Built on LINE, for service businesses
Your AI operations assistant — customer service, booking, CRM and marketing in one place
Jiuwei helps service-business owners answer customers, take bookings, manage their customer base and win repeat business — with AI doing the busywork and LINE at the core.
Everything a service business needs, in one system
Instead of stitching together separate tools, Jiuwei keeps enquiry → booking → visit history → re-engagement in a single flow.
AI customer service
Automatically answers LINE enquiries around the clock. Every message is PII-masked and screened for crisis signals before it reaches the AI; sensitive conversations are handed to a human.
Online booking
Customers pick a time and service themselves through LINE (LIFF). The engine prevents double-booking and respects each staff member’s availability.
Customer CRM
Visit history, tags, packages and staff commission — all kept with snapshots so your records never drift.
Re-engagement marketing
Automatic reminders and win-back messages based on each customer’s visit history, so quiet customers come back.
Payments
Collect deposits and online payments through LINE Pay, ECPay and Stripe.
Social & calendar
Native Instagram customer service (comment-to-DM and story replies), a Threads inbox, and one-way Google Calendar busy-time sync so customers never book over your existing plans.
Where AI helps — and where it stops
Jiuwei’s AI is a booking and customer-service assistant. Every message is PII-masked and screened for crisis signals before the AI sees it, and sensitive or high-risk conversations are routed to a real person rather than answered automatically. Your data is used only to run your own store’s service — it is never sold or used for advertising.
