack at $0.12 a minute, $5 buys about 41 minutes. On the smallest 60-minute pack at $0.15 a minute, $5 buys about 33 minutes.
That means the crossover point, where Matter's flat $60-a-year price starts beating ReadLoud's per-minute cost, lands somewhere around 35 to 50 minutes of new listening a month, depending which ReadLoud pack you would otherwise buy. That is under an hour a month. Compare that to ReadLoud's own rule of thumb against a $139-a-year subscription like Speechify, where the crossover is closer to 10 hours a month, and the difference is stark: Matter is priced low enough that its subscription pays for itself fast for genuinely regular listeners, faster than most other TTS subscriptions in this category.
The flip side matters just as much. Below that 35-to-50-minute-a-month threshold, meaning you listen only occasionally, a slow month here, a busier one there, paying $60 a year for Matter means paying for a lot of unused capacity. ReadLoud's free tier plus the smallest pack could cover an entire year of light, occasional listening for less than $60 total, with minutes that never expire, so a quiet month never wastes anything.
Who suits which
If you already save articles to Matter and listen to a meaningful amount every month, more than roughly an hour, Matter's Premium tier is genuinely good value, and switching to a per-minute tool for the same volume of listening would likely cost more, not less. Its reputation for strong TTS quality, combined with the saving and organizing features you would already be paying for, makes the subscription an easy case at that usage level.
If your listening is occasional, unpredictable, or spread across things that are not saved web articles, PDFs, research papers, your own documents, ReadLoud's per-minute model avoids paying for a subscription that sits mostly unused, and it reads things Matter was never built to save in the first place.
Being fair about what each one is missing
Matter does not do research papers, your own PDFs, or arbitrary documents the way ReadLoud does, since it is built around saved web content specifically. ReadLoud does not save, tag or organize anything, and has no browser extension or native app the way Matter does. Neither one is trying to be the other, and picking based on price alone without checking whether the app even handles what you want to listen to would be a mistake in either direction.
Trying it before deciding
The fastest way to know which side of that 40-minute-a-month line you actually fall on is to track a normal week or two of listening, then compare it honestly against Matter's flat price. Try ReadLoud's free minutes to see how the per-minute cost feels in practice, and check current pack pricing since it can change during the open beta.
