Looks really awesome at first glance, been looking for something like this!
I learned French vocabulary using Anki for a while, but I always found it difficult to remember more abstract words without context or wasn't sure how exactly they are properly used - actually thought about generating an Anki deck with examples with GPT or pulling examples from one of the online dictionaries/wiktionary.
Two questions/comments: Are learned words repeated after some time in some manner? Is it possible to change you username (they seem to be public)?
