How it works
Watch OneChat answer, right inside LINE
No new app for your customers, no dashboard for them to find. The whole conversation happens on the LINE screen they already use.
A customer messages you on LINE
A customer messages your LINE Official Account about their order — in Japanese, at lunchtime, while your team is slammed.
OneChat starts typing the moment the message lands.
OneChat answers in seconds — with a real answer
OneChat looks up the order status in your knowledge, answers in natural Japanese inside LINE — 既読 in seconds — and switches language automatically if the next customer writes in English or Thai.
Not a canned away-message: it reads the question and answers it from your business knowledge.
When it needs a human, your team gets pinged in Slack
Refunds, edge cases, angry customers — OneChat knows when to stop and escalates to your Slack with the full LINE conversation attached. Your teammate takes over mid-chat; the customer never repeats themselves.
🔔 Handoff requested — Maria on LINE wants to change the shipping address on a paid order.

FAQ
LINE auto-reply, answered
Does OneChat work with LINE Official Accounts?
Yes. OneChat connects to your LINE Official Account through the official Messaging API. Your rich menus, coupons and broadcasts keep working — OneChat handles the replies.
Can OneChat answer LINE voice messages?
Yes. OneChat transcribes LINE voice messages automatically and answers them like any other chat, in the language the customer used.
How is this different from LINE’s built-in auto-reply?
Built-in auto-replies send the same canned message to everyone. OneChat reads each question and answers it from your actual business knowledge — order status, sizing, shipping, returns — like a trained teammate would.

About 15 minutes. Paste your website URL, connect LINE, review a few test answers, and you’re live — today.
