1Common Challenges
The same five questions, all day
Price, opening hours, location, delivery, how to order. Every answer is typed by hand — and customers wait whenever the admin is off.

Common Challenges
Why LINE OA admins burn out
Most LINE Official Accounts are run by one or two people who answer the same questions, design every promotion and have to remember to press send.
2Common Challenges
Plain-text replies that don't sell
Built-in keyword replies are usually plain text. A card with a picture, a short pitch and a button to the right page turns a question into the next step.
3Common Challenges
Promotions that depend on memory
Campaign visuals get made at the last minute, and the broadcast goes out late — or not at all.
4Common Challenges
Bots that make things up
Generative chatbots can answer with prices or promises you never made. On a business account, one wrong answer costs more than the time it saved.
5Common Challenges
No clean way back to a person
When a customer asks for a human, a bot that keeps replying is worse than no bot at all.
6Common Challenges
Monthly fees before you know it works
LineBot.pro is pay-as-you-go: keyword replies are free, credits come in one-time packs with no subscription, and they don't expire.
How It Works
From sign-up to your first automated reply
Everything is self-serve. Most of the time goes into choosing which questions deserve an automated answer.
1
Sign up free
Sign in with LINE or an email link and get 50 free credits. No card, no subscription.
2
Connect your LINE OA
Paste your Messaging API Channel ID, Channel secret and access token, then add the webhook URL we show you in LINE Developers and turn on Use webhook.
3
Set intents, schedule campaigns
Create the reply messages with AI, add 1–8 intents with up to 15 keywords each, and schedule the campaigns you have planned.
4
Test, activate, watch the counters
Try customer phrases in the free simulator, activate, then follow the daily counters: replies sent, failed attempts and AI credits used.
Key Features
What the LINE OA automation tool does
Three jobs — answering, sending and creating — in one place, with the limits stated up front.
Keyword routing to approved replies
Group questions into 1–8 intents per LINE account, each with up to 15 keywords. Matching ignores case and full-width/half-width differences, and English keywords match whole words only — “hi” won't fire on “shipping”.
Rich message replies, not plain text
Each intent answers with a rich message you generated and approved: picture, headline, short text and a button. Creating one costs 8 credits; sending it as a reply costs nothing.
Optional AI routing, no invented answers
When no keyword matches, the AI may pick the closest intent — only if it is at least 85% confident, and only ever one of your approved replies. 1 credit per message the AI checks, with a daily cap you set.
Human handoff keywords
Words like “human”, “แอดมิน”, “担当者” or “真人客服” pause automation for that customer only, so your team takes over in LINE's own chat. Resume them from the automation page.
Scheduled campaigns
Send to all friends or to a list of LINE user IDs, now or at the date and time you pick. Sending costs 0 credits; your LINE plan's monthly message quota applies.
AI Studio content kit
One brief creates a wide banner, a rich message and a 3-button compact rich menu together (26 credits for the full kit). Your brand profile — colour, tone and rules — is applied to every image.
Thai, Japanese, Chinese and English
Create content in Thai, Japanese, Traditional Chinese or English; the language of your prompt is detected. Keywords and handoff phrases work in any language you type.
Free simulator and daily counters
Test what a customer might type before going live — the simulator is free and sends nothing. Once active, daily counters show replies sent, failures and AI credits spent.
Safe activation
Automation starts switched off. Before you activate it, LINE validates every reply message, so a broken message never reaches a customer.
Workflow
How the three parts fit together
Create a message once, then use it to answer questions and to run campaigns. Each step links to the tool, and to a guide if you want the background.
1 · Create
Make the messages once
Generate the rich messages your replies and campaigns will use — or a full kit (banner, rich message, rich menu) from one brief in AI Studio.
2 · Answer
Route questions to them
Map each common question to one of those messages, test it in the simulator, then activate. Short of wording ideas? Start from these LINE auto-reply message examples.
3 · Send
Schedule the campaigns
Pick an approved message, choose all friends or a list of user IDs, and schedule it. Before a big send, read how LINE counts broadcast messages.
Good to know before you start
- Works on 1:1 text chats. Group chats, stickers and photos are skipped.
- No greeting message on follow — keep using LINE's own greeting message.
- No conversation trees, drag-and-drop builder or AI-written answers.
- No inbox or live chat: your team answers in the LINE Official Account chat.
- No open or click analytics, tags or step sequences.
- If LINE's own auto-responses stay on for the same keywords, customers get two replies — switch off the overlap.

Contact UsFrequently Asked Questions
Frequently Asked Questions
What can the LINE OA automation tool automate?
Three jobs. It replies to common questions in 1:1 chats (keywords → a rich message you approved, with optional AI routing), sends scheduled campaigns to all friends or to a list of user IDs, and creates the visuals for those messages with AI. It does not run conversation trees, AI-written answers or step sequences.
Does the AI write its own answers to customers?
No. The AI only decides which of your approved replies fits a message that matched no keyword, and only when it is at least 85% confident. Otherwise it stays silent and your team answers. It never invents prices, promises or links.
How much does it cost?
Keyword replies cost 0 credits. AI routing costs 1 credit per message it classifies, capped by a daily limit you choose (20 by default, up to 200). Creating a rich message with AI costs 8 credits and sending a campaign costs 0 credits. You start with 50 free credits, then buy one-time credit packs — no subscription, and credits don't expire.
Do automated replies use my LINE message quota?
No. Replies to a customer's message go out through LINE's reply API, which is not counted in your LINE Official Account's monthly message quota. Campaign sends — to all friends or to a list of user IDs — are counted per recipient.
What happens when a customer asks for a person?
Handoff keywords such as “human”, “แอดมิน”, “担当者” or “真人客服” — plus any you add — pause automation for that customer only. Your team replies in the LINE Official Account chat as usual, and you resume automation for that customer from the automation page. LineBot.pro has no inbox of its own.
Do I need a developer to connect my LINE Official Account?
No coding is needed, but you need access to LINE Developers. Enable the Messaging API for your account in LINE Official Account Manager, copy the Channel ID, Channel secret and access token into LineBot.pro, then paste our webhook URL in the LINE Developers Console and turn on Use webhook.
Will it clash with the auto-replies I set in LINE Official Account Manager?
It can. If LINE's own auto-response messages stay on for the same keywords, a customer may get two replies. Keep LINE's greeting message, and switch off overlapping auto-responses once your LineBot.pro intents are active.
Does it work in group chats, or with photos and stickers?
No. Automation answers text messages in 1:1 chats with your LINE Official Account. Stickers, photos and group conversations are skipped, so your team handles them in the chat.
