How to Translate LINE Messages and Write a Reply

For a LINE message you need to understand now, copy the text into a translation app, choose your language, then translate your reply in the other direction before pasting it back. On Android, Google Translate’s Tap to Translate can shorten that process. For an ongoing multilingual group, a third-party LINE translation bot is another option.

I would start with one copied message before adding a bot to a conversation. It lets you check the language and the meaning without changing how everyone else uses the chat. Once translation becomes a repeated task, a group bot may earn its place.

Translate one LINE message on iPhone or Android

1. Copy the message text. Open the conversation, press and hold the text bubble, and choose Copy if that option is available. Copy the complete sentence rather than an unfamiliar word in isolation.
2. Open a text translator. In Google Translate, for example, select the original language or Detect language, then select the language you read.
3. Paste and read the result. Compare names, times and place names with the original. A restaurant name may need to remain unchanged even when the sentence around it is translated.
4. Keep the original available. Return to the LINE chat to check which message you translated and whether an earlier message supplies missing context.

Google’s text translation instructions recommend entering a complete sentence for context. If a short message such as “that one is fine” remains unclear, translate the preceding question too. Guessing what “that one” refers to will not improve just because the translation sounds fluent.

Android shortcut: Tap to Translate

If you use Google Translate regularly, open its settings and enable Tap to Translate. Google documents this as a way to translate copied text from another app. Copy the LINE text, open the Google Translate bubble or shortcut when available, and select the language you want. The exact shortcut can vary by Android version; if it does not appear, open Translate and paste manually.

This works with copyable text. It does not turn a sticker, photo or voice note into text. Google also explains that copied text is sent to Google for translation after you tap Google Translate; copying alone is not the translation step. See its Tap to Translate help for the relevant permission settings.

Write a translated reply without sending the wrong version

Reverse the language direction: write in your language and translate into your contact’s language. Copy the result into LINE’s message box, read the visible draft once, and then send it. Translation and sending are separate actions, which gives you a useful final check.

On Android, Gboard can translate while you type. With Gboard selected as your keyboard, tap the LINE message field, open the keyboard’s features menu, choose Translate, and select the source and target languages. Enter your reply, review the preview, and tap Select to insert the translation into the message field. These are Gboard’s documented Android steps; they translate your outgoing text, not the messages already in the conversation.

Imagine you are arranging a pickup with a host in Thailand. “We arrive at 7” leaves two uncertainties: morning or evening, and which location. I would write “We arrive at the north entrance at 7:00 p.m. on November 8. Is that the correct meeting point?” Keep the actual entrance name from the host’s message. A precise original is easier to act on than a polished translation of an incomplete plan.

When a LINE translation bot makes sense

A bot is useful when several people repeatedly need the same messages translated. It also becomes a participant in the chat, so agree on its use before inviting it. A third-party bot’s language coverage, charges and data handling belong to that service; a LINE account name alone does not establish that LINE operates it.

One documented example is Ligo. Its vendor currently describes this text-chat setup:

1. Use the vendor’s official site to reach its LINE account, or search LINE’s Add friends by ID for @LIGO. Check the account against the vendor’s link before adding it.
2. Add the bot as a friend, then invite it to the group you want translated. Ligo’s setup notes say an existing group should not already contain another bot; check that condition if the invitation fails. Start with a small trial group if the existing conversation contains sensitive material.
3. Set the language pair in that group. Ligo documents #set en th for English and Thai; use its language-code list for another pair.
4. Send an ordinary text message and check whether the translated output appears in the intended languages. Ask another participant to confirm that both sides can follow the exchange.

Ligo documents #off and #on for turning translation off and on for yourself. Check its current limits before relying on it for a busy group. This is a vendor-documented option, not a claim that every LINE account has the same built-in translation setting.

Why the translation instructions you found may not match LINE

Changing LINE’s interface language changes menus, not the meaning of a received message. Likewise, an attractive “LINE Translation” screen online may be a design concept: Katherine Chen’s LINE Translation project explicitly describes a prototype, not a feature-release guide.

If you cannot find a translation switch in your chat, use the copy-and-paste method instead of hunting through unrelated settings. If Copy is missing because the content is an image or audio, ask for the text version or use a tool that explicitly accepts that format. A text keyboard and a text-chat bot do not establish voice-note or LINE-call translation.

For an occasional message, copying is usually enough. For a recurring group conversation, test a documented bot with the people who will use it. In either case, confirm the meeting point, date or other detail that the conversation actually depends on.
