Dictionaries

Word meanings come from one of two dictionaries, depending on the language.

Wiktionary
Definitions for most languages, from the English Wiktionary. For German, a copy kept on our server, from the kaikki.org extract.
Text available under CC BY-SA 4.0.
CC-CEDICT
Chinese to English, with pinyin, which is what lets a click on one character answer for the whole word.

Ready decks

The ready flashcard decks (Flashcards, Add words) are sorted by level and topic. Which words belong to a level follows the word lists the Goethe-Institut publishes for its A1, A2 and B1 exams: we take the word, its article and its plural, and nothing else. The topics are our own sorting. Each meaning is the first sense in Wiktionary, cut short, and each example sentence with its English is from Tatoeba; both are credited on this page. The decks are not made, checked or endorsed by the Goethe-Institut.

The Goethe-Institut publishes no list for B2. The B2 decks are our own choice: common German words that its A1 to B1 lists do not have, sorted by us into the same topics. Our B2 is no exam's.

Some decks have a short episode to listen to (Listen). Its story is written by us with an AI assistant, using only words of the deck and of its level's word list, and it is read by computer voices (Microsoft Azure), not by people.

Example sentences

When you add a word by hand, the example sentences offered come from Tatoeba, a collection of sentences written and translated by volunteers.

Tatoeba
Sentences with English translations, for most languages.
Used under CC BY 2.0 FR.

When Wiktionary has no entry for a word, usually a long German compound, the meaning shown is a machine translation from MyMemory, and the card says so.

Words you save carry the same credit into the file when you export them, so it travels with the meanings rather than staying behind on the site.

Word frequency

How common a German word is, which the report uses to estimate the level of a video and of your vocabulary, comes from a list counted over film and TV subtitles.

Reading an Anki deck

A deck you add is read in your browser. Decks written by a recent Anki are compressed, and a small reader unpacks them.

Speech and language services

Some features hand a request to another company's service. What is sent, and when, is in the privacy policy; here is who they are.

Microsoft Azure Speech
Pronunciation assessment: the scores for your sounds when you shadow a line or check your pronunciation.
AI language and speech models
Used for Paraphrase, in different tools and layers: the guide map of a part, the check of your version against the ideas and the grammar, and your voice turned into text.
Your device's own voice
Reads Easy and Medium stories and the word speakers aloud, through your browser's speech synthesis. Nothing is sent for that.

Stories

The videos, titles and pictures on the story cards belong to the channels that made them. Hard plays the video itself in YouTube's own player; Easy and Medium are machine rewrites of the video's transcript, for reading.
