The AI response is displayed as text and can also be spoken aloud.

If a built-in word list is deleted, it can be downloaded again from the available word list section.
Downloading Shared Word Lists
When a word list is shared, it appears in the external word list section.
Tap the download button to add the word list to the initial screen of the app.

Flash card study is designed to help you actively recall the meaning of each word.
- A vocabulary word is displayed.
- Select YES if you know the word.
- Select NO if you do not know the word.
- The word is then spoken aloud and you can try to enter its meaning.
- If you cannot remember the meaning, tap the English word to reveal its meaning.
Repeated Listening
The repeated listening feature allows you to listen to vocabulary continuously while studying.
You can select different playback patterns depending on how you want to study.

AI Features
AI Meaning Generation
When you enter a vocabulary word, Hangulday can use AI to generate its meaning automatically.
The language used for the generated meaning follows the language selected in the AI settings. If no language has been selected, the app's default language is used.
AI Conversation
Hangulday provides AI-powered conversation practice for language learners.
When you speak, your voice is converted into text using Apple's speech recognition technology. The resulting text is displayed on screen and used for the AI conversation.
The AI response is displayed as text and is also spoken aloud using Apple's text-to-speech technology.
The original voice recording is not stored by Hangulday. Voice input is temporarily processed for speech recognition and is not saved as a recording file.
