Readlang languages: what the 100+ list means for Greek, Japanese, Korean and yours

More than a hundred languages, on a list nobody publishes in full

The number Readlang gives is 100+. In June 2024 it added 58 languages in one release and switched the AI explanations on for every one of them, which is the change that made Readlang a serious option for languages most apps ignore. The full list of reading languages is not published as a single page on readlang.com; you see it in the language picker once you have an account. That is why the table below only marks what we could verify.

Two narrower lists sit inside the big one. Uploading your own audio, with automatic transcription, is a Premium feature available for around 60 languages. The higher-quality Readlang voices, used for read-aloud on the paid plans, cover around 90. Both are explained on the Readlang audio page; for choosing a language, the thing to know is that reading is the widest circle and audio is a smaller one inside it.

A note on searches typed in other languages. People search for readlang deutsch, readlang español, readlang italiano or readlang francais, and usually mean one of two things: does it work for German, Spanish, Italian or French, to which the answer is yes; or is the interface available in that language, which the pricing and features pages we checked do not say either way. This page answers about content languages only.

Checked 14 September 2026. Readlang reads all of these. "Audio upload verified" means the language appeared on the transcription list we saw; "not verified" means we did not see it listed, not that it is missing, since around 60 languages have audio upload. The Readlang Mobile column is the Apple Translation list on iOS 18.

The right-hand column is the whole difference between the two products in one glance. Everything else on the comparison page matters only after your language clears it.

Learning more than one language at once

Readlang charges per account, not per language. The free plan, Premium at $6 a month or $48 a year, and Premium Plus at $15 a month or $120 a year each cover every language Readlang supports, and you switch between them inside the reader. A learner keeping Greek alive while starting Japanese pays once. What each plan limits, the daily phrase counter and the AI explanations on the free plan, the audio hours on the paid ones, is set out on the pricing page; none of those limits is per language.

Readlang Mobile works the same way within its shorter list: you pick any pair from the Apple Translation list and change the pair in the app when you switch books. The free plan gives 30 translations a day across everything you read; Premium removes the counter. Neither product prices by language.

Greek, and other languages outside the mainstream twenty

Checked again on 19 September 2026: Greek, Czech, Hebrew, Finnish, Swedish and Hungarian are still read in Readlang and still absent from Apple Translation, so a native iOS reader cannot help there.

This section is for the strongest search that brings people here. Readlang supports Greek for reading, and Greek is on the list of languages with audio upload and transcription. The same is true of Czech, Hebrew, Finnish, Swedish, Hungarian and Latin, and of Ukrainian and Kazakh; Uzbek appears on the voices list. For every one of these, Readlang is the answer, and it is one of very few click-to-translate readers that has the language at all.

Readlang Mobile is not the answer for them. The app offers only the languages Apple Translation supports on the device, and Apple has not shipped Greek, Czech, Hebrew, Finnish, Swedish or Hungarian in that framework as of iOS 18. We would rather say so here than let you install the app and find out. If Apple adds a language, it appears in the app; until then, the practical setup for Greek is Readlang in a desktop browser, or readlang.com pinned to the home screen on a phone, as described in the Readlang guide.

The honest summary of the trade: a hundred-plus languages reached through a browser, or about twenty reached through a native app. Which side of that line your language falls on settles the question before any feature comparison does.

Languages with a different script: Japanese, Chinese, Korean, Arabic

Reading in a language that does not use the Latin alphabet raises questions Spanish and German never do: where a word starts and ends when there are no spaces, what a character means on its own against what it means in a compound, how a root shows through an Arabic word. Readlang has supported these languages for years, and since 2024 the AI explanations in context work in all of them, which is the tool that answers the second and third questions: ask why a character in a compound means what it does and you get a paragraph, not a dictionary line. The free plan allows ten explanations a day; Premium removes the limit. The Readlang tutorial shows where the explanation button sits.

Readlang Mobile covers Japanese, Chinese in Simplified and Traditional script, Korean and Arabic because they are on the Apple Translation list, along with Hindi, Thai and Vietnamese. Tap a word for its translation, tap the first and last word of a phrase for the phrase. We are not going to make claims here about how well word boundaries are handled in Japanese or Chinese text; that is something to judge on a real page. The sample texts include Korean and Arabic, so you can look before installing anything.

Where the phone version wins

For the twenty languages it covers, Readlang Mobile has two things Readlang does not. The first is the option of translating on the device. By default, translation comes from Google Translate through the app's server; in Settings you can switch to Apple Translate, which runs on the device. Without a connection the app switches to Apple Translate, which translates on the device if the language pack for your pair is downloaded; a book has to be opened online once. Readlang cannot translate offline in any language, as the offline page explains. The second is a library sorted by level, A1 to C1, so the first book is not chosen by guesswork.

The library is built from public-domain books, and that shapes what is in it. Public-domain literature is deep in some languages and thin in others, so how much you find at A1 varies by language, and we would rather you check than take our word for it. The sample texts page has a passage for each of ten languages, English, Spanish, French, German, Italian, Portuguese, Russian, Korean, Arabic and Turkish, showing the kind of text the reader gives you. Some library books come with narration and word highlighting; your own DRM-free EPUBs open on Premium in any language on the list.

What Readlang has and the phone does not, in every language: the browser extension that makes any web page clickable, YouTube with transcripts, audio upload, flashcard export to CSV, and the hundred-language list itself. If you need any of those, the language table above is not the deciding row.
