How Flewnt works
You read every chat. In your language. Automatically.
Add Flewnt to any LINE chat the way you add a person. Every message after that is translated the moment it lands, both directions, in 80+ languages. Nobody else in the chat installs anything.
50 free translations. No card required. From $4.50/mo if you keep it.
Two minutes to set up. Then forget about it.
You do this once. After that, every chat you add takes ten seconds. The price never changes.
Add Flewnt on LINE
Under a minute
Tap the button on this page. LINE opens a chat with Flewnt. Flewnt asks which language you want to read in. You answer in one message. Your 50 free translations begin the moment you reply. No card, no form, no trial countdown.
Invite Flewnt to a chat
Ten seconds per chat
Open any LINE chat you are in. Tap the members list. Add Flewnt the same way you add a person. Flewnt posts a short greeting naming the language pair. Everyone in the chat sees translations from then on. They install nothing.
Read everything in your language
Always on
Every message that arrives is translated the moment it is sent. When you reply, your reply is translated into the other person's language. Add as many chats as you like. The condo. The school parents. Work. Your dentist. The price does not change.
What it looks like
One bot message per original. Stacked, clear, in your language.
Someone types in Thai. Flewnt posts the English right underneath. You reply in English. Flewnt posts the Thai for the rest of the chat. The format reads as the sender's name, a small speech bubble icon, then the translation. You always know who said what.
No muted glosses tucked under bubbles. No second app to switch to. The conversation just runs in your language.
Why the translations sound right
Chat is not formal writing.
People drop subjects. Skip particles. Abbreviate. Generic translators read each word in isolation. Flewnt reads the whole message and renders what the person actually meant.
Japanese keigo
お疲れさまです、明日の件、よろしくお願いいたします
Word for word: You are tired. Tomorrow's matter, I beg you.
Flewnt: Thanks for your work today. About tomorrow, looking forward to it.
Japanese keigo uses fixed politeness phrases that mean nothing literally. Flewnt reads the register and renders the actual social meaning, not the surface words.
Thai casual
ขอโทษครับ ผมติดรถ
Word for word: Sorry, I stuck car.
Flewnt: Sorry, stuck in traffic.
Thai chat drops particles and subjects. Flewnt reads the message as a whole, not as isolated words.
Mixed Thai-English
เดี๋ยวส่ง okay ให้นะ
Word for word: Will send okay to you.
Flewnt: I'll send you an okay.
When the writer used the English word "okay" on purpose, Flewnt keeps it. It does not translate words back into their own language.
Thai, Japanese, Traditional Chinese, Korean, Vietnamese, Indonesian, and 80+ more. Flewnt detects each message automatically.
Tone per chat
It translates your landlord differently from your friend.
Type one of three slash commands in a chat. Flewnt adjusts how it writes for that chat from then on. Each chat remembers its own setting.
/casual
For friends and family
Moo-baan chats, the school parents, your partner's family. Relaxed register. Contractions. Particles where the language uses them.
/formal
For work and admin
Landlord, dentist, school office, work chats. Professional register. Full sentences. Keigo or politeness particles where appropriate.
/natural
For everything else
Mixed chats. Flewnt matches whoever spoke last so replies feel like the same conversation, not a different one.
Flewnt is gender-aware in Thai and Japanese. Your replies use the correct gendered particles for the register, even when you write your reply in English.
The only option that does both
Free methods need you. Per-chat bots charge per chat. Flewnt does neither.
The other ways to read a LINE message in your language fall into two groups. The free methods need a copy or screenshot for every single message. The paid bots automate that, but they bill you per chat. Flewnt is per person, so the number of chats does not matter.

Privacy and platform support
Your messages are never stored.
You are trusting a tool with your conversations. We treat that seriously.
Translated and discarded
Flewnt translates each message and discards it. Message text never reaches a database. Language metadata is deleted within 48 hours. Nothing is used to train a model.
Every device LINE runs on
iPhone, Android, iPad, Mac, Windows. Flewnt is a LINE account inside your chat. There is nothing to install, no platform restriction.
Only you install it
The other people in your chat see translations appear automatically. They install nothing, pay nothing, and change no settings.

Common questions
Frequently asked questions.
- Can I translate LINE messages on iPhone?
- Not with LINE's built-in feature. As of early 2026, that is Android only. On iPhone, you can use copy-paste or a translation bot like Flewnt. Full guide for iPhone users.
- Does LINE have a built-in translator?
- Yes, on Android. You long-press a message and tap Translate. It works one message at a time and, as of early 2026, is not available on iOS. Full breakdown of LINE's translator.
- How accurate is Google Translate for LINE messages?
- For formal writing, reasonable. For chat, it falls apart. A Japanese coworker writing お疲れさまです comes out as "you look tired." A Thai friend writing กินข้าวยัง comes out as "have you eaten rice yet." Both are social phrases that mean neither. Flewnt reads them as the greetings they are.
- Do other people in the chat need to install anything?
- No. You add Flewnt to the chat and it works for everyone. Other members do not need to install an app, create an account, or change any settings.
- What happens to my messages?
- Flewnt translates each message and discards it. Message text is not saved to a database. Language metadata is deleted within 48 hours. See our privacy page.
- Can I try before paying?
- Yes. Flewnt includes 50 free translations with no card required. That is enough to test it on your real chats, with your real contacts, for a few days. By the time the 50 run out, you already know whether it works for you. Plans start at $4.50 a month, billed annually. 14-day money-back if you change your mind.
Start free on LINE
You can be in the next conversation in two minutes.
The next message that lands in your chat is in a language you cannot read. With Flewnt, you read it the moment it arrives. You reply. Whoever sent it reads your reply in theirs. The conversation just continues, with you in it.
Without it, you screenshot it. You paste it. You ask someone later what it said. The chat keeps moving while you catch up.
50 free translations. No card. From $4.50/mo. 14-day money-back on paid plans.
Reference
Method-by-method and language detail.
Open any section for a full walkthrough.
Method 1: LINE’s built-in translation
LINE has a built-in translation feature. It works one message at a time. You long-press a message, tap “Translate,” and the translation appears below the original text.
How to use it
- Open the LINE chat containing the message you want to translate.
- Long-press (tap and hold) the message.
- Tap Translate from the menu that appears.
- The translation appears inline, below the original message.
You can change the target language in LINE's settings under Chat > Translation language.
The catch
As of early 2026, this feature only works on Android. If you use an iPhone, the Translate option does not appear in the long-press menu. There is no setting to enable it. It is not available on iOS. Most people in Thailand, Japan, and Taiwan who moved there and use LINE are on iOS. See how to translate LINE messages on iPhone for what does work.
Even on Android, it is manual
Every message requires a separate long-press and tap. In a quiet one-on-one chat, that is manageable. In an active chat where 20 messages arrive while you are making dinner, that means 20 individual taps. There is no “translate all” button. No automatic mode.
Best for one message at a time, on Android. For a deeper look, see Does LINE have a translator?
Method 2: Copy and paste to a translation app
You copy a message from LINE, switch to Google Translate (or DeepL, Papago, or another translation app), paste the text, read the translation, then switch back to LINE.
Seven steps per message
- Open the LINE chat.
- Long-press the message you want to translate.
- Tap Copy.
- Switch to Google Translate (or your preferred translation app).
- Paste the text.
- Read the translation.
- Switch back to LINE.
Accuracy for chat messages
For formal, properly written text, Google Translate is reasonable. A business email in Japanese or a government notice in Thai will produce a usable translation.
For chat messages, accuracy drops. People do not type the way they write formal documents. Thai chat shorthand drops vowels and particles. Japanese chat mixes three scripts with slang and emoji. Chinese chats in Taiwan use Traditional characters, but many translation tools default to Simplified, which introduces subtle errors.
Register collapses entirely. A Japanese coworker writing “お疲れさまです” is not telling you that you look tired. A Thai message like “กินข้าวยัง” is not really asking whether you have eaten rice. These are social phrases. Word-level tools translate the surface and miss the meaning.
The flow problem
Copy-paste breaks your presence in the conversation. While you switch apps, paste, read, and switch back, the chat keeps moving. You also lose context. Translation apps see only the single message you paste. A reply that makes perfect sense in context becomes meaningless when translated alone.
Method 3: Screenshot and Google Lens
Some people screenshot their LINE chat and use Google Lens (or Apple's Live Text on iOS) to read the text in the image.
When it is useful
This method works when you cannot copy the text. If the message is inside an image someone shared, a screenshot and Lens approach can extract and translate it.
The problems
It is slow. Slower than copy-paste. You are adding a screenshot step, opening another app, waiting for text recognition, and then reading a rough translation overlaid on an image.
The translations are rough. Google Lens translates text it detects in an image, but has no context about the conversation. It does not know who is speaking or what the message is replying to.
It does not work well for long chat threads. You get one screen at a time. If the conversation spans multiple screens, you need multiple screenshots and multiple Lens passes.
Languages: what works with what
Thai to English (and English to Thai)
Thai is one of the most commonly translated languages in LINE. Many people who live in Thailand use LINE as their primary chat app. Thai chat drops particles, omits subjects, and runs short forms together without spaces. A message like “ไปไหม” means “are you coming?” but word-level tools render it as “go question”. Polite particles vanish. The same word carries different meanings depending on who is speaking to whom. These patterns are standard in condo chats and work chats, but they produce garbled output in word-level translation tools.
A translation bot that processes full messages handles conversational Thai better than word-by-word tools. More on Thai translation · Thailand country page
Japanese to English (and English to Japanese)
Japanese LINE messages mix three scripts (hiragana, katakana, kanji) with emoji, abbreviations, and varying formality levels. Work chats often use keigo (formal Japanese), which translation tools handle relatively well. Casual chats use colloquial Japanese, which is harder to translate accurately.
The gap between keigo and casual Japanese matters. A message from your manager and a message from your friend might use completely different vocabulary for the same idea. More on Japanese translation · Japan country page
Chinese to English (and English to Chinese)
In LINE, Chinese almost always means Traditional Chinese. LINE's Chinese-speaking user base is concentrated in Taiwan. Most translation tools default to Simplified Chinese (used in mainland China). Running Traditional Chinese through a Simplified pipeline introduces errors: wrong character substitutions and misread idioms.
If you are in Taiwan and using LINE, make sure your translation method handles Traditional Chinese correctly. More on Chinese translation · Taiwan country page
Korean to English (and English to Korean)
Korean LINE usage is smaller than Thai or Japanese. KakaoTalk dominates in South Korea. But Korean speakers living abroad often use LINE, especially in mixed-language households.
Korean uses Hangul, which is phonetically regular. Translation tools generally parse it well. The challenge is formality. Korean has distinct speech levels, and the same sentence in casual vs. polite form carries different social weight.
Other languages
LINE supports messaging in any language. If your chat includes Indonesian, Vietnamese, or another language, a translation bot can handle it. The other methods (built-in, copy-paste, Lens) also work for most languages, with the same limitations described above.
