Tango - 検索とメモと学習 覚えたい言葉を単語帳へ 　

When you come across an unfamiliar word while reading or browsing the web, wouldn't it be convenient to automatically look it up and save it to your vocabulary list? Tango is an AI-powered vocabulary learning app that makes that dream a reality.

■ Instant word search anywhere
Tango's greatest feature is its "Search in Tango" feature. Simply select text in any app—browser, e-book, social media, etc.—and tap "Search in Tango." The search runs in the background, even without opening the app, and you'll receive a notification with the results. Look up any word you're interested in right away and add it to your deck with a single tap.

■ Abundant AI-generated learning content
For each word you search, AI automatically generates the following information:

Easy-to-understand definitions
Phonetic symbols
Multiple actual usage examples

Enhance your learning with practical, memorable content that goes beyond dictionary usage.

■ Customizable decks
You can organize your words into decks (vocabulary lists). Create decks for specific purposes, such as "TOEIC Preparation," "Business English," or "Everyday Conversation," and manage them efficiently. Set daily learning goals for each deck and see your progress at a glance.

■ Scientifically Based Spaced Repetition Learning
Tango's flashcard feature uses a spaced repetition system based on the SM-2 algorithm. It schedules review sessions at optimal times based on your memory.

Simply view words and rate them on a four-point scale: "Forgot," "Difficult," "Remembered," or "Easy." Difficult words are presented frequently, while easier words are spaced apart for efficient memorization.

■ In-Session Optimization
The same word will never appear multiple times in the same session. Words you get wrong will be retested after you've reviewed several other words. This ensures true retention, without relying on short-term memory.

■ Search History
All previously searched words are saved in your search history. You can review and add words you haven't yet added to your deck.

■ Multilingual Support
Search for and learn words in a variety of languages, not just English. The interface is available in both Japanese and English, so you can use it in your preferred language.

■ Simple and Intuitive Design
The essential functions are packed into a simple UI. Search, manage decks, study flashcards, and check your history—all intuitively.
