An away message sends the same text to everyone. An AI auto-reply reads the question and writes an answer from what you told it about your business. That makes it useful for the questions you get every day, and it is also why it needs more setup than a fixed reply.
This guide describes what the feature does and what you control. It does not give an accuracy figure, because any such number would depend on your own knowledge base and your own customers. The way to know how it behaves for you is to test it with your real questions, which is covered below.
AI auto-reply, away message and chatbot flow: which one is which
- 1
Away messagea fixed reply
Sends one text, usually outside working hours. Good for "we open at 10 AM". See the [away message guide](/blog/whatsapp-out-of-office-message).
- 2
Chatbot flowa fixed path
Walks the customer through buttons and steps you designed. Good for collecting details in a set order.
- 3
AI auto-replya written answer
Reads the question and answers from your business description and knowledge base. Good for open questions you cannot predict.
Most teams use more than one. A flow can collect a budget or a product name, an away message covers closed hours, and the AI answers the questions in between. The difference between a flow and an AI agent is covered in chatbot vs AI agent.
What you set up
The assistant knows only what you give it, so the setup is the product. You provide:
- A business description. What you sell, where and to whom, in plain words.
- Rules. Instructions such as "never quote a final price" or "always offer a site visit".
- A fallback message. What it says when it has no answer, for example "Let me connect you with our team."
- Knowledge base entries. Short entries for hours, prices, locations, payment options and policies.
- Hand-over words. Terms such as agent, human, complaint or refund that bring a person into the chat.
The step-by-step guide to writing these is in how to train a WhatsApp AI auto-reply, and the Help Center covers the screens in AI auto-reply setup and knowledge base and hand-over.
What happens when it does not know the answer
A model that has no answer can still produce a confident-sounding one. That is the main risk of any AI reply, and the setup above is how you reduce it: when the information is not in your knowledge base, the assistant is set up to use your fallback message or hand the chat to your team instead of making something up. Complaints and special cases belong with a person, so list the words that should bring one in.
Hand-over lands in the shared inbox, where the chat gets an owner like any other conversation. Nothing about the AI changes how your team works there.
What it cannot do for you
- It cannot promise accuracy. Its answers can be only as good as the knowledge base you write and keep up to date. Check prices, hours and policies whenever they change.
- It does not replace your team. Negotiation, complaints, refunds and anything sensitive should reach a person.
- It follows WhatsApp's rules. Free-form replies can be sent inside the 24-hour customer service window, and templates are needed outside it. The AI does not change that. See the 24-hour window.
- It is not set and forget. In the first week, read the chats it handled every day and fix the entries behind any weak answer.
Privacy: what is masked before a message reaches an AI provider
Before a message is sent to an AI provider, emails, phone numbers, PAN, Aadhaar, card numbers, UPI IDs and IP addresses are masked. Other personal details written in the message text, such as a customer's name, are not masked. If you do not want a kind of detail processed by an AI provider, do not invite it in your replies and tell your team how to handle it.
What it costs to run
AI auto-reply is available on Starter and above. It uses AI message packs, which are one-time purchases and do not expire; your pack credits are used first. The pricing page lists the current packs and what each includes, and we do not repeat prices here so they cannot go out of date: see Responseify pricing.
There is an optional setting to charge your wallet for each further reply when the packs run out. It is off by default. If it is off, or the wallet cannot cover a reply, AI auto-reply switches itself off and the account owner is notified, and it stays off until a pack is bought or the wallet is topped up. WhatsApp message charges are a separate matter: Meta decides which messages are charged and at what rate, and bills your own WhatsApp Business account.

If you are still choosing a platform, the AI auto-reply feature page shows the pack options, and the list of WhatsApp Business API providers in India compares what each provider publishes about AI and add-ons.

Frequently asked questions
Is a WhatsApp AI auto-reply the same as a chatbot?
No. A chatbot flow follows a path you designed with buttons and steps. An AI auto-reply writes an answer to the customer's own words from your business description and knowledge base. Many teams use both.
Can the AI hand a chat to my team?
Yes. You choose the words that bring a person into the chat, and you set a fallback message for questions the knowledge base does not cover. The chat then sits in your shared inbox like any other.
Will it always give the right answer?
No tool can promise that. The answers depend on what is in your knowledge base, so test it with real questions before you turn it on, read the chats in the first week and correct the entries behind any weak answer.
Does AI auto-reply work on the Free plan?
No. It is available on Starter and above, and it runs on AI message packs that you buy once and that do not expire.
Is customer data sent to an AI provider?
Message text is sent to an AI provider to write the reply. Emails, phone numbers, PAN, Aadhaar, card numbers, UPI IDs and IP addresses are masked first. Other details, such as names, are not masked.
