NGSL Builder 日本語版 is a user-friendly application designed to assist learners and teachers in effectively using the highly acclaimed New General Service List (NGSL). The app features a simple tool to download, email, and combine NGSL word lists, as well as a learning tool to quickly and efficiently study and track progress. Users can also email their progress to themselves or their teachers.

The app provides word definitions written in simple English, some with accompanying audio pronunciations by native English speakers, as well as Japanese translations of the words.

Intelligent Flashcards:

NGSL Builder 日本語版 also includes an Intelligent Word List Maker and an Intelligent Flashcard System.

With the Intelligent Word List Maker, users can quickly and efficiently select unfamiliar words within the flashcard system to study. Rather than having to go through all the lists at once, the Intelligent Word List Maker guides users to go through the lists in order of frequency and allows for gradual addition of words as needed or when time permits.

Based on the scientifically documented "spaced repetition," the Intelligent Flashcard System systematically and efficiently helps users review words multiple times over a one-month period. This allows for more focused attention on challenging words.

The NGSL is an open source free access wordlist and is used with permission.
