200 million users message businesses on LINE every day
LINE is the primary messaging platform across Japan, Thailand, Taiwan, and Indonesia. If your customers are in these markets, your support needs to be on LINE — and it needs to be instant.
LINE is the dominant messaging app in key Asian markets
If your customers are in Japan, Thailand, Taiwan, or Indonesia, LINE is likely their primary messaging app — not WhatsApp, not Messenger. To serve them where they are, you need to be on LINE.
Your support team can't respond to every LINE message manually
As your LINE follower count grows, inbound messages scale with it. Frequently asked questions arrive repeatedly. An AI chatbot trained on your knowledge base handles the volume without adding headcount.
Customers expect instant replies — even on messaging apps
When someone messages your LINE Official Account, they expect a response faster than an email. A VocUI LINE chatbot answers immediately from your documentation, around the clock.
Connect your knowledge base to LINE in three steps
Train on your business docs
Upload your FAQs, product guides, service policies, and any content your LINE followers commonly ask about. VocUI indexes everything and makes it queryable in natural language.
Connect your LINE Official Account
Link your LINE Official Account via the Messaging API. VocUI configures the webhook so every inbound message is automatically answered by your trained AI.
Answer followers instantly
Followers message your account naturally. VocUI finds the relevant content from your knowledge base and sends back an accurate reply — for free, in any language your docs cover.
Everything your LINE Official Account bot needs
Not just auto-replies. VocUI answers from your documentation and tells users exactly where the answer came from — in the conversation they already trust.
Free reply messages
LINE reply messages — sent in response to an inbound message — are free on all plans. VocUI's chatbot only ever sends replies, so there is no per-message cost for automated responses.
1:1 chats and group chats
VocUI works in direct 1:1 conversations with followers and in group chats when @mentioned. One deployment covers both interaction types.
Trained on your content
Upload PDFs, URLs, product docs, and policies. Your LINE bot answers from your actual documentation — not generic AI guesses or hallucinations.
Always up to date
When your docs change, update your knowledge sources in VocUI. Your LINE bot answers from the latest version immediately — no redeployment needed.
Multi-channel from one knowledge base
The same knowledge base powers your LINE Official Account bot and your website chat widget. One source of truth across every channel.
Usage analytics
See which questions get asked most and which go unanswered. Use the data to improve your knowledge base and identify gaps in your content.
What businesses use VocUI LINE chatbot for
From customer support to sales qualification — if your audience is on LINE, your knowledge base should be there too.
