Flashcards for the language you’re learning, in the app you already use
NextLang is an AI flashcard generator for language learners: pick your pair and your level (A1 to C1) and get a native .apkg or .mochi that imports in one click with the pronunciation audio already inside it, or a set ready to paste into Quizlet.
No formatting, no copy-paste gymnastics. You bring the words, NextLang does the rest.

The part everyone else leaves to you
Built around how language learners actually study, not a generic flashcard maker bolted onto an AI.
Native .apkg and .mochi, audio inside
Anki and Mochi sets download as the app's own package with the pronunciation mp3 files packed in, so the deck keeps speaking after it leaves NextLang: no add-on, no Mochi Pro, no external service. Double-click and it opens with fields, tags and sound already in place. Word audio is free on every account and never costs a credit.
Import-ready, not almost-ready
Every file lands in the exact shape your platform expects, with accents, quotes and separators escaped correctly. Drop it in and study instead of fixing columns.
Study before you import
Flip through a new set on the page the second it exists, keyboard-first, with a focus mode. Save the words worth keeping straight from the card face.
Your reading becomes your word list
Paste an article or drop in an episode's subtitles and get back the vocabulary at your CEFR level, each word in its dictionary form with the sentence you actually met it in.
Spaced repetition that is yours
Saved words come back after 1, 3, 7 and 21 days. Learned is earned by getting a word right four reviews running, never toggled, and learned words still return for maintenance.
Pay for output, not for time
Credits, not a subscription: one credit per set whether it holds 5 cards or 30, 5 free credits that refill every 30 days. Studying, saving words and re-downloading never cost anything.
How NextLang compares
Other generators make cards. These are the differences that decide whether the deck you get is one you can actually study from.

Learning guides
Expert strategies and proven techniques to get the most out of every deck you build.
Tell us and you are paid for it: we refund the credit that generated the deck and add 3 more on top, for up to 20 reports a month. Broken formatting, the wrong language, a duplicate inside one deck or a card clearly off the level you asked for count automatically; a translation you would not have chosen we read ourselves and tell you which way we called it. Email support@nextlang.co with the subject "Card report" and include the link to the deck. What counts as a bad card
What is NextLang?
NextLang is an AI flashcard generator for language learners that exports native Anki .apkg and Mochi .mochi decks with pronunciation audio embedded, across 20 languages at CEFR levels A1 to C1, plus ready-to-paste sets for Quizlet and Brainscape. You give it vocabulary, an article, a photo or a subtitle file; it gives you back a deck you can import in one click, edit before exporting, and study on the site.
How does NextLang work?
Choose your preferred flashcard platform (Quizlet, Anki, Mochi or Brainscape), pick the language you are learning and the language you want translations in, describe what to cover, and specify how many cards you want. Our AI generates accurate translations and formats them perfectly for your chosen platform.
Which platforms does NextLang support?
NextLang supports four major flashcard platforms: Anki (native .apkg package plus CSV/TSV), Mochi (native .mochi package plus CSV or Markdown), Quizlet (tab/semicolon separated text), and Brainscape (CSV import). You can generate content for any or all of these platforms.
What languages are supported?
NextLang supports a wide range of languages including English, Spanish, French, German, Italian, Russian, Polish, Portuguese, Ukrainian, Japanese, Korean, Chinese, Hindi, Arabic, Turkish, and many more. You can create translation decks between any supported language pairs.
How many flashcards can I generate?
You can generate between 5 and 30 cards in one generation, and each generation costs 1 credit. A saved deck can then be grown in the same steps, one credit each, up to 200 cards in total.
Do I need to pay to get started?
No! Every account gets 5 free credits, and they refill to 5 every 30 days. No credit card required. Simply sign up and start generating flashcards immediately.
How accurate are the translations?
A language card is the easy case for accuracy: unlike a card asserting a fact you would need expertise to verify, a translation can be checked in a dictionary in seconds, and at any level you can usually spot an unnatural example yourself. What we can guarantee outright is the mechanical side, because the app builds the file instead of asking the model to format it. We publish what our own testing measured. How we keep cards accurate
Do the flashcards come with pronunciation audio?
Yes, and no add-on or extra service is involved. Every card is voiced with a natural neural voice in the language you are learning, across all 20 supported languages, and the mp3 files are packed inside the Anki .apkg and the Mochi .mochi package itself, so the deck keeps speaking after it leaves NextLang. Mochi Pro is not needed for it. Word audio is free on every account, audio for the example sentences comes with premium, and neither costs a credit. A toggle in the download menu turns audio off if you want a lighter file.
Can I use NextLang on mobile devices?
Yes! NextLang is a web-based platform that works on any device with a browser. Once you generate and download your flashcards, you can import them into your chosen platform's mobile app (AnkiMobile, Quizlet app, Mochi app, or Brainscape app) to study on the go.
What file formats does NextLang generate?
The file format depends on your chosen platform: Anki gives you a native .apkg package (plus CSV/TSV), Mochi gives you a native .mochi package (plus CSV or Markdown), Quizlet uses tab/semicolon separated text, and Brainscape uses standard CSV. Native packages import in one click with fields and tags intact; all formats are ready for direct import into their respective platforms.
Can I customize the generated flashcards?
Yes! Once imported into your chosen platform, you can fully customize the flashcards. Add images, modify text, adjust card templates, and organize them into decks however you prefer. Pronunciation audio is already generated for you and rides inside the Anki .apkg and Mochi .mochi packages. NextLang provides the foundation - you make it your own.
Can I share my flashcards?
Yes. Open your deck and hit 'Publish to gallery' (a Premium feature, and the deck needs at least 10 cards). You get a public link like nextlang.co/decks/your-deck-name that anyone can open without an account: they can browse every card and export it as .apkg, .mochi, or copy-paste text, with the audio embedded in those files when they are signed in. Your deck also appears in the public gallery at /decks. While a deck is public it is locked for editing, so make it private again if you want to change it, and you can unpublish at any time. Unpublished results stay private to you.
