Show HN: Vocabulary flashcards that use LLMs for definitions and translations

SwiftUI. Cloud Firestore. GPT-4o-mini. Add a word or phrase and get a definition or translation in any language. (Including Klingon). If you add a word like "fork (cutlery)" it will return that definition, and not e.g. a fork in the road, because the LLM understands your original intention. Supports offline review for the cards. The design is based off of the Journals app in iOS. Suggestions and criticism welcome.
