Customer chat software in Thailand: 3 types compared
Keyword auto-replies, rule-based chatbots and AI agents: what each one really handles, what it costs per month, and how to pick one without overbuying.
LINE & Chat · 8 min read
Short answer: customer chat software in Thailand comes in three families, and the right one depends on how many of your questions are repeats. Keyword auto-replies only echo what you configured. Rule-based chatbots follow flows you script in advance. AI chat actually reads a new question and answers it in the customer's language. Prices follow the same ladder, from a platform fee of a few hundred baht a month to AI tiers from 990 to 3,900 baht a month.
The three families of chat software
Almost every product on the market is one of three things, and vendors blur the labels because the expensive one sounds like the cheap one when you read the headline.
The three run on the same surface: chat apps your customers already open. In Thailand that surface is overwhelmingly LINE, with about 56 million monthly users, roughly 78% of the population, and 62%+ of Thai online shoppers who find and buy through chat apps.
- Auto-reply: echoes the keyword answers you configured yourself
- Rule-based chatbot: walks a flow you script, step by step
- AI chat: reads a new question and answers from your content
Type 1: keyword auto-replies on LINE
The entry point. You define keywords and canned answers inside your LINE Official Account: send price, get the price card; send open, get the hours. Everything else falls back to a human.
It costs almost nothing to start: LINE's own official account packages run from about 555 baht a month for the basic chat tier and about 1,280 baht a month for the next one, plus VAT. The limits show up fast: the moment a guest writes a sentence you did not anticipate, the system has nothing to say, and the conversation waits until you personally read it.
- Platform cost: LINE official account from about 555 baht a month plus VAT
- Answers only what you pre-configured, word for keyword
- Every novel question still waits for a human
Type 2: rule-based chatbots
A rule-based chatbot is a flowchart with a chat window: menus, branches, conditions, handoff at the end. Book a table, press 1; price list, press 2. Done properly it handles a surprising share of daily traffic, and it never improvises, which is also its weakness: anything outside the script becomes a dead end.
Development is quoted per project according to flow complexity, and then somebody has to maintain the rules every time a price or a policy changes. For stable, repetitive journeys this is solid engineering; for open-ended questions it is scaffolding.
- Great for fixed journeys: bookings, menus, opening hours
- Priced per project by complexity, maintained by hand afterwards
- Breaks the moment the customer asks something off-script
Type 3: AI chat that answers like a person
An AI agent is trained on your content, catalog, FAQs and tone, then answers questions you never wrote a rule for. Ours, Nisa, runs on your website and your LINE Official Account, replies in Thai, English or French in the customer's own language, captures the lead or the booking, and hands off to your team when a human is needed.
The price ladder is published: Support at 990 baht a month for 24/7 answers, Booking at 1,990 baht a month to capture appointments, Sales at 3,900 baht a month to recommend and take orders, plus a one-time setup and training of 2,900 baht, free on annual plans. AI usage is included under fair use. Details sit on our AI chatbot page.
- Answers questions you never programmed, in the customer's language
- 990 to 3,900 baht a month depending on the outcome you want
- One-time setup of 2,900 baht, free on annual plans
Comparing the real monthly cost
Put the three on one line. Auto-reply: a few hundred baht a month for the platform, zero brain, your time as the maintenance cost. Rule-based: a development bill up front, platform fee on top, and recurring edits whenever reality changes. AI: one monthly price covering the brain, the tuning and the multilingual answers, with the platform fee paid separately to LINE either way.
The hidden variable is your own time. The cheap option is only cheap if somebody on your team answers the leftover conversations, and Thai customers who get no answer at 11 p.m. simply go to the competitor who did.
- Auto-reply: cheapest bill, but your team is the fallback
- Rule-based: upfront build plus manual rule maintenance forever
- AI: one published price, platform fee to LINE on top
Checklist: how to choose
Run any vendor through five questions and the right shape of answer becomes obvious. What percentage of your messages are repeats, do you need to capture bookings or just answer, does it have to work after hours, does it need Thai and English, and who owns the transcripts when you leave.
If most messages are four repeated questions, start with auto-replies and graduate when the repetition annoys you. If you lose count of overnight enquiries, the AI tier pays for itself before the month ends.
- What share of messages are repeats?
- Do you need bookings and lead capture, or answers only?
- Who owns the conversation data if you cancel?
Frequently asked questions
What is customer chat software?
Any tool that answers customer messages automatically. In Thailand the three main types are keyword auto-replies inside LINE, rule-based chatbots that walk scripted flows, and AI chat trained on your own content that answers questions you never programmed.
How much does customer chat software cost?
LINE official account platform fees start around 555 baht a month plus VAT. AI tiers that actually answer from your content run 990 to 3,900 baht a month with a one-time setup of 2,900 baht. Full numbers are in our LINE chatbot price guide.
What is the difference between a chatbot and AI chat?
A rule-based chatbot executes flows somebody scripted in advance and stops at anything off-script. AI chat reads a new question and answers from your content, which is why it handles the long tail of questions nobody predicted.
Do I need a chatbot for a small shop?
If the same four questions come in daily and you ever miss messages after hours, yes. Start simple with keyword auto-replies and move to AI once repetition or overnight enquiries start costing you customers.
Does it have to work on LINE?
In Thailand that is where your customers already are, so LINE should be the first channel. The best setup runs the same brain on your website widget and your LINE official account, so answers stay identical in both places.
