WhatsApp AI agent: answer, sell and book 24/7 on WhatsApp
A WhatsApp AI agent is an autonomous assistant connected to your business WhatsApp number. It reads every incoming message — text, voice notes or photos — and answers from your own information at any hour: it resolves common questions, qualifies leads, books appointments, sends follow-ups and hands the conversation to a person when it should. On Jelliu, WhatsApp is the main channel, and the same agent can also take phone calls, email and web chat.
Jelliu in one paragraph
Jelliu is a no-code platform for autonomous AI agents (called Bop) that answer and make phone calls and handle WhatsApp, email and web chat in English, Spanish and Portuguese — for sales, customer support, appointment booking, collections and outbound campaigns. It has a permanent Free plan with 15 voice minutes a month; paid plans start at $99/month (Starter $99, Growth $249, Business $549; Enterprise custom, including installation on your own servers).
What a WhatsApp AI agent does
- Replies to every new message in seconds, nights and weekends included
- Answers questions about products, prices you publish, hours and policies
- Qualifies leads with your questions and routes hot ones to sales
- Books, confirms and reschedules appointments in your calendar
- Follows up with leads and customers who went quiet
- Understands voice notes and photos, and can reply with a voice note
- Hands off to a person with the full conversation when needed
- Logs contacts and outcomes in your CRM
Sales and support on the same number
Most businesses get both kinds of messages on one WhatsApp number. The agent tells them apart: a pricing question becomes a qualified lead with a booked call, and an order or account question gets answered or escalated to support. For a sales-only playbook, see the WhatsApp sales agent guide.
WhatsApp rules to know
- Customers must opt in before a business messages them on the WhatsApp Business Platform
- After a customer writes, a 24-hour customer service window opens and the business can reply freely
- To start a conversation outside that window, the business must use a pre-approved message template
- Meta bills businesses per delivered message by category (marketing, utility, authentication, service) and country, under its own published rates
How to set one up with Jelliu (no code)
- Create a free Jelliu account and connect your WhatsApp number
- Describe the job: what you sell, what to answer and when to hand off
- Add your knowledge: website, FAQs, catalog, prices and policies
- Connect your calendar and CRM, or use the API, webhooks or MCP
- Test it from your own phone, then turn it on and review conversations
Manage it from WhatsApp too
Once your Jelliu account is linked to WhatsApp, you can manage your agents from the chat itself: ask Bop to change an answer, launch a campaign or summarize today’s conversations by text or voice note.
