まだまだ改良の余地あり

課金してクラウド同期できるようになったはずなのに、端末間で違うフォルダが出るようになりました。フォルダを整理してもアプリを閉じたら整理する前に戻るし、フォルダを削除しても消えないし、これを報告しようとフォームを送ろうとしたらフォームも開けないし、使い勝手があまり良くないなと思いました。今後のアップデートに期待します

検索機能

いつも勉強に使わせていただいてます。1週間前ほどから、単語の検索機能が使えなくなっています。同じアプリを使用している友人も同じことが起こっていました。とても使いやすいアプリなので、ぜひ修正して欲しいです。

FAQ

What does AITAN do?

AITAN is an AI-powered English vocabulary app that helps users create vocabulary flashcards. It uses AI to instantly generate word origins, example sentences, synonyms, and antonyms for any word you input. The app also incorporates a spaced repetition system based on the forgetting curve to optimize word memorization.

How does the AI help create vocabulary cards?

With a single tap, you can input an English word, and the AI will automatically generate comprehensive information for it. This includes its etymology (word origin), relevant example sentences, and a list of synonyms and antonyms, eliminating the need for manual research and creation.

How does AITAN help with memorization?

The app is designed to maximize word retention by leveraging the forgetting curve. It intelligently schedules review sessions for words just before you're likely to forget them, presenting them as review cards at optimal intervals to reinforce learning.

Is AITAN free to use?

The application is free to download and use, but it offers in-app purchases. This means that while core functionalities are available for free, certain advanced features or content might require a purchase.

Who is AITAN for?

This app is ideal for English language learners who want a more efficient way to build and study vocabulary. It's particularly beneficial for students, travelers, or anyone looking to expand their English word knowledge and improve long-term retention.
