Bookings and questions, answered on LINE automatically.
I'm Rio Shintani. I build bots (programs that reply automatically) for your shop's or company's LINE Official Account, shaped around how your business already works.
Sample: a demo for a fictional hair salon, "Salon Sakura". When a customer messages on LINE, the bot checks open times, takes the booking and tells the staff.
What is a LINE bot?
A LINE bot is a program that replies to your customers' LINE messages automatically, 24 hours a day.
Many shops and companies already talk with customers through a LINE Official Account. Connecting a bot lets it take bookings and answer common questions in place of your staff. People step in only when they're really needed.
- A customer messages on LINE "Can I book for tomorrow?"
- The bot looks it up Checks your booking sheet and shop info
- It replies right away Confirms the booking and notifies staff
- LINE Official Account
- A business account that lets shops and companies connect with customers on LINE. You can start for free.
- Bot
- A program that replies to messages automatically, using set rules or AI (artificial intelligence).
- Integration
- Connecting the bot to your booking sheet or customer list (for example, a Google Sheet).
What it does
Taking bookings and sending reminders
The bot takes over checking availability and replying to each phone call or LINE message one by one. It also sends the day-before reminder automatically.
-
Before
Checking the booking sheet and replying with open times by hand, then calling the day before to confirm
-
With a bot
Customers pick a time on LINE and the booking is done. Reminders go out automatically
-
Automatic answers to common questions
AI answers questions about hours, prices, parking and more, using your shop's own information. Anything it can't answer goes to your staff.
-
Booking sheet and customer list integration
Bookings and inquiries that come in on LINE are written automatically into the sheet you already use, such as a Google Sheet.
-
Staff notifications
New bookings and inquiries are sent straight to your staff, for example in a staff LINE group.
-
Pages that open inside LINE
Membership cards, point cards and order forms that customers use inside LINE without installing an app (LIFF).
Work
I build chat bots and work automation, and they run every day.
A LINE bot works by receiving a message, looking things up and replying. I've designed, built and run bots and automation tools that work the same way.
-
A relay server for chat bots
For a bot on the chat app Telegram, I built from scratch a system that sorts incoming messages so several programs can share one bot at the same time. It runs nonstop on my own server.
-
Automation you control from chat
I built a setup where sending a command from a phone chat pauses an automation tool on a computer or reports its status.
-
A work tool for a large manufacturer
I built it on my own. It saves 3+ hours per document, and 200+ people use it every day.
-
A LINE booking bot demo
Like the sample at the top of this page, I have a booking, reminder and Q&A bot built around a hair salon, so you can see how it works.
