Readlang and ReadNative both help you read in a foreign language by letting you tap or click words you don't know. After that, they go in quite different directions. Readlang is a lightweight tool that turns almost any text, especially web pages, into a reading lesson. ReadNative is an app built around graded books that start at absolute beginner and rise step by step.
If you're deciding between them, the main question is simple: do you already have things you want to read, or do you need the app to give you things you can read?

Where Readlang is better
Reading the real web. Readlang's browser extension is its standout feature. You can be on a news site, a blog, a Wikipedia article or a forum in your target language, switch it on, and click any word or phrase to get a translation in context. You don't have to copy anything into a separate app. For intermediate learners who already spend time online in their target language, this is extremely convenient, and ReadNative has nothing equivalent.
Phrase translation. Readlang lets you select a multi-word phrase and translate it as a unit, which helps a lot with idioms and set expressions where word-by-word glosses mislead. ReadNative offers tap-a-sentence translation, which covers some of the same need, but Readlang's drag-to-select phrase lookup is more precise.
Breadth of languages. Because Readlang works on whatever text you give it, it can support far more languages than ReadNative's 20. If your language isn't on ReadNative's list, Readlang (or a similar tool) is a practical option.
Flashcards with context. Readlang's cards keep the sentence where you met the word, and it hides the word so you recall it from context, which is a smart design. Many learners use Readlang mainly as a frictionless way to generate good flashcards from their reading.
Minimal and fast. Readlang is a focused, no-nonsense tool. Some learners prefer that to a full app with its own library.
Where ReadNative is different
It solves the beginner problem. A read-anything tool is only as good as the text you feed it, and for beginners most authentic text is simply too hard. Research on lexical coverage (Hu & Nation, 2000; Nation, 2006) suggests that comfortable reading needs you to know something like 95–98% of the running words. A typical news article is nowhere near that for someone at A1 or A2. You can click every other word, but at that point you are decoding, not reading, and it's exhausting.
ReadNative's books are graded retellings: Don Quijote in Spanish, Pinocchio in Italian, The Captain's Daughter in Russian, Journey to the West in Chinese, and so on. Each one starts at very simple language and introduces new vocabulary gradually as the story continues, so a beginner can read a real narrative from the first chapter. There's more on this approach in what graded readers are and graded readers vs native books.
A path, not a blank page. With Readlang you decide what to read. That's freedom if you know what you want and a problem if you don't. ReadNative gives you a sequence: one graded book per language from A1 to around B1, and longer ladders for Georgian (13 books, up to B2 classics) and Chinese (six books, HSK1 to HSK5).
Romanization for non-Latin scripts. When you tap a word in Georgian, Russian, Arabic, Thai, Korean, Chinese or another non-Latin script, ReadNative shows a romanized form along with the gloss. That's a big help while you are still learning to decode the script itself. See how to learn a language with a non-Latin script for how to use romanization as training wheels and then drop it.
Mobile and offline. ReadNative is a phone app as well as a web app, and books can be read offline. Readlang is designed around the browser, which suits desktop reading well but is less natural on a commute without a connection.
Hand-checked graded text versus machine translation. Readlang relies on machine translation for its lookups, which is usually good but occasionally picks the wrong sense of a word. ReadNative's glosses are prepared for each book's text. That said, ReadNative's EPUB import uses AI translation chapter by chapter too, so for your own books the two tools are closer than for the built-in library.
The same word, two experiences
Imagine you're an A2 learner of German and you meet the word Ofen (oven).
In Readlang, you might meet it in a recipe blog post. You click it, get "oven", and the word goes into your flashcards with the sentence. The surrounding text may include ten other unknown words, so you click quite a lot.
In ReadNative, you'd meet it in the graded retelling of Hänsel und Gretel, where the witch's oven is central to the story. The text around it is written at your level, so Ofen is likely one of only a few new words on the page, and it recurs several times as the plot develops. After you've met it three times without needing to look it up, ReadNative counts it as known.
Neither experience is wrong. The first is more authentic; the second is more comprehensible. Learners typically need more of the second early on and more of the first later.
Vocabulary review compared
Both apps build review from your lookups, so neither forces you to make flashcards by hand. Readlang's context-cloze flashcards are a genuine strength and are probably better designed as flashcards. ReadNative's review is simpler, and on Android you can export to Anki if you want to manage cards there.
The bigger difference is upstream: what you look up depends on what you read. Reading level-appropriate text tends to mean fewer, more useful lookups, which keeps any review queue manageable. Reading text far above your level can generate a flood of cards, many of which are rare words you won't meet again soon. For more on this, see tap-to-translate without getting dependent.
Who should choose which?
Choose Readlang if:
- You're intermediate or above and already want to read real websites.
- You do most of your reading at a computer.
- You want precise phrase translation and context flashcards.
- Your language isn't among ReadNative's 20.
Choose ReadNative if:
- You're a beginner or lower intermediate and find most real text too hard.
- You want stories written for your level, with a clear next step.
- You're learning a non-Latin script and want romanization alongside glosses.
- You like reading on your phone, including offline.
Using both together
These tools combine naturally. A reasonable plan:
- Use graded books to get your first couple of thousand words. In ReadNative, the free first book in each language, such as Le Tour du monde en 80 jours for French, takes you roughly from A1 to B1.
- Check where you stand with the vocabulary size test (change the language in the URL).
- Before committing to a web article with Readlang, paste it into the text difficulty tool to see whether it's within reach.
- Gradually shift more time to authentic web reading with Readlang as articles become comfortable.
This mirrors the advice in the extensive reading literature, associated with Richard Day, Julian Bamford and Rob Waring among others: read a lot of easy, enjoyable material first, and let difficulty rise as your vocabulary does.

FAQ
Is Readlang or ReadNative better for beginners?
For most beginners, ReadNative is easier to start with, because its books are written for A1 and A2 readers. Readlang works on any text, but beginners usually find authentic web pages too dense to read comfortably, which means constant clicking and less actual reading.
Does ReadNative have a browser extension like Readlang?
No. ReadNative is an app for Android and iOS plus a web app, focused on its graded books and EPUBs you import. If reading arbitrary web pages with click-to-translate is what you need, Readlang is the better tool for that.
Can I import my own texts into ReadNative?
You can import EPUB books, which are translated chapter by chapter so you can check sentences as you read. Readlang is more flexible here, since it accepts web pages and pasted text as well.
Do both apps make flashcards automatically?
Yes. Readlang builds spaced-repetition flashcards from the words and phrases you translate, keeping the original sentence for context. ReadNative puts looked-up words into a spaced-repetition review and lets Android users export them to Anki.
Which languages can I learn with ReadNative?
Twenty, including widely studied ones like Spanish, French and Japanese and less-served ones like Georgian, Armenian, Azerbaijani and Serbian. Each has its own starting page, for example learn German by reading, and the first book in every language is free.
