How to make a WhatsApp chatbot for free.
Five steps, no code.
Sign up for free
Create a Wapzen account. There is no credit card to enter and no WhatsApp Business API application to file.
Create a chat agent
Name your chatbot, choose an OpenAI GPT or Anthropic Claude model, and write its instructions: who it speaks for, its tone, and what it should or shouldn't answer.
Add your business knowledge
Attach a knowledge base with your FAQs, prices, opening hours, or policies. Paste text or upload PDF and Word files, and the chatbot answers from them.
Connect your WhatsApp number
Scan a QR code with WhatsApp on your phone, the same way you link WhatsApp Web. It works with a personal WhatsApp or a WhatsApp Business number.
Test it and go live
Message your number from another phone. The AI chatbot replies right away, and every conversation is saved in your dashboard.
What your free chatbot does.
Everything, included.
The free plan is the full product. Every feature below works on your own WhatsApp number from day one.
Answers from your knowledge
Uses your documents, FAQs, and prices, so answers are specific to your business instead of generic.
Your customer's language
Customers write in their own language and the chatbot answers in the same one.
Actions with API tools
Connect API request tools to check an order, look up availability, or book an appointment in your own system.
Your existing number
Link a personal WhatsApp or WhatsApp Business number by QR code. No new number, no Business API.
Saved conversations
Review every chat in the dashboard, so your team can follow up with full context.

There are three common ways to automate WhatsApp replies without paying for a chatbot platform. Here's how they differ.
| WhatsApp Business app | DIY with n8n or code | Wapzen | |
|---|---|---|---|
| Cost | Free | Free software; you pay for hosting and AI usage | Free right now |
| AI answers | No: fixed greeting and away messages | Yes, if you build it | Yes |
| Coding or setup | None | Workflows, hosting, and API setup | None |
| WhatsApp connection | Business app only | Usually the Business API | QR code, personal or Business number |
| Answers calls with AI | No | Rarely | Yes, with a voice agent |

Your questions, answered.
Is a WhatsApp chatbot free?
It can be. The WhatsApp Business app's greeting and away messages are free, but they send fixed text. Wapzen is currently free and gives you a real AI chatbot that answers each question from your business information.
How do I make a WhatsApp chatbot for free?
Sign up for Wapzen, create a chat agent with your instructions, attach your FAQs or documents, and connect your WhatsApp number by scanning a QR code. The chatbot then replies to incoming messages, with no coding and no cost.
Can I create a WhatsApp chatbot without coding?
Yes. Wapzen is a no-code WhatsApp chatbot builder. You set up the chatbot with plain-language instructions and your own documents instead of flow diagrams or code.
Do I need the WhatsApp Business API for a chatbot?
Not with Wapzen. It links your number by QR code, like WhatsApp Web, so there is no Business API application, template approval, or per-message fee.
Does it work with a personal WhatsApp account?
Yes. You can link a personal WhatsApp or a WhatsApp Business number. The personal app has no built-in auto-reply, and Wapzen adds AI auto-reply to it.
Which AI powers the chatbot?
You choose for each chat agent: OpenAI GPT models, the model family behind ChatGPT, or Anthropic Claude models. Both are included, so you don't need your own API key.
Can the chatbot also answer WhatsApp calls?
Chat agents handle messages. For calls, create a free AI voice agent in the same account: it answers inbound WhatsApp calls in a natural voice and can make outbound calls.
