WhatsApp calls vs a phone line.
What changes.
Most AI phone agents run on a rented phone number and bill by the minute. Wapzen's runs on WhatsApp instead. Here's the trade-off.
| Typical AI phone agent | Wapzen on WhatsApp | |
|---|---|---|
| Price | Usually per minute, plus plan fees | Free right now |
| Phone number | Rent a new number | Your existing WhatsApp number |
| Who it can call | Any phone number | Anyone on WhatsApp |
| Text messages | Often a separate tool | AI chatbot included |
| Setup | Often telephony setup or developer work | No code: link by QR code |

Your questions, answered.
Is there a free AI calling agent?
Yes. Wapzen is currently free, and that includes the AI voice agent: it answers inbound WhatsApp calls and makes outbound WhatsApp calls, with no per-minute charges.
How do I make an AI calling agent for free?
Sign up for Wapzen, create a voice agent with instructions, a language, and a voice, attach your knowledge base, and connect your WhatsApp number by QR code. Your AI agent then answers calls to that number.
Can the AI calling agent call regular phone numbers?
No. Wapzen works over WhatsApp voice calls: it answers calls to your WhatsApp number and calls people on WhatsApp. The person on the other end needs WhatsApp, but you don't need a phone line or a telephony provider.
Can I use it as an AI receptionist?
Yes. Assign the voice agent to your number and it answers every incoming WhatsApp call, shares your hours, services, and prices from your knowledge base, and saves each call with a transcript for your team.
Which languages can the AI voice agent speak?
You choose the agent's language from dozens of options, including English, Hindi, Bengali, Arabic, Spanish, and French, and pick a voice that speaks it.
Do I need an OpenAI or ElevenLabs account?
No. Speech recognition, the AI models, and the voices are included in Wapzen, so there is no separate API key or bill.
Can it call a list of leads?
Yes. Create an outbound campaign, assign a voice agent, and add leads. Each lead you add is called on WhatsApp, and the results appear in the campaign's calls and analytics.
