LINE Translation Bot Guide: Compare Tools & Set Up in Minutes
What Is a LINE Translation Bot and Why Do You Need One?
A LINE translation bot is an AI-powered chatbot that automatically translates messages inside LINE conversations. Instead of copying text into Google Translate and pasting it back, a translator for LINE sits inside your chat and can translate LINE messages in real time — so everyone in the conversation can read messages in their own language.
If you manage a multilingual team, run a business with international clients, or simply chat with friends who speak a different language, a LINE translator saves you hours of manual translation every week. And if you're working in industries like construction, hospitality, or manufacturing in Asia — where LINE is the default communication tool — it's practically essential.

LINE Translation Tools Compared: Which One Is Right for You?
Not all LINE translation options are created equal. Here's how the main tools stack up:
LINE's Built-In Translation
LINE has a native translation feature — you can right-click (or long-press) any message and select "Translate." It supports about 15 languages including English, Chinese, Japanese, Korean, Thai, Vietnamese, and Indonesian.
Pros: Built-in, no setup required, free.
Cons: Manual — you have to translate messages one at a time. No automatic group translation. No voice message support.
Third-Party Translation Bots
These are chatbots you add to LINE that automatically translate every message in a conversation or group.

| Group chat translation | ✓ Automatic for all members | ✓ Yes | △ Limited |
| Multi-language groups (3+ languages) | ✓ Up to 5 simultaneously | △ Limited (max 5) | ✗ No |

Browser Extensions & Automation Tools
- Chrome extensions (e.g., LINE App Translator Bot): Translate LINE Web messages in your browser. Limited to desktop, don't work in the LINE mobile app.
- Make.com / Zapier automations: Connect LINE to Google Translate API for automated workflows. Requires technical setup and API costs.
Bottom line: If you need automatic group translation — especially for Southeast Asian languages or voice messages — a dedicated LINE translator bot like Echonora is your best option, with the widest language support (100+) and the only free-tier voice translation in group chats. AutoTranslate is worth considering if you only need 33 languages and are willing to pay for voice features. LINE's built-in feature works for occasional one-off translations, and browser extensions are fine for desktop-only use.
How to Set Up a LINE Translation Bot (Step-by-Step)
LINE translation bot setup takes less than 5 minutes. Here's how:
Step 1: Add the Translation Bot as a Friend
- Open LINE and go to the search bar
- Search for the bot name (e.g., "Echonora") or scan the QR code from the bot's website
- Tap Add Friend
- You'll receive a welcome message confirming the bot is active
Step 2: Invite the Bot to a Group Chat
- Open the LINE group where you want translation
- Tap the menu (≡) → Invite
- Find the translation bot in your friend list and invite it
- The bot will send a setup message in the group
Step 3: Configure Your Languages
- For Echonora: Type
@Echonora English, Vietnamese(or whatever languages your group needs) - For Ligo: Type
#set en vi(using language codes)
That's it. Every message sent in the group will now be automatically translated for all members.

Multi-Language Group Chat Translation
The real power of a LINE translation bot shows up in LINE group chat translation with multiple languages. Imagine a construction site group with a Taiwanese manager (Chinese), Vietnamese workers, and a Thai supervisor — all in one LINE group.
How It Works
With Echonora, each person types in their own language. The bot detects the language automatically and translates every message into every other language in the group. So:
- The manager types in Chinese → Vietnamese workers see Vietnamese, Thai supervisor sees Thai
- A Vietnamese worker replies → Manager sees Chinese, supervisor sees Thai
- Everyone communicates naturally without switching apps or waiting for translations
Setting Up Multi-Language Groups
- Invite Echonora to the group
- Set all required languages (e.g.,
@Echonora English, Chinese, Vietnamese, Thai) - Each member writes in their preferred language — translations happen automatically
This is something LINE's built-in translation simply cannot do. It only translates one message at a time, for one language pair.

Voice Message Translation on LINE
This is the feature most people don't know exists. In many workplaces — construction sites, kitchens, factories — people send voice messages on LINE because typing is impractical. But what happens when your Vietnamese worker sends a voice message and you don't speak Vietnamese?
How Voice Translation Works
Echonora can:
- Receive the voice message in LINE
- Convert the speech to text (speech-to-text)
- Translate the text into the group's other languages
- Display the translated text in the chat
So a Thai worker sends a voice note in Thai → you see the translated English text in the chat. No extra apps, no manual steps.
Echonora supports voice translation across 100+ languages directly in group chats. AutoTranslate offers voice translation in its premium tier, but is limited to 33 languages. Ligo, LINE's built-in features, and browser extensions don't support voice translation at all.

Frequently Asked Questions
Is there a free LINE translation bot?
Yes. Both Echonora and Ligo offer free tiers. LINE also has a built-in translation feature (right-click → Translate) that's completely free but limited to manual, one-message-at-a-time translation. For automatic group chat translation, Echonora's free plan is the easiest starting point.
How accurate are LINE translation bots?
Modern LINE translation bots use AI models similar to Google Translate and DeepL. For common language pairs (English ↔ Chinese, English ↔ Vietnamese), accuracy is generally high for everyday conversation. Technical jargon, slang, and very short messages may occasionally mistranslate. Echonora averages about 2 seconds per translation with strong accuracy across Southeast Asian languages.
Can I use multiple translation bots in one LINE group?
No. Only one translation bot should be active in a group at a time. Multiple bots will conflict and produce duplicate or incorrect translations.
What languages do LINE translation bots support?
Echonora and Ligo both support 100+ languages. The most commonly used pairs include English, Chinese (Traditional and Simplified), Vietnamese, Thai, Indonesian, Japanese, Korean, Spanish, and Filipino. LINE's built-in translation supports about 15 languages.
Do translation bots store my messages?
Reputable bots like Echonora process messages for translation and do not permanently store your chat history. Temporary diagnostic logs may be retained for up to 30 days for troubleshooting and abuse detection, then automatically deleted or anonymised. Always check the privacy policy of any bot you add to sensitive work conversations.
Can translation bots translate images or documents?
Not directly. LINE translation bots work with text messages and (in Echonora's case) voice messages. For images containing text, use your phone's built-in text recognition first, then paste the extracted text into the chat.
