AI-powered English wordbook

What it does

This app is an AI-powered English wordbook. If you’re an English learner and sometimes encounter unknown words, this app will greatly help with your learning.

The basic features are SEARCHING, CHECKING EXAMPLE SENTENCES, and REVIEWING. You can search for unknown words, check example sentences in your familiar language, and then review the words after some time.

We used the Gemini API for three purposes:

First, for word suggestions. We primarily use the Datamuse API for searching and suggesting words because it is free and fast. However, if you are Japanese and don’t know a word, this app detects Japanese and suggests English words that match the Japanese words via the Gemini API.

Second, for example sentence translations. If you are Korean, you can see translations of example sentences into Korean through the Gemini API. This app supports a wide range of languages.

Lastly, for reviewing your own sentences. After saving words, you can review them by creating your own sentences. This approach is called “Active Learning.” Creating your own sentences makes your language learning more efficient. At this stage, Gemini will review your sentences and provide feedback on their correctness. If a sentence is incorrect, Gemini will suggest how to fix it.

That’s all. Thank you very much.
