WhatsApp AI Agent

A WhatsApp AI agent reads each incoming message, works out what the customer is asking, and replies in plain language using your own business information. It is not a numbered menu: customers type the way they normally would — "do you have this in blue, and can it arrive by Friday?" — and the agent answers the question they actually asked.

Every answer comes from the knowledge you give it: product lists, prices, opening hours, delivery and return policies, FAQs or your website. Neksio uses retrieval-augmented generation (RAG), so the agent looks up the relevant passage before replying instead of guessing. When the information is not there, it says so and leaves the conversation for your team rather than inventing an answer.

The agent replies in the language your customer writes in, handles several conversations at once, and keeps going at night, on weekends and on holidays — the hours when most unanswered WhatsApp enquiries are lost.

Neksio connects your number through Meta's official WhatsApp Business Cloud API using Meta's embedded sign-up flow. There is no unofficial automation and no phone left running a WhatsApp Web session, so your number is not put at risk of a ban for using a grey-market tool.

Verification by Meta usually takes a few hours to a couple of days. Once the number is live, the agent answers customers who message you inside WhatsApp's 24-hour customer-service window, and you can send pre-approved message templates when you need to start a conversation. Meta bills WhatsApp conversations under its own pricing, separately from your Neksio plan.

Neksio is a reply tool, not a bulk or broadcast messaging service: it is built to answer the customers who come to you, which is what keeps a WhatsApp Business account healthy over time.

Some conversations should end with a human — a complaint, a large order, a customer who simply asks for one. Every WhatsApp conversation shows up in the Neksio inbox, and you can take over at any point and reply yourself. With the Neksio Android app, you get an alert when a customer needs a person and can step in from your phone in one tap.

Each question the agent could not answer is also a signal: add the missing information to your knowledge base and the agent handles that question on its own next time. Over the first few weeks, the share of conversations that need a person tends to fall as the knowledge base fills in.

You can build and run a WhatsApp AI agent on Neksio's Free plan with 100 AI replies a month and no credit card. Starter ($8.99/month) raises that to 5,000 replies and trains the agent on your full knowledge base, including your website. Growth ($11.99/month) adds Facebook, Instagram and TikTok to the same agent, and Scale ($29.99/month) gives unlimited replies with your own OpenAI key and multiple WhatsApp numbers for multi-branch businesses.
