SATSUMA CREATIVE / TAIPEI — LINE BOT & AI ★ OPEN FOR PROJECTS

The "auto-reply" in your LINE Official Account is not AI customer support.The difference is whether your data actually goes in.

Auto-reply is akeyword lookup table— one character off and it stays silent. AI support has to understand "can I return the thing I bought last week" — which means knowing what you sell and what your rules are. If it can't find the answer, it says so and hands off to a humaninstead of guessing something that merely sounds right.

From NT$50,000 · Live in 3–5 weeks · Three production cases, every URL clickable and verifiable

Situation 1

Dozens of keywords configured, and customers still ask in words you never set up — so everything falls back to a human anyway.

Situation 2

You subscribed to an AI support SaaS, and six months later nobody opens the dashboard — because it never really understood your products.

Situation 3

You answer the same question twenty times a day, while the customers who actually need your time wait in line.

01 / The difference

Three different things are all called a "LINE bot,"and prices differ tenfold

Work out which one you need first, then talk pricing. Most people assume they need the third; the second is usually enough.

i.

Keyword auto-reply

Built into LINE Official Account — no development needed
  • You set "opening hours," and the customer has to type "opening hours"
  • One character off and it stays silent
  • More questions means keyword management hell
  • Best for: small shops with fewer than 10 types of questions
Free / set it up yourself
Honestly you don't need us for this
ii.

AI customer support (knowledge-base type)

Understands natural language, answers only from your data
  • Understands customers however they phrase it
  • Answers sourced strictly from your knowledge base (RAG)
  • Can't find it → says so → hands off to a human
  • Prices, stock and other live figures pulled by code in real time
  • Best for: most businesses with fixed products and rules
From NT$50,000 / from $1,800
Timeline 3–5 weeks, including website integration
iii.

A bot that gets things done

Not just answers — it takes orders, dispatches jobs, collects payment
  • Everything above, plus:
  • Bookings / orders / dispatch written to a database
  • Subscription payments (ECPay / MyCard)
  • Integration with existing CRM, POS, membership systems
  • Best for: high support volume or workflows that need automating
Quoted by scope / reviewed before quoting
Timeline Depends on the systems being integrated
Not sure which one you need?Throw your support questions at Xiao-Ai— it's exactly the second type described on this page, so you can test how well it answers for yourself.
02 / What you get

What we buildactually looks like this

01

Knowledge base setup

The most important step in the whole project

Send us your existing product descriptions, price lists, FAQs, return policies, old support conversations — any format. We turn them into a knowledge base the AI can actually read. Get this wrong and no model will save you.

02

Answers only from your data

RAG — no improvising

We retrieve from your knowledge base first, then let the AI answer based on the retrieved passages. If it can't find the answer, it says so instead of guessing something that merely sounds right.

03

Figures that change aren't left to the AI

Prices, stock, time slots

Data like this is always pulled from live sources by code and handed to the AI, which only has to phrase it in plain language. AI-generated numbers are where complaints come from.

04

Rich Menu and guided flows

Not every customer wants to type

Bottom rich menus, quick reply buttons, multi-step flows — if it can be tapped, don't make customers type it.

05

Human handoff in one line

The bot knows when to stay quiet

When a customer asks for a human, or the AI can't answer, the bot locks itself out and the conversation goes straight to your Telegram, where you reply to the customer directly.

06

Hard usage caps

No runaway bills

Daily and per-user AI call limits, with automatic handoff to a human beyond them. Model costs run on your own API account — we take no cut.

03 / Pricing

From NT$50,000 —the quote is the total

Quoted based on knowledge base size, whether existing systems need integrating, and whether you need multiple platforms. No extra hours added after it's confirmed.

i.

AI bot for LINE / messaging platforms

Includes website integration. Telegram and WhatsApp run on the same backend
  • LINE Official Account setup and Rich Menu
  • Knowledge base setup and RAG responses
  • Human handoff (two-way via Telegram)
  • Website integration (one knowledge base shared across both)
  • Usage caps and cost guardrails
  • 30 days of free tuning after launch
From NT$50,000 / from $1,800
Timeline 3–5 weeks, including deployment
ADD-ONS

Subscription payments

ECPay or MyCard subscription integration, turning the bot itself into a product that collects payment. That's exactly how our own tarot subscription runs.

Booking flows

Booking built into the same bot: only available slots shown, atomic slot locking, two-stage reminders. See LINE booking system, from NT$45,000.

Integration with existing systems

CRM, POS, ERP, membership databases. Priced separately depending on whether the other system has an API — this one we review before quoting.

The above arestarting prices; actual quotes depend on scope. Once a quote is confirmed it's the total —no added hours, no hidden fees
Your LINE Official Account monthly fee and AI model usage are paid directly to the providers.The account is registered in your name; we neither collect on your behalf nor take a cut

Launch-period support — 120 tickets a week

Support volume spiked at game launch, repeat questions ate most of the manpower, and the real problems got pushed to the back of the queue.

Result Of these,60% resolved by AI directly; the rest handed to humans with the prior conversation attached, so agents never had to ask twice.

05 / Process

Four steps,progress you can see

01

Discovery

30 minutes · quote same day

We look at what your support messages actually look like and which questions repeat most. This step decides whether you need AI at all — if keyword replies are enough, we'll say so.

02

Knowledge base preparation

1–2 weeks

You send existing material; we turn it into a knowledge base and run offline tests first — asking it your real past questions and measuring how many it gets right. That score decides whether we continue.

03

Development and trial run

3–5 weeks

You get a test account first and play customer for a few days. Wrong answers are fixed in the knowledge base on the spot, not in the model.

04

Handover

30 days of tuning after launch

The Official Account, knowledge base, source code and dashboard all go to you, with documentation. After that you maintain the knowledge base yourself — no need to come back to us.

06 / FAQ

Common questions,answered directly

How much does LINE bot development cost?

From NT$50,000, live in 3–5 weeks, including LINE Official Account setup, Rich Menu, AI responses and knowledge base setup, human handoff and website integration. Subscription payment integration is optional.

Actual quotes depend on knowledge base size, whether existing systems need integrating, and whether you need multiple platforms. Once confirmed, the quote is the total.

What's the difference between the built-in LINE Official Account "auto-reply" and AI customer support?

Auto-reply isa keyword lookup table: the customer's wording has to match yours exactly, and one character off means silence.

AI support understands things like "can I return the thing I bought last week" — which means knowing what you sell and what your rules are.The difference isn't how smart the model is; it's whether your knowledge base actually goes in.Skip that step and every AI performs the same.

What material do I need to prepare?

Whatever you already have: product or service descriptions, price lists, FAQs, return and booking policies, past support conversation logs.

Any format — Word, Excel, web pages, even LINE chat screenshots. We handle the organising.Knowledge base quality determines answer quality— it's the most important step in the whole project.

Will the AI make things up and offer plans we don't have?

It will, if nothing is done about it. We use RAG: relevant passages are retrieved from your knowledge base first, then the AI answers based only on those passages; if nothing is found it admits it and hands off to a human.

Figures that change — prices, stock, booking slots — are always pulled from live sources by code,never generated by the AI

Can it run on Telegram or WhatsApp at the same time?

Yes. The same backend serves different platforms; the main differences are message formats and account application processes.

Taiwanese customers are mostly on LINE, but if you have overseas customers, Telegram and WhatsApp are worth doing alongside it. Pricing depends on the number of platforms.

Roughly how much does the AI cost per month?

It depends on message volume, not a fixed monthly fee. In the proposal we'll estimate a range based onyour actual support message volume.

The system hard-codes usage caps (automatic human handoff beyond them) to avoid runaway bills. Model costs run on your own API account —我們不從中抽成

Can a customer be handed to a human mid-conversation?

Yes, and it's essential. When a customer asks for a human, or the AI determines it can't answer, the bot locks itself out and the conversation goes straight to your Telegram, where you reply to the customer directly and hand it back when you're done.

Who holds the LINE Official Account and the data?

You do. The Official Account is registered in your name, and the knowledge base, conversation logs and source code are handed over to you — export or switch maintainers anytime.
