💡 In one line: ArirangX is a video call and chat app for iPhone and Android that turns what the other person says into live captions in your language — so two people who don't share a language can simply talk, face to face.

Most translation apps make you take turns: speak, wait, hand the phone over, read, repeat. That is fine for asking the way to the station. It is not how you get to know someone. ArirangX was built for the second case — a real conversation on video, where each person speaks their own language and reads the other in theirs, while they are still talking.

What is ArirangX?

ArirangX (아리랑엑스) is a social video call and chat app made by HyperBabel, named after Arirang, Korea's best-loved folk song. It puts the three things you need to talk across a language barrier in one app:

1. Live interpreted captions on 1:1 video calls — the other person's words appear in your language while they are speaking.
2. Chats that translate themselves — you write in your language; they read it in theirs.
3. Voice input that sends a translated message — say it out loud and it goes out as text in the other person's language.

Around that core sits everything that makes a social app worth opening every day: people who share your interests, a community timeline called Madang, gifts, an AI voice interpreter for face-to-face conversations and a photo translator for menus and signs.

The app itself speaks English, Korean, Japanese, Chinese (Simplified and Traditional), Spanish, French, German, Portuguese, Russian, Arabic, Italian, Turkish, Thai, Vietnamese, Malay, Indonesian and Hindi.

How a live-interpreted video call works

1. Start a 1:1 video call from a chat or from someone's profile.
2. Just talk. Each phone listens only to its own microphone, so your speech is recognized on your side and theirs on their side — no crosstalk between the two voices.
3. Read the conversation as it happens. Your own words appear in white so you can check you were heard correctly. The other person's words appear next to their video in two lines — what they actually said, and the translation in your language.
4. Captions switch on by themselves when the two of you speak different languages, and the CC button turns them on or off at any time.
5. Keep the conversation. When you hang up, the captions are saved in your chat as a transcript — handy for a phone number, a place name or the word you wanted to learn.

The details that matter in daily use:

• Captions appear while the other person is still speaking, not after they finish. That is the difference between interpretation and translation — you can react, smile and answer at the pace of a normal conversation.
• Incoming calls ring on the lock screen like a regular phone call, and a call keeps running when you switch to another app.
• Free beauty filters on every call. Try them on your own camera in the K-Beauty corner before you call.

Chat that translates itself

• Automatic translation — messages arrive in your language, so both of you write naturally and nobody has to switch languages.
• Voice input — tap the mic, speak, and ArirangX sends what you said as a translated message.
• Listen to original — have a message read aloud in its original language to hear how a Korean, Spanish or Japanese sentence really sounds.
• Photos, videos and albums — send up to 10 photos as a single album, plus videos, voice messages and your location.
• Emoticons and reactions — 64 free animated emoticons, 3D sticker packs you unlock once with Stars and keep forever, and quick reactions to any message.
• Link previews — shared links open into a preview card.
• Chat with yourself — a private room for notes and links you want to keep.

Voice interpreter and photo translator

The Interpreter tab brings the same AI into real life, away from video calls:

• Voice interpreter — speak and watch captions and the translation appear as you talk. In face-to-face mode you put the phone between you and the other person: the top half of the screen faces them, so each of you reads the other's words. Only one phone is needed — perfect for a shop counter, a taxi or meeting a friend's family.
• Photo translator — snap a menu, a sign, a cosmetics label or a notice and get the translation plus a short explanation, then share it to a chat, post it to Madang or send it to other apps. AI translations can be wrong, so for allergies or health matters always double-check with staff.
• K-Beauty — preview the beauty filters on your own camera.

ArirangX also includes speaking practice: pick the language you are learning, read a sentence aloud, and see how closely what the AI heard matches it — a quick daily drill for learners (it measures recognition, not a pronunciation score).

Meet people who share your interests

• People — browse All, New, by Interests or on a Map, filter by interests and follow the people you like. Profiles show each person's local time, so you know when it is a good moment to call.
• Madang — named after the open courtyard at the heart of a traditional Korean home, Madang is ArirangX's timeline for posts, replies, photos and videos, with All and Following views and posts you can read in your language.
• Friends who viewed me — see who stopped by your profile.
• Profile link and digital card — share your profile as a link or a QR code.
• Gifts and Stars — send a coffee, a rose, a gift box, a crown or a rocket with Stars, ArirangX's in-app currency. Gifts you receive turn into free translated call time.
• Seasonal backdrops and themes — dress your profile in autumn leaves or winter snow, and switch between light and dark mode.

Free, with VIP when you want more

• ArirangX is free to download, and every member gets a free daily allowance of video calls, live captions and chat translation.
• New members get their first seven days with the daily limits lifted (fair-use limits still apply).
• VIP (monthly or yearly) removes the daily limits within fair use and adds a VIP badge. One-day and seven-day VIP passes can also be redeemed with Stars.

Safety by design

• A real profile photo is required before you can call or message — one you uploaded yourself.
• Report and block users, messages, posts and rooms. Blocked users cannot message or call you, and posts reported by several people are hidden automatically.
• Muted words keep words you never want to see out of your feed.
• One phone per account at a time, so your account cannot quietly run on a second phone.
• Consent first — ArirangX asks before speech recognition is used for the first time.
• Privacy-minded ads — only non-personalized ads, and no tracking across other apps.
• Delete your account from inside the app whenever you want.

Who ArirangX is for

• Making friends across borders — K-culture fans talking with people in Korea, and Koreans talking with friends abroad.
• Language learners — real conversations with native speakers, with the original and the translation side by side.
• Families and couples — staying close with relatives or a partner who speaks a different language.
• Travellers — the voice interpreter and photo translator in your pocket for menus, signs and shop counters.

Built on HyperBabel

ArirangX runs on the same real-time platform HyperBabel offers to developers as HyperAPI — chat, video, live streaming, AI translation and speech translation behind one API key. If you want live-interpreted calls inside your own product, start with the HyperAPI docs or read how translation runs inside the message pipeline.
