On a computer? Scan with the LINE app.
Add @858tccji as a friend on LINE, then invite it into any chat you already have — with one person or a whole group.
Everyone types or sends voice messages in their own language. KrubKa translates every message both ways, right in the chat.
Free covers 50 translations a month. Need more? Send /upgrade and pay on a checkout page that opens right in LINE. No app to install.
Works in LINE
Invite KrubKa into the chat you already have — with your landlord, your partner, your partner's family. No need to make a group first. It translates each message in place, so both sides read and reply in the language they think in. Voice messages are translated too, in beta.
Photo translation
Electricity bill, condo notice, government letter — snap a photo in your private chat with KrubKa and it tells you what it is, how much, and when it's due.
Polite by default
Thai politeness is built in. Type /krub (ครับ) or /ka (ค่ะ) in the chat, or flip the toggle in the optional app, and KrubKa ends your translated sentences the way you would say them.
Conversations shown are illustrative test chats.
A leaky air conditioner, a package at the gate, dinner plans with your partner's family. KrubKa keeps those conversations moving in the LINE chats you already have — no new app for anyone, no copy-pasting into a translator.

An AI English ↔ Thai translator that lives inside LINE. Message KrubKa privately (@858tccji), or invite it into any chat you already have — with one person or a group — and it translates every message — typed or voice — in both directions, in polite, natural Thai.
No. Everything happens in LINE: add @858tccji, invite KrubKa into your chats, connect a shared chat with /connect, set ครับ or ค่ะ with /krub or /ka, and go Unlimited by sending /upgrade — a secure checkout opens right inside LINE. The KrubKa app is optional.
No. Nobody else in the chat needs the app or an account. They just keep using LINE as they always have.
You get 50 free translations each month, shared between your private chat with KrubKa and the chats you've connected. A chat where nobody has connected KrubKa yet gets a one-time trial of 10 translations.
$4.99 per month or $39.99 per year. Your private translation becomes unlimited, and every chat you've added KrubKa to is covered for everyone under a generous fair-use ceiling. Subscribe right in LINE by sending /upgrade to KrubKa, or in the app.
If you subscribed in LINE, use the link in your purchase confirmation email. If you subscribed in the app, cancel in your App Store or Google Play subscriptions. Either way, Unlimited stays on until the end of the period you paid for.
Yes, in your private chat with KrubKa: send a photo of a bill, letter, or sign and KrubKa explains what matters — the amount, the due date, what to do. Photos sent in shared chats are not translated.
Yes, in beta, both ways: a Thai voice message comes back in English, an English one in Thai. Send a voice message of up to 5 minutes, in your private chat with KrubKa or in a shared chat, and KrubKa replies with what it heard and the translation. Each voice message counts as one translation.
It's optional: the bot works fully without it. The app shows your usage and your chats and has a ครับ/ค่ะ toggle. You can subscribe there too.
Yes — type /pause in the chat to stop translating and /resume to start again. /krub and /ka switch your polite particle.
Photos and voice-message audio are processed in memory and discarded — never stored. Message text, including what KrubKa heard in a voice message, is processed to produce the translation. The privacy policy linked below has the details.
No — KrubKa does English ↔ Thai only, by design. Doing one language pair well is the whole point.
