How to Build a WhatsApp AI Agent Free: Step-by-Step Setup Guide
2026-11-05
You can set up a free AI agent on WhatsApp without writing code, but only if your business qualifies. Meta's built-in AI replies to customers about hours, products, prices and shipping, and hands chats to you when needed. It is free to start, with a monthly response allowance. This guide covers who can use it, the setup steps, what it costs, and what to check before going live.
Key Takeaways
Meta's WhatsApp AI agent (called "business AI" in WhatsApp's help center and "Meta Business Agent" in other coverage) is free to start, with a monthly response allowance in the WhatsApp Business app. Extra responses need a paid Meta One plan, and businesses on the WhatsApp Business Platform pay per usage.
Availability is limited. WhatsApp's help page says the feature is "currently only available in limited countries to select businesses," supports only English and Spanish, and favors businesses with a product catalog that run Facebook or Instagram ads leading to WhatsApp.
Setup takes a few taps, but the agent writes its own replies, so Meta warns some may be inaccurate. Test before launch, review chats regularly, and know how to pause it.
What Is a WhatsApp AI Agent?
A WhatsApp AI agent is an AI assistant that answers customer messages on a business's behalf. Meta's version replies in the chat using your catalog, business description, address and hours. Per the sources reviewed, it can:
Answer questions about hours, location, products, prices, discounts, payment and shipping
Recommend products from your catalog
Book appointments and qualify leads (per Metricool's description)
Guide a customer toward a purchase inside the chat
Hand the conversation to a human, after which the AI stops replying
Tell customers they are chatting with an AI
It only responds when a customer messages first. It does not start conversations.
Can You Build One for Free? What It Costs
Yes, to start. Here is the pricing picture as described by Metricool:
WhatsApp's own help page does not mention pricing, so confirm current terms in your app before relying on the free tier.
Who Can Use It? Check Eligibility First
Eligibility is the biggest catch. According to WhatsApp's help center:
It is "currently only available in limited countries to select businesses."
Eligible examples include businesses that run Facebook or Instagram ads that open a WhatsApp chat and that have a product catalog.
Only English and Spanish are supported, and the language follows your business phone number.
Metricool's overview describes a broader rollout across WhatsApp, Messenger, websites and, gradually, Instagram. The two sources differ in tone, so treat WhatsApp's own page as the authority for your account. If you don't see the option, you likely don't have access yet.
Step-by-Step: How to Set Up Your WhatsApp AI Agent
No coding is required. The steps below combine WhatsApp's help page and Metricool's walkthrough. Menu labels may differ ("Business AI" vs. "Meta Business Agent") depending on your rollout.
Use the WhatsApp Business app. The consumer WhatsApp app doesn't have the feature.
Complete your business profile. Add your description, address, hours and a product catalog, since the AI draws on this information.
Open the AI setting. Go to Tools and choose Business AI (or Meta Business Agent), then follow the prompts. If you don't see it, your account isn't eligible yet.
Let it learn. The agent can learn from your chats, catalog, FAQs, website and social posts.
Set the rules. You can set business information, tone and instructions, audiences, and handoff rules.
Test it. Send sample questions and review the replies before going live.
Turn it on. You can also enable it for a single chat through the AI replies option, or through Meta Business Suite by scanning the QR code Facebook Business Account sends you.
To turn it off, open Tools > Business AI, tap Disconnect AI, and confirm. Larger businesses can use the Meta Business Agent Platform to connect tools such as Shopify and Zendesk.
What to Know Before You Go Live
Several details affect how the agent behaves:
Manual replies pause the AI. If you answer a chat yourself, AI responses stop until you unmute it.
Customers are told. They are notified the first time they chat with an AI-enabled business.
Meta collects chats. Meta collects messages from AI-enabled chats to improve its AI, even when muted. Disconnecting stops future sharing. Consider this before enabling it for sensitive conversations.
Some features change. Enabling it may affect broadcast lists, disappearing messages, and message editing and deletion. Disconnecting restores them.
Replies can be wrong. The AI writes each reply itself, and Meta says some may be inaccurate or inappropriate.
Pre-launch checklist
Is your catalog, pricing, and hours accurate and up to date?
Have you tested refund, shipping and complaint questions?
Do you know how to hand off to a human quickly?
Are you comfortable with Meta collecting these chats?
Do you have a weekly habit of reviewing transcripts?
Limits: What the Free Agent Can't Do
It works on WhatsApp, Messenger, your website, and (soon) Instagram. Email, SMS and platforms like TikTok are handled separately.
It replies to incoming messages only. It does not start chats from comments or Story replies.
Language is limited to English and Spanish on WhatsApp, per the help page.
It isn't a substitute for human support on disputes or high-value decisions.
Building AI Agents Beyond WhatsApp
A built-in WhatsApp agent is one kind of AI agent: it follows your instructions inside one app. Other agents connect to data and tools, such as trading and research. If you want to understand the broader approach, Bitrue's guides on how to build AI agents without coding and how to build an AI trading agent</a> cover the same ideas of goals, data, rules and testing.
