Independent audits of chatbot total cost of ownership over a 12-month period commonly find that actual spend runs two to three times the advertised subscription price, once setup, integrations, overage and onboarding are added in. That gap is where most Hong Kong AI chatbot budgets go wrong.
So this page does the opposite of a pitch. It publishes the numbers, the limits and the places where a different product is the better buy.
How much does UD AI Chatbot Master cost?
AI Chatbot Master is priced on four published tiers. Startup is HK$298 per month, Standard is HK$498 per month, Professional is HK$988 per month, and Enterprise is custom-quoted. All tiers require a minimum six-month subscription, and setup is billed separately as a one-off fee on the lower tiers.
Here is the full picture, taken directly from the published pricing table.
--- Startup, HK$298 per month. 1,000 conversations per month, 1,000-page knowledge base, one-off setup fee of HK$1,000, 30 days of chat history.
--- Standard, HK$498 per month. 10,000 conversations per month, 5,000-page knowledge base, one-off setup fee of HK$3,000 which is waived on a yearly subscription, 90 days of chat history.
--- Professional, HK$988 per month. 50,000 conversations per month, 20,000-page knowledge base, one-off setup fee of HK$3,000 which is waived on a yearly subscription, 180 days of chat history.
--- Enterprise, custom pricing. Custom conversation volume, custom knowledge base size, setup fee waived, custom chat history retention.
Every tier includes website chatbot, WhatsApp and Facebook Messenger channels, chat history, a real-time dashboard, and support for more than 90 languages.
What is the real first-year total, not the monthly price?
The monthly figure is not the number to put in a budget paper. Setup fees, the six-month minimum term and the yearly-subscription waiver change the answer materially. Two worked examples using only published terms show how much.
A 60-person professional services firm on Standard, paying monthly. HK$498 for 12 months is HK$5,976, plus the HK$3,000 one-off setup fee, giving a first-year total of HK$8,976.
The same firm on a one-year Standard subscription. The HK$3,000 setup fee is waived, and a one-year subscription includes one free month of service. That is 11 paid months at HK$498, or HK$5,478, with no setup charge. First-year total: HK$5,478.
The committed route costs HK$3,498 less in year one. That is a 39% reduction for a decision that takes one meeting.
Two more terms are worth writing into the budget line.
--- A two-year subscription includes two free months of service. On Standard that is a further HK$996 saved across the term.
--- The minimum commitment is six months on every tier. There is no true month-to-month option, so a three-month trial-and-cancel plan is not available.
Which plan does a Hong Kong enterprise actually need?
Plan choice is decided by two numbers only: monthly conversation volume and knowledge base page count. Feature access is nearly identical across tiers, so paying for a higher plan buys capacity and longer chat history, not capability.
Match your situation to the tier below.
Choose Startup if you are testing one channel with one department. 1,000 conversations a month is roughly 33 a day. That covers an internal HR policy assistant or a single low-traffic product page. It does not cover a public customer service front door for a retail chain.
Choose Standard if you are replacing first-line enquiry handling for a single business unit. 10,000 conversations a month is around 330 a day. For most Hong Kong mid-market firms running website plus WhatsApp, this is the realistic starting tier, and the 90-day chat history is the minimum useful window for spotting recurring failure patterns.
Choose Professional if you run multi-brand or multi-channel volume. 50,000 conversations a month with a 20,000-page knowledge base suits a group with several product lines or a property manager handling multiple estates. The 180-day history also matters if your service reviews run on a half-yearly cycle.
Choose Enterprise if the constraint is not volume. Custom quoting is the right path when the blocker is data residency, retention policy, SSO, procurement terms or integration with a legacy CRM, rather than conversation count.
One practical warning. Teams routinely under-forecast conversation volume because they count enquiries, not conversations. A single customer question often becomes a multi-turn conversation, and abandoned sessions still count. Take your current first-line ticket volume and plan for at least double.
How does that compare to a human service desk?
The comparison that matters to a CFO is cost per resolved conversation, not licence cost. Per 2026 industry benchmarks, AI resolution runs roughly US$0.50 to US$2 per conversation against US$5 to US$15 for a human agent. On the Standard tier at full 10,000-conversation utilisation, the licence works out at about HK$0.05 per conversation.
That number is misleadingly good, and it is worth being clear why.
Utilisation is the whole argument. At 10,000 conversations a month, Standard is HK$0.05 per conversation. At 1,000 conversations a month, the same plan is HK$0.50 per conversation, a tenfold difference for identical spend. The plan does not become cheaper as you grow; it becomes cheaper as you actually use it.
The honest comparison also has to include the work the licence does not cover. Knowledge base preparation, answer review, escalation design and monthly quality checks are internal effort.

What does AI Chatbot Master not do?
This is a knowledge-based conversational product, not an autonomous agent platform. It answers from your documents across web, WhatsApp and Messenger in over 90 languages. It is not designed to take approved transactional actions inside your core systems, and it should not be evaluated as though it were.
Four limitations are worth stating before anyone signs.
--- Answering, not acting. If your requirement is that the AI verifies a caller, updates an account and issues a refund, this is the wrong product category. That workload needs an agent platform with approved-action lists and audit trails, a distinction we set out in our explainer on enterprise agent platforms.
--- Setup is a real cost on the entry tier. Startup carries a HK$1,000 one-off setup fee that is not waived by an annual commitment, unlike the HK$3,000 fee on Standard and Professional.
--- Six-month minimum term. There is no 30-day exit. If your governance process requires a short cancellable pilot, that has to be negotiated rather than selected.
--- Chat history is capped by tier. Thirty days on Startup is short for quality review. If your compliance team expects longer retention for service records, that requirement points to Professional or Enterprise regardless of volume.
Where a different product wins: if you need a self-serve free tier to experiment this week with no commitment, the international self-serve platforms are the better first step, since real 2026 chatbot pricing starts from free and most small businesses settle between US$29 and US$99 a month. If you need an autonomous agent that acts inside core systems, a deployed agent platform is the right category. If your only requirement is WhatsApp, a WhatsApp-specific product is a narrower and often cheaper fit.
What questions should you settle before you subscribe?
Five answers turn a chatbot subscription from a hopeful purchase into a measurable one. Settle them before the contract, not after month three.
--- What is your real monthly conversation volume? Take last quarter's first-line enquiry count and double it to allow for multi-turn sessions.
--- How many pages of usable knowledge do you actually have? Usable means current and approved, not everything on the shared drive.
--- Who reviews the answers each month? Name the person, not the department.
--- What happens when the bot does not know? The escalation path is a service design decision and it belongs in writing before launch.
--- Monthly or annual commitment? On Standard, the annual route is HK$3,498 cheaper in year one. If the business case survives a year, commit.
The next step
The pricing on this page is straightforward. The decision is not, because the right answer depends on your conversation volume, your knowledge base quality, your retention requirements and whether your workflow needs the AI to answer or to act.
If those four answers are already clear, choose the tier that matches your volume and commit annually. If any of them is still uncertain, a scoping conversation costs nothing and will save you from buying the wrong tier for six months. We understand AI. We understand you. With UD by your side, AI never feels cold.
