About this app

Eitan is an AI-powered English learning app designed for efficient memorization of English vocabulary. The AI ​​creates natural-sounding example sentences from your word list, allowing you to check the meaning and usage of words within real-world contexts. Read the example sentences, answer questions, and review the AI's scoring results and explanations to efficiently learn the words you've already memorized and those you're still unsure of.

Suitable for school tests (elementary, middle, high school, and university), entrance exam preparation, TOEIC preparation, Eiken (English proficiency test), TOEFL, and IELTS preparation.

Main Features

* AI-powered example sentence creation from word list: Create example sentences for English learning based on your desired word list.

* Example sentence-based learning: Learn by considering the meaning of words within real-world English sentences, rather than just in isolation.

* Scoring and explanations: Review correct/incorrect answers and explanations after answering. This helps you understand not only the meaning of individual words but also the entire example sentence.

* Learning progress management: Review your progress by viewing your status (unlearned, partially remembered, mastered). The in-app dictionary contains over 200,000 words.


• Share with friends
You can study with your own created materials, publicly available materials, and with friends or anyone around the world.

Recommended for people who:

• Don't want to just memorize English vocabulary by rote

• Want to learn how to use words within many example sentences


• Want to gain usable knowledge by answering with free input, something that multiple-choice answers can't do


• Want to learn with example sentences that match their level and purpose



Want to streamline the creation of English learning materials using AI



Want to review while organizing the words they've learned and the words they struggle with


Eitan aims to provide a learning experience that brings you closer to "being able to use" English vocabulary, rather than just "knowing" it.
