Option 1: LINE OA’s built-in AI Chatbot
LINE Official Account offers an AI Chatbot as part of the OA Chat Package at THB 555 per month plus 7% VAT. It picks the most suitable answer from a Q&A set the business creates, and can generate that set from PDF or image files (JPEG, PNG). The same package extends chat history to 5 years and adds chat tags and notes.
Good for repetitive questions with stable answers. The limit is that answers come from a prepared Q&A set. If they depend on data that changes daily, like stock or free slots, someone has to keep editing it.
Option 2: an off-the-shelf chatbot platform
Several providers combine LINE, Facebook and other channels, with bot builders and a shared inbox for admins, on monthly plans. They’re fast to start. What to check: how well they connect to data in your own systems, and who holds your customer data.
Option 3: a system connected to your data
A system receives LINE messages through the Messaging API (and Facebook if needed), has a language model answer using live data such as stock, free slots and order status from your systems or the Google Sheets you already use, and hands over to an admin when a question is out of scope. Costs come in three parts:
- A one-off build, depending on the channels and systems it connects to.
- AI usage at cost, usually a fraction of a baht to a few baht per conversation, depending on length and model.
- LINE messaging: replies to customer messages don’t count toward your monthly quota. Messages you send out yourself, such as reminders or promotions (push, broadcast), do.
Which one fits
| Your situation | Start with |
|---|---|
| Customers ask the same things: hours, location, basic prices | LINE OA AI Chatbot |
| Several channels, and admins want one inbox | An off-the-shelf platform |
| Answers need stock, bookings or order status that change daily | A system connected to your data |
| Your own process, such as deposits or membership checks | A system connected to your data |
What to watch, whichever you choose
- AI can be wrong. Restrict it to your data and have it hand over when unsure. Never let it guess prices or terms that aren’t in your data.
- Tell customers they’re talking to an AI, and always offer a way to reach a person.
- Customer data falls under Thailand’s PDPA. Keep only what you need, set retention, and know where each provider stores data.
- Test with your real chats before launch. Every business has its own product names and the way its customers type.

Questions people ask
Is the LINE OA AI Chatbot free?
No. It requires the OA Chat Package at THB 555 per month plus 7% VAT, per LINE for Business as of September 2026.
Does a bot replying on LINE cost message quota?
Replies to customer messages don’t count toward a LINE OA’s monthly message quota. Messages the business sends out itself (push, broadcast) do.
What if a customer wants a real person?
A good system always has a way out, such as a button or command that hands the chat to an admin with a summary, so the admin doesn’t have to ask again.
