How it works

  1. Add KrubKa

    Add @858tccji as a friend on LINE, or invite it into any group chat.

  2. Chat normally

    Everyone writes in their own language. KrubKa translates every message both ways, right in the chat.

  3. Go further with the app

    The KrubKa app connects your LINE account, shows your usage and groups, sets how your Thai sounds, and unlocks Unlimited.

Works in LINE

Everyone keeps chatting normally

Invite KrubKa into a group — with your landlord, your partner, your partner's family. It translates each message in place, so both sides read and reply in the language they think in.

Photo translation

Send a photo. Understand what matters.

Electricity bill, condo notice, government letter — snap a photo in your 1:1 chat with KrubKa and it tells you what it is, how much, and when it's due.

Managed in the app

Polite Thai that sounds like you

Thai politeness is built in. Pick ครับ (krub) or ค่ะ (ka) in the app and KrubKa ends your translated sentences the way you would say them.

Conversations shown are illustrative test chats.

Made for the everyday stuff

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 else, no copy-pasting into a translator.

Frequently asked questions

What is KrubKa?

An AI English ↔ Thai translator that lives inside LINE. Chat 1:1 with the KrubKa official account (@858tccji), or invite it into a group — it translates every message in both directions, in polite, natural Thai.

Do my Thai contacts need to install anything?

No. Nobody else in the chat needs the app or an account. They just keep using LINE as they always have.

How much is free?

You get 50 free translations each month, shared between your 1:1 chat and the groups you're connected to. A group where nobody has connected KrubKa yet gets a one-time trial of 10 translations.

What does Unlimited cost, and what do I get?

$4.99 per month or $39.99 per year. Your 1:1 translation becomes unlimited, and the groups you're in are covered for everyone under a generous fair-use ceiling.

Can it translate photos?

Yes, in your 1:1 chat: 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 group chats are not translated.

What about voice messages?

Not yet. KrubKa replies that voice isn't supported, and it doesn't use up any of your translations.

What is the KrubKa app for?

The bot works without it. The app adds sign-in, connecting your LINE account, seeing your usage and groups, choosing how your Thai sounds (ครับ or ค่ะ), and subscribing to Unlimited.

Can I pause it in a group?

Yes — type /pause in the chat to stop translating and /resume to start again. /krub and /ka switch your polite particle.

What happens to my photos and messages?

Photo and media bytes are processed in memory and discarded — never stored. Message text is processed to produce the translation. The privacy policy linked below has the details.

Does it translate other languages?

No — KrubKa does English ↔ Thai only, by design. Doing one language pair well is the whole point.
