LatenSea: Translate & Learn

You are standing in a restaurant in Osaka and you cannot explain that shrimp will put you in hospital. You are at a massage clinic and cannot say which shoulder. You are holding a menu you cannot read. LatenSea is built for those minutes. It is a translator, a phrasebook and a flashcard app in one, for Spanish, Japanese, French, Korean, Mandarin, German, Italian and Portuguese. SHOW SOMEONE A CARD (Japanese) Fill in a profile once and LatenSea builds cards you hold up: who you are and where you're from, your injuries and the places not to touch, what you can't eat, and an emergency card for medical staff. A food allergy card with the allergen drawn and crossed out is understood before a word is read. 44 point-and-show travel phrases are built in and work with no signal and no account. Your profile never leaves your phone. It is not uploaded, not synced, and not stored on our servers. The cards are assembled on the device from a fixed, human-reviewed Japanese table, and every card shows you in English exactly what the Japanese says. TRANSLATE AND UNDERSTAND Type any phrase and get an instant translation with pronunciation and a word-by-word breakdown, every word glossed in English, with tap-to-hear audio on each line. Translate Spanish, Japanese, French, Korean, Chinese, German, Italian or Portuguese, and understand the grammar rather than just the answer. READ SIGNS AND MENUS Point your camera at a menu, a street sign, a ticket machine or a page. LatenSea reads it, translates it and breaks it down, and you can save any word straight to your vocabulary list or keep the whole sign for later. For Japanese, readings come with furigana and romaji. PRACTICE SPEAKING Chat with an AI conversation partner in the language you are learning. Use Live Translate to speak into your phone and hear it in the other language, or Live Exchange for a two-person conversation across languages. FLASHCARDS AND QUIZZES Turn your saved words into flashcard decks with pictures, readings and example sentences, and into quizzes: multiple choice, listening, or typed answers. Swipe to grade, track what you keep missing, and let the next quiz pick those words for you. LISTEN AND LEARN Generate guided audio lessons: hear a short story all the way through, then walk it back sentence by sentence with translations, grammar notes and key vocabulary. Slow the narrator down while your ear catches up. Lessons you have heard stay on your phone. WORKS WITHOUT SIGNAL Your vocabulary, decks, saved translations and lesson audio are kept on your phone. Save a word or finish a quiz on a plane or a subway and it syncs when you are back. Show cards never needed a connection in the first place.
