1Common Challenges
The same questions all day
Prices, location, opening hours, how to book. Your admins type the same answers again and again instead of helping customers who are ready to buy.
AI picks, never writesBuilt for LINE OA
LINE AI Chatbot That Answers Customers 24/7
List the questions customers ask most, add keywords and pick a Rich Message card as each answer. The bot replies in 1:1 chats day and night. When a message misses your keywords, AI picks the best of your approved answers. It never writes its own, so no invented prices or promises reach your customers.

Common Challenges
Why LINE chats pile up
If these sound familiar, a chatbot helps. Further down, we also say plainly what it can't do.
2Common Challenges
Messages arrive after closing time
Late-night and holiday messages wait until morning, and some customers ask another shop in the meantime.
3Common Challenges
Customers rarely type your exact keyword
One writes “price”, another “how much”, a third misspells it or mixes Thai and English. A fixed keyword list misses them.
4Common Challenges
Generic AI bots can make things up
Bots that let AI write the answer can quote a price, discount or policy you never offered, and your team has to clean up afterwards.
5Common Challenges
Asking for a person gets another bot reply
When a customer types “I want to talk to someone” and still receives automatic messages, frustration grows fast.
6Common Challenges
Plain text has no next step
A text answer can't show a photo or a Book now button, so customers have to ask again where to go next.
How It Works
Set up your LINE chatbot in 5 steps
No code, all in the browser. The longest part is writing down what customers ask you.
1
Create your reply cards
Tell the AI what each answer should say, such as a price list, this month's offer or how to book, and get a Rich Message card with an image, headline, text and button. 8 credits per card, paid once, reusable without limit.
2
Connect your LINE OA
Enable the Messaging API for your account in LINE OA Manager, then paste the Channel ID, channel secret and channel access token from the LINE Developers console into LineBot.pro.
3
Add intents and keywords
Up to 8 intents per LINE account, each with up to 15 keywords in any language. Choose the card each intent replies with.
4
Test for free in the simulator
Type a sentence the way a customer would. The simulator shows the intent it matches, a handoff request or no match. No credits used, nothing sent.
5
Paste the webhook and switch it on
Copy the webhook URL into LINE Developers, turn on Use webhook and press Verify. When you activate the bot, every reply card is checked by LINE first.
Key Features
What the LINE chatbot does today
Everything below is live in the app. Nothing here is “coming soon”.
Keywords found anywhere in a sentence
Set “price” and a customer who writes “what's the price for two?” still gets the answer. English keywords match whole words, so “hi” never fires on “shipping”.
Answers as Rich Message cards
Each answer is a card with a 1200×675 image, a headline, short text and a button such as Book now or See menu, plus an optional Call us button.
AI routing for everything else
Optional. When no keyword matches, AI (Gemini Flash) picks the closest intent and replies only when it is at least 85% confident. 1 credit per message the AI reads.
No made-up answers
The AI chooses, it never writes. Customers only receive cards you created and approved, so prices, offers and policies stay exactly as you set them.
A handoff that really stops the bot
Phrases like “human”, “แอดมิน”, “担当者” and “真人客服” come preset and editable. When one appears, the bot goes quiet for that customer until you switch it back on.
A daily cap on AI credits
Set the maximum AI credits per day (default 20, up to 200). Once it is reached, AI routing waits for the next day while keyword replies keep working.
Free simulator
Try any customer sentence before going live and see which intent its keywords match. Simulations cost nothing and send nothing; AI routing only runs on real messages once the bot is active.
Daily counters
See today's replies sent, failed attempts and AI credits used (UTC day), and pause the whole bot in one click.
One bot, four languages
Mix Thai, English, Japanese and Chinese keywords in the same intent. Reply cards can be generated in Thai, English, Japanese or Traditional Chinese.
How it decides
What the bot does with every message
Four rules, checked in this order. No black box.
- Bot paused
The message asks for a person
The bot stops replying to that customer. Your team answers in LINE OA Manager chat and switches the bot back on afterwards.
- 0 credits
Keywords of exactly one intent are found
That intent's reply card is sent.
- 1 credit
No keyword matches, or keywords of several intents match
If AI routing is on, the AI picks one of your intents, but only at 85% confidence or more and within your daily cap.
- No reply
The AI isn't sure, is off, or the cap is reached
Nothing is sent. The message waits for your team in LINE OA Manager chat, as it does today. The bot never guesses.
The bot answers text messages in 1:1 chats. Group chats, stickers and images are left to your team.
Honest comparison
LINE's built-in auto-reply or a chatbot?
LINE OA Manager already includes free auto-reply messages, and for many shops they are enough. Here is a straight way to choose.
Stay with LINE's auto-reply if…
- You have a few questions and customers ask them in the same words
- A short text answer is enough
- You'd rather not set up the Messaging API and a webhook
- You want everything to stay free
Use the LineBot.pro chatbot if…
- You want answers as cards with an image and a button
- Customers phrase things many ways, mix languages or make typos, and AI routing should catch them
- The bot must go quiet as soon as someone asks for a person
- You want to test before going live and check daily numbers
Running both? Turn off LINE's auto-reply for the questions the bot covers, or customers may get two answers.

Contact UsFrequently Asked Questions
LINE chatbot FAQ
What is a LINE chatbot, and how is this one different from LINE's built-in auto-reply?
A LINE chatbot answers the messages customers send to your LINE Official Account automatically. LINE OA Manager already includes free auto-reply messages, and for a handful of simple questions they are enough. LineBot.pro adds reply cards with an image and a button, keywords that are found anywhere in a sentence, optional AI routing for messages your keywords miss, and handoff phrases that stop the bot for a customer who asks for a person.
How much does a LINE chatbot cost?
There is no monthly fee. Keyword replies cost 0 credits. AI routing costs 1 credit per message the AI reads, with a daily cap you set. Each reply card costs 8 credits once, when you create it, and can be sent any number of times. New accounts get 50 free credits without a card, enough for 6 reply cards. After that, credits come in one-time packs that don't expire.
Can the AI make up prices or promises?
No. The AI never writes text. It only chooses one of the reply cards you created and approved, and only when it is at least 85% confident. Otherwise the bot sends nothing and the message waits for your team in LINE OA Manager chat.
What happens when a customer asks for a real person?
If a message contains a handoff phrase, the bot stops replying to that customer. Defaults include “human”, “real person”, “live agent”, “แอดมิน”, “担当者” and “真人客服”, and you can edit the list. Your team answers in LINE OA Manager chat, then switches the bot back on for that customer from the automation page. There is no separate inbox or notification, so keep checking your LINE chats as usual.
Do bot replies use my LINE message quota?
No. The bot answers through LINE's Reply API, and reply messages are not counted in your monthly message quota (LINE Developers documentation, October 2026). Messages your account initiates, such as broadcasts, are counted.
Do I need to code to set it up?
No. You create reply cards, connect your LINE OA with its Channel ID, channel secret and channel access token, add intents and keywords, test them in the free simulator, then paste the webhook URL into the LINE Developers console. Before the bot goes live, every reply card is checked by LINE's validation endpoint.
Does it work with Thai, Japanese and Chinese messages?
Yes. Keywords can be written in any language and are found inside a sentence, which matters for Thai, Japanese and Chinese because they don't put spaces between words. AI routing reads all four languages, and reply cards can be generated in Thai, English, Japanese or Traditional Chinese.
Can you build a custom LINE chatbot connected to our booking system or CRM?
The chatbot in the app answers with approved cards; it does not read booking, stock or CRM data. If you need that, we take on custom LINE development on request. Describe the project in the contact form and we will reply with a scope and a quote.
