🤖 Key Features

An AI assistant that knows your business — and knows when to call your team

Your WhatsApp Business number, answering customers 24/7 — from your own knowledge.

🤖

Answers 24/7 in seconds

Customers get a reply in about 1–3 seconds, day or night, weekends and public holidays.

📚

Answers only from your knowledge

The AI replies using the products, prices and FAQs you enter. If the answer isn’t there, it sends your own “our team will get back to you” message instead of guessing.

🌏

English, Malay & 中文

Replies in the language the customer writes in — or fix one language if you prefer.

🗂

Multiple topics, automatic menu

Create separate knowledge bases for each product or department. Customers who say “Hi” get a numbered menu built from your topics.

🙋

Smooth handoff to your team

Customers can choose “Talk to our team” or type words like “agent” or “staff”. The AI stops and your team continues in the BulkSMS Conversation inbox.

⏸

AI steps back when staff reply

When your staff answer a customer, the AI pauses for that customer for a period you choose, so it never talks over your team.

↩

Customer can return to the menu

Typing “MENU” (or “EXIT”, “0”) brings the AI menu back at any time.

🕘

AI working hours

Run the AI 24 hours, or only at set hours, with a custom “outside hours” message.

🧪

Test before going live

A built-in simulator lets you chat with your AI in the portal. Nothing is sent to customers.

📊

Reply log & “couldn’t answer” list

See every question and answer. A list of questions the AI couldn’t answer shows you exactly what to add next.

🚀

Ready-made starter kit

Start from sample topics and FAQ templates, fill in your details, and switch on. Bulk import FAQs from a CSV file.

💬

Short, WhatsApp-friendly answers

One clear message per question, with bold text and lists where helpful. “OK” and “thanks” messages don’t trigger a reply.

💬 How It Works

What your customer experiences

Answers in seconds. Only from your information. Your team always in control.

  1. 1

    Customer says hi

    The AI sends your greeting with a numbered menu of your topics (e.g. 1. Products & pricing · 2. Support · 3. General info · 4. Talk to our team).

  2. 2

    Customer picks a topic — or just asks

    e.g. “How much is the Pro plan?” — no need to pick from the menu first.

  3. 3

    AI answers from your information

    In a few seconds, in the customer’s language.

  4. 4

    Not in your information?

    The customer gets your fallback message (e.g. “Our team will get back to you shortly”), and the question appears in your “couldn’t answer” list.

  5. 5

    Wants a person?

    They choose “Talk to our team” or type “agent”. The AI stops and your team takes over. The customer can type “MENU” to return to the AI.

💡 Several quick messages sent together (“hi” … “price?” … “for 2 units”) are read together and answered once.
⚙️ Set Up

Set up in minutes, in 5 steps

Everything happens in your BulkSMS portal — start from a ready-made sample and fill in your details. No coding.

Requirement: a WhatsApp Business API number with BulkSMS. AI Reply is activated for your number by the BulkSMS team — ask us via WhatsApp or the Contact page. The number then shows the 🤖 AI Reply menu in your portal.
STEP 1

Create your knowledge

Add topics (e.g. Products, Support, General) and entries: questions & answers, price lists, policies. Start from the sample starter kit or import FAQs from a CSV file.

STEP 2

Set your messages

Business name, greeting/menu, fallback message, handoff message, optional AI hours and outside-hours message, reply language.

STEP 3

Test

Chat with your AI in the Test AI page and see which information it used. Adjust entries until the answers look right.

STEP 4

Switch on

Turn AI Reply ON. Incoming WhatsApp messages are answered from then on.

STEP 5

Improve

Check the AI Reply Log weekly. Add answers for questions it couldn’t answer.

🛡 Built-in checks prevent switching on an empty or unfinished setup — sample entries that still contain placeholder text are skipped until filled in.

🛡 Control & Safety

You stay in control

Worried the AI will say something wrong? It is built to answer only what you have told it.

  • Knowledge-based answers: the AI is configured to use your knowledge base and send your fallback message when it cannot find an answer. Test your content before switching it on and review the reply log regularly.
  • Stays on topic: questions unrelated to your business (recipes, homework, general trivia) are politely not answered.
  • Business-focused safeguards: the AI is configured to stay within your business information and disregard requests to change its instructions.
  • Your team is always in control: handoff on request, automatic pause when staff reply, switch the AI off any time.
  • Full visibility: every AI answer is logged and viewable in your portal.
  • Fair-use safeguards: built-in limits per contact and per day stop runaway conversations.
  • Minimal data use: for each question the AI receives only the few relevant entries from your knowledge base, not your whole database.
PricingNo extra
AI fee.

Each AI reply is sent as a normal WhatsApp service message and charged per message at your usual service rate. The AI itself is included. (Under our platform billing, inbound customer messages are billed once per 24-hour session. Confirm the applicable SGD rates with our team.) Greetings, menu replies and handoff messages are also one message each. Messages like “ok” or “thanks” don’t trigger a reply.

ℹ Good to Know

What AI Reply does not do

  • Does not look up live data such as order status, account balances or stock levels on its own.
  • Does not make bookings or take payments by itself. It can share your booking or payment link if you put it in the knowledge base.
  • Does not send marketing broadcasts — AI Reply only answers incoming messages. Broadcasts use WhatsApp templates as today.
  • Works with WhatsApp Business API numbers on BulkSMS — not with the free WhatsApp Business mobile app or numbers hosted with another provider.
  • Not a replacement for your team on complex or sensitive cases — those are handed over.

❓ FAQ

WhatsApp AI Reply — questions answered

What is WhatsApp AI Reply?
An AI assistant for your WhatsApp Business API number. It answers customer messages automatically, 24/7, using the product, price and FAQ information you provide in the BulkSMS portal.
Do I need any coding or technical skills?
No. Everything is set up in your BulkSMS portal: fill in your information, test, and switch on. Our team can help if you prefer.
How much does it cost?
There is no extra AI fee. Each AI reply is charged as one outbound WhatsApp service message at your normal rate. "OK" and "thanks" messages don't get a reply, so there is no outbound reply charge. Under our platform billing, inbound customer messages are billed once per 24-hour session. Confirm the applicable SGD rates with our team.
Will the AI make up answers or prices?
It is configured to answer from the information you give it and use your fallback message when it cannot find an answer. Test the knowledge base and review the reply log to check accuracy and add missing answers.
Which languages does it support?
English, Malay and Chinese. By default it replies in the customer's language; you can also fix one language.
How does a customer reach a real person?
By choosing "Talk to our team" in the menu, or typing words like "agent", "staff" or "human" (you can add your own). The AI stops for that customer and your team continues in the Conversation inbox. The customer can type "MENU" to return to the AI.
What happens when my staff reply to a customer?
The AI automatically pauses for that customer for a number of hours you choose, so it won't interrupt your staff.
What if a customer asks something unrelated, like a recipe or homework?
The AI only helps with your business. Unrelated questions get your fallback message.
Can I control when the AI works?
Yes. Run it 24 hours or set working hours, with an optional message for outside those hours. You can switch it off at any time.
Can I test it before customers see it?
Yes. The Test AI page lets you chat with your AI inside the portal. Nothing is sent to WhatsApp.
How do I teach the AI about my business?
Add knowledge bases (topics) and entries — questions and answers, price lists, policies. Start from the ready-made sample, or import many FAQs at once from a CSV file.
Can I have different topics or departments?
Yes. Each knowledge base becomes an option in the customer menu, and the AI searches the right topic for each question.
Can it check order status or book appointments?
Not by itself — it answers from your knowledge base. It can share your booking or tracking link. For live order status or bookings inside WhatsApp, ask us about a WhatsApp Automation Flow built by our team.
Where can I see what the AI said?
In the Conversation inbox and in the AI Reply Log, which shows every question, answer and result, plus a list of questions the AI couldn't answer.
Does it work with my current WhatsApp number?
It works with WhatsApp Business API numbers on BulkSMS. If you use the WhatsApp Business app or another provider today, talk to us about moving your number to the WhatsApp Business API with BulkSMS.
