126 languages
Natural, contextual translation across every major world language — and a chat runs as many of them at once as it needs, with no cap on any plan.
PlumiBot translates voice, images and text across 126 languages — without ever leaving LINE. It reads the room for context, keeps replies clean, and lets everyone just talk.
Translation, voice, images, karaoke and games — built from the ground up for mixed-language group chats.
Natural, contextual translation across every major world language — and a chat runs as many of them at once as it needs, with no cap on any plan.
It reads recent chat to settle short or ambiguous messages, then hands back just the clean translation — no tags or commentary.
Long or forwarded messages get auto-summarized before translation — no walls of text.
Send a LINE voice note and get an instant transcript plus translation; long clips are summarized.
Snap a menu, sign or document for a clean translation. Text-free photos — selfies, food, scenery — are silently ignored.
Name a song and PlumiBot finds it, then writes the pronunciation under every line — pinyin with tone marks, Hepburn romaji, Revised Romanization, Jyutping. Enough to hold your own at KTV in a language you don't read.
!sing meaning
explains the song you just pulled up — the story it tells, and the lines that don't survive a literal translation. Karaoke mode also reads a photo of the screen you're singing from.
Word Chain and Translation Duel, broadcast in every group language with leaderboards and bonus tokens for winners.
!digest 3h or !digest 1d summarizes recent chat, up to 7 days back.
See top translators and active languages at a glance, and earn bonus tokens when friends join with your code.

Wherever people who don't share a language share a chat, PlumiBot keeps everyone on the same page.
Plan dinners, share news, and keep grandparents in the loop across borders — everyone reads and replies in their own language.
Standups, handovers and watercooler chat in one LINE group. Voice notes get transcribed; menus, docs and screenshots get OCR'd and translated.
Pick up real, idiomatic phrasing from everyday chat — then put it to the test in Word Chain and Translation Duel.
One bot, the whole cabinet — every one of them with the same natural, idiomatic translation.
Add PlumiBot, drop it into a group, breeze through a 15-second setup, and you're translating. Then upgrade and manage your plan whenever you're ready.
Scan the QR code inside LINE, or tap the button under it if you're already on your phone. Either way PlumiBot is added as a friend — that's the whole install, nothing to download.
Open any LINE group, tap Invite, and pick PlumiBot. It starts translating the moment it joins — or chat one-on-one in a DM instead.
PlumiBot sends you a 15-second DM to set your name and the language it talks to you in. In a hurry? Tap !skip. Change your mind later with !setlang fr (or any language code).
Just chat normally. Send a voice note to get it transcribed and translated, snap a photo of a menu or sign for clean OCR, and type !help any time for a tappable menu of everything.

Every plan spends one clear currency — tokens — across every feature. You pay for what you actually use: a one-line message is genuinely cheap, and a photo of a menu costs what a photo of a menu costs.
Tokens are how AI measures text length. A short message is ~50 tokens, a normal sentence is ~200 tokens, and a long paragraph is ~1,000 tokens. A translation spends tokens on both sides — the message in and the translation out — so a normal message costs ~350 in total.
Because a 5-word message and a 500-word document aren't the same. A token budget charges you for the size of what you send, not the number of times you send it — and a token costs the same whether it went through chat, a voice note or a photo. Pay as you go spends the same tokens at NT$60 per million, with no monthly fee.
The honest trade: if most of what you send is photos or long voice notes, an allowance goes down several times faster than it does on chat. That is the cost being passed on rather than averaged across everybody.
| Rule of thumb | Token cost |
|---|---|
| Text translation | ~350 |
| Voice note, a few seconds | ~500 |
| Voice note, a minute | ~4,000 |
| Photo — sign, receipt, menu | ~3,000–8,500 |
| Karaoke song | ~2,000–5,000 |
| Daily digest | ~800–2,000 |
| Game messages | ~200–400 |
Prices in NT$ · no card for the free tier · monthly tokens reset on the 1st, PAYG credits never expire.
Free covers the thing most groups came for: chat translation in every language, plus games, digest and stats. Reading voice notes, photos and shared links — or fetching a whole song — costs several times more to run, so those live on the paid plans, along with a much bigger token budget.

Every plan translates chat on the same model, free ones included — paying more should buy you more translation, not a better sentence. The larger model is reserved for what genuinely needs it: reading voice notes, photos and shared links. We keep swapping in better models as they ship, and your plan follows along at no extra cost.
Need more than the standard plans? We build tailored solutions — higher quotas, custom languages, dedicated support, white-label, SLAs and on-premise.

Beyond that we hold on to a message for one reason: if a translation trips our automatic quality check, it's kept so a human can see what went wrong and fix it. Ones that pass are deleted as soon as they're checked.

PlumiBot was born from a simple desire: to make relationships easier across languages, cultures, and borders.
Long before apps and instant messages, carrier pigeons were the world's most trusted messengers — crossing borders and braving storms to reach people who had no other way to connect. Plumi carries on that tradition in a modern form: swift, reliable, and always bridging the distance between languages and cultures.
Swift. Loyal. Always delivering.
The softest feather of a bird. Representing lightness, agility, and the gentle touch of a natural translation.
The quill used for writing. Representing the art of communication and the permanence of shared understanding.
Our goal is to make relationships easier around the world — not just through text, but through voice and images that make communication feel effortless across every language.
Every feature answers one question: does this make it easier for people to connect?
Translation isn't just swapping words — it's carrying humor, warmth and tradition across.
New platforms, deeper lore and seasonal celebrations — PlumiBot grows with its people.
Every update that changed something you can see, from V1 to today. Releases that only touched the machinery we run ourselves carry their own version numbers and aren't listed here, so the newest version below may sit behind the one in the footer.
A photo of a receipt gets read out in four languages. A voice note arrives in the middle of a meeting. Someone starts a word game in the work group. Until now the only way to stop any of that was to remove the bot. Type !app, open the group's page, and there are now switches: photos, voice notes, karaoke and games, each one on or off for that chat.
!sing where karaoke is off and you do get an answer, because you asked for it by name: the chat switched it off, not that you need a bigger plan.Commands keep working while translation is paused, so a chat can always lift its own pause — !app opens the page that turns it back on.
Changing anything about your groups used to mean leaving the conversation: ask for a sign-in link, wait for it to arrive, open a browser, sign in. Type !app and the same dashboard now opens as a screen inside LINE — already signed in, because LINE knows who you are.
!app works in any chat and needs no link, no browser and no password. Send it in a group and it opens straight onto that group's page.!lang add — and, exactly as in the chat, any member of the group can do it, not only whoever pays.PlumiBot will not show up in LINE's own list of apps: being listed there needs a certified provider, which is not something Taiwan grants yet. Reach it with !app. Nothing about the ordinary website changed — !login and plumibot.com work exactly as they did.
Type 食飽未 in a Taiwanese group and PlumiBot used to read it as Mandarin, decide no translation was needed, and say nothing — leaving everyone who does not speak Taiwanese looking at a message they could not read. Taiwanese Hokkien and Hakka are now languages in their own right, and a message in either one gets translated like any other.
nan and hak, or Taigi, Hokkien, Hakka, 客語.Voice notes in a chat with 臺語 or 客家話 switched on are still transcribed as Chinese. Dialect speech recognition fails in a way you cannot see — it reads fluently and changes the meaning — so it is not something we will ship until it is right. These two also need a stronger model, so one Taiwanese or Hakka message draws about 1,250 tokens where an ordinary message draws 350 — roughly 3,100 of them a month on Personal Pro, or 9,500 shared on Group Pro.
Finding the lyrics to a song is easy. Finding them written in letters you can actually sing from is not — and that is the part that decides whether you take the microphone. Name a song and PlumiBot now looks it up and writes the pronunciation under every line.
!sing plus a song name returns the lyrics with the sound under each line — pinyin with tone marks, Hepburn romaji, Revised Romanization or Jyutping.!sing meaning explains the song you just pulled up — what it is about, and the lines a literal translation loses.Karaoke is a paid feature — one song costs several times what a translated message does. Everything else on Free is unchanged.
PlumiBot could translate into 126 languages but could only talk in seven. A Spanish group got its help screens, error messages and setup questions in English anyway. Now every language it can translate into is one it can speak to you in.
!setlang takes a code exactly as written — zh-cn, pt-br and mni-mtei no longer bounce.The guard that watches for people trying to hijack the translator matched the word “DAN” whatever its case — and dan is simply “and” in Indonesian and Malay. Indonesian chats were having nearly every message refused. A suspicious signal now hardens the instructions we send the model instead of dropping your message.
Every automatic email still wore the old template, and receipts were quoting prices from two pricing models ago. All eleven have been redrawn in PlumiBot's own colours, and their plan names and amounts now read from the same source this website does — so they can't drift apart again.
Pay-as-you-go credit came in three fixed sizes. Now there are six one-tap amounts up to NT$3,000, and a field for typing your own — so a top-up can match what you actually expect to use instead of the nearest button.
We benchmarked our models against each other on real chat. The cheaper one translated just as well and answered several times quicker — so every plan now translates chat on it, Free included. Paying more buys you more translation, not a better sentence.
Translation now runs through a provider gateway instead of a single vendor, so one outage can no longer take the bot down, and the Free tier is now honest about what it covers.
The language list grew from a shortlist to 126 — and every menu button in LINE now goes where its label says.
Signing in and everything behind it — usage, billing, top-ups, settings — now reads in the same 14 languages as the rest of the site.
PlumiBot gets the retro-computing wardrobe it always deserved — a whole new site, rebuilt page by page.
Every plan's monthly quota grew by a large multiple, and pay-as-you-go moved to one flat rate per message. Nothing costs more than it did.
Usage, billing and group settings in one place — sign in with !login and PlumiBot sends you a link.
A security and performance pass across the whole web layer, plus faster first loads.
