LingQ relies on user generated hints to fuel their popular word meanings. This means that for more commonly studied languages there are enormous amounts of translations and examples. For less commonly studied languages you may only have the default translation and a button to check the dictionary. Someone with a bit of know how just needs to import the entire wiktionary for that language and have it pre-populated with definitions. They are looking to improve this with their GPT word hints and GPT contextual word translations which are available on the iOS app.
