WhatsApp AI chatbot.
AI calling agents, too.

A WhatsApp AI chatbot replies automatically to incoming customer messages using an AI model. Wapzen uses your instructions, business documents, and FAQs to help answer support questions and respond to leads on WhatsApp, even outside office hours.

Yes. Wapzen is currently free to use, with every feature included: the WhatsApp AI chatbot, the AI voice agent for inbound and outbound WhatsApp calls, calling campaigns, knowledge bases, and API tools. You don't need a credit card, your own AI API keys, or the WhatsApp Business API, so there are no per-message fees either.

Sign up for free, create a chat agent, choose an OpenAI or Anthropic model, and write its instructions. Attach a knowledge base with your FAQs, prices, or documents, then connect your WhatsApp number by scanning a QR code. The chatbot starts replying to incoming messages right away, with no coding required.

Yes. Assign a voice agent to your connected WhatsApp number, and AI answers incoming WhatsApp voice calls automatically, day or night. The agent understands the caller, replies in a natural voice in real time, looks up answers in your knowledge base during the call, and saves every call with a transcript.

An AI calling agent is software that holds a voice conversation on its own: it listens to the caller, decides what to say with an AI model, and replies in a natural voice in real time. Wapzen's AI calling agent works over WhatsApp calls, answering inbound calls like an AI receptionist and making outbound calls for follow-ups and campaigns.

Yes. Set a voice agent to outbound (or both directions) and place calls from the dashboard, or run an outbound calling campaign: each lead you add is called on WhatsApp by your AI voice agent, and results appear in campaign analytics.

Yes. Wapzen connects your existing WhatsApp or WhatsApp Business number by QR code, the same way you link WhatsApp Web. There is no Business API application, template approval, or developer setup, and the same connection powers both the AI chatbot and AI voice calls.

Yes. The personal WhatsApp app has no built-in auto-reply, but Wapzen links a personal number the same way it links a WhatsApp Business number: by scanning a QR code. Assign a chat agent and it auto-replies to incoming messages with AI, answering each question instead of sending a fixed message.

A greeting or away message sends a preset response. Wapzen's WhatsApp AI auto-reply uses the customer's question, your instructions, and your knowledge base to generate a relevant answer. With API request tools configured, it can also look up information in your own systems.

Yes. Add your services, opening hours, and support FAQs to a knowledge base for chat and voice agents. To check live availability, book an appointment, or look up an order, configure an API request tool connected to your booking or order system. These actions require that integration to be set up.

Use a WhatsApp AI agent for customer support, receptionist calls, sales questions, and outbound follow-ups. Appointment booking and live order lookups work through API tools you connect. These workflows can help real estate teams, clinics, e-commerce stores, education providers, and local services respond to enquiries.

The chatbot replies in the language your customer writes in. For voice calls you choose the agent's language from dozens of options, including English, Arabic, Hindi, Bengali, Spanish, and French, and pick a voice that speaks it.

Yes. Add text or files such as PDFs and Word documents to a knowledge base and attach it to any chat or voice agent. You can also create API request tools, for example to check an order or book an appointment in your own system, and the agent uses them during chats and calls.

Wapzen chat agents run on OpenAI GPT models, the model family behind ChatGPT, or on Anthropic Claude models. You choose the model for each chat agent, so you can balance reply quality, speed, and cost.

The dashboard includes every WhatsApp chat conversation, call history with transcripts, and outbound campaign activity and analytics, so your team always has the context to follow up.

Wapzen is a free, no-code builder for WhatsApp AI chatbots and AI voice call agents. Connect your WhatsApp number, configure chat and voice agents with your knowledge and tools, and manage messages, inbound and outbound calls, and campaigns from one dashboard.
