Create AI friends
Customise each friend's personality, voice, and chat style. Make them patient, dramatic, strict, soft, funny, or whatever gets you replying.
Give them personalities and voices, chat naturally, save words you actually want, then practise them in calls, lessons, and your Wordbank.
The practice gap
Not because you know nothing. You recognise the words and understand the sentence. But replying is a different skill. IntroBird gives you AI friends to practise that moment safely.

Customise each friend's personality, voice, and chat style. Make them patient, dramatic, strict, soft, funny, or whatever gets you replying.

Text like a normal chat. Read Korean in context, save useful words from the message, and keep going without turning everything into homework.

When typing feels too safe, pick up a call. If your brain buffers, ask in English and learn how to answer in Korean.

See a useful Korean word or phrase mid-chat? Save it before it disappears into the "wait, I knew this yesterday" pile.


Your Wordbank is where saved words get a second life. Practise them with AI friends, use them in lessons, and meet them again until they stop feeling random.
