Speechify and NaturalReader are two of the best known names in text to speech. Both turn documents and web pages into spoken audio, both have been around for years, and both show up constantly in "best text to speech app" roundups. But they are not the same product. Here is a fair look at where each one is strong, where they overlap, and a third option worth knowing about if you do not listen every day.
What Speechify does well
Speechify's biggest advantages are the ones that come from being a mature, well funded product. It has native apps for iOS, Android, macOS and Windows, so it runs like a proper local app rather than a browser tab. It has a browser extension that can read almost any web page with one click. It can do OCR on photographed pages, meaning you can point your phone camera at a printed page or a textbook and have it read aloud, which is genuinely useful for physical books and handouts that do not exist as digital text. Its voice catalogue is large and includes celebrity voices, which is a selling point for some users even if it does not change how well the reading works.
All of that comes bundled into a single subscription, so once you pay, most of Speechify's features are available across every device you own.
What NaturalReader does well
NaturalReader has been in this space even longer and takes a similar "cover every platform" approach. It offers a web based reader, downloadable desktop software for Windows and Mac, and mobile apps, plus a Chrome extension for reading pages as you browse. It supports a wide range of file types including PDF, Word documents and web pages, and its paid tiers add OCR for scanned or photographed pages, similar to Speechify. NaturalReader also has a genuine free tier, so you can try the core reading experience before paying for anything.
Where NaturalReader tends to differ from Speechify is tone: it reads as a utility rather than a lifestyle product, with less marketing around celebrity voices and more focus on plain, dependable reading across formats.
Where they overlap
Both apps let you upload or paste documents and have them read aloud with word highlighting so you can follow along visually. Both support multiple voices and multiple languages. Both are aimed at a broad audience: students, professionals proofreading their own writing, and people who prefer listening to reading for accessibility reasons such as dyslexia or ADHD. If you already know you want one of these two, either one will get you readable, natural sounding audio from your documents.
Pricing
Speechify Premium costs about $139 a year at the time of writing. That price changes, so check speechify.com/pricing for the current number before you commit.
NaturalReader publishes its own tiers on its pricing page, with a free plan and paid plans that unlock more voices, OCR and other features. We are not going to guess at NaturalReader's current numbers here, since third party prices change; see naturalreaders.com for what they charge today.

A third option: pay per minute
If you have looked at both of these and thought "I do not listen enough to justify a yearly subscription," there is a different model worth knowing about. ReadLoud works like Speechify or NaturalReader in the basic sense, paste text, a link, or upload a PDF, EPUB or DOCX, and it reads it aloud with word by word highlighting. The difference is how you pay: instead of a subscription, you buy minutes of audio and they never expire. A minute costs less the more you buy, from about $0.15 a minute down to under $0.10 a minute on the largest pack, and replaying anything you have already generated is always free.

Accessibility considerations
Both apps are commonly recommended for dyslexia, ADHD and other reading differences, and for good reason: word highlighting and adjustable reading speed are exactly the kind of support that helps some readers process text more easily by ear. Speechify markets itself directly at students with reading differences, and its OCR feature is particularly useful for handouts and textbooks that only exist on paper, since it turns a photo into readable, listenable text. NaturalReader is also used heavily in schools and by adult readers who want a plain, dependable reading experience without extra features to configure, and its free tier means students can try it before a parent or school pays for anything. Neither tool replaces professional support for a diagnosed learning difference, but both are reasonable low cost or free ways to test whether listening to text helps you personally before spending money on a subscription. For a broader look at this use case, see text to speech for accessibility and text to speech for students.
Which one should you pick
If you want native apps on every device, a browser extension, and OCR for physical pages, and you listen often enough to make a subscription worthwhile, Speechify is a solid, well rounded choice. If you want the same general coverage with a genuine free tier and a slightly more utilitarian feel, NaturalReader is worth trying first since you can test it without paying. If neither of those fits because you only listen for an hour or two a week and do not want a recurring charge for that, a pay per minute tool like ReadLoud is worth a look before you commit to either subscription.
