Questions About Building an AI Agent
How the free plan works, what Premium adds, how WhatsApp, Facebook and Instagram connect, and what happens to your data.
Getting started
Yes. Building and launching an AI agent for WhatsApp, Facebook, and Instagram is completely free — no credit card required. Your free agent can handle customer sales and support conversations 24/7. Premium is only needed for extra features like Google Reviews management, Shopify integration, and WhatsApp bulk messaging.
No. Neksio is a fully no-code platform. You build your agent visually, upload your business knowledge (documents, FAQs, product info), connect your WhatsApp, Facebook, or Instagram account, and go live — no developers needed.
Minutes, not weeks. Sign up free, create your agent in the no-code builder, connect a channel, and start chatting. Connecting the official WhatsApp Business API can take slightly longer depending on Meta's verification, but Facebook and Instagram agents can be live almost immediately.
At platform.neksio.com. You sign up free, complete a short profile setup, then use the visual builder to create your agent, upload your business knowledge, and connect a channel. Everything happens in the browser — there is nothing to install.
A Facebook Business account for the channel you want to connect, and whatever business knowledge you want the agent to answer from — a product list, FAQs, policy documents, or a website. You can start with a single document and add more later.
Channels and setup
WhatsApp, Facebook Messenger, and Instagram direct messages. All three run through Meta's official Business Cloud API, so your account stays compliant and your messages are not at risk from unofficial automation.
Through Meta's embedded sign-up flow, which Neksio walks you through step by step. You connect your Facebook Page, select or register the phone number you want to use, and Meta verifies it. The documentation covers the whole flow with screenshots.
Usually a few hours to a couple of days, depending on Meta's review of your business. Facebook Messenger and Instagram agents do not go through this step and can go live almost immediately, so many businesses start there while WhatsApp is being verified.
Yes. You train the agent once on your business knowledge and connect whichever channels you want. Conversations from all of them arrive in a single unified inbox, so your team does not have to watch three apps.
Yes. Every conversation is visible in the unified inbox, and you can step in and reply as a human at any point. The agent hands off rather than blocking you out.
How the AI works
Your free agent answers customer questions, recommends products, handles sales conversations, and resolves support requests across WhatsApp, Facebook Messenger, and Instagram DMs. It uses RAG technology to answer accurately from your own business data, and all conversations land in one unified inbox.
RAG stands for retrieval-augmented generation. Instead of relying on what a language model happens to know, the agent retrieves the relevant passage from your own uploaded business data and answers from that. It is the difference between an agent that guesses your return policy and one that quotes it.
It says so rather than inventing an answer, and the conversation stays in your inbox for a human to pick up. Adding the missing information to your knowledge base means the agent handles that question itself next time.
The agent replies in the language your customer writes in, and answers from whatever language your business knowledge is written in. If you serve customers in more than one language, upload your knowledge base in each.
Pricing and plans
Premium unlocks everything in Free, plus: the Google Review Agent to monitor and auto-respond to reviews, Shopify integration so your agent can recommend products and create orders in chat, WhatsApp bulk messaging for broadcast campaigns, conversation and comments analysis, and priority support.
There is no trial and no time limit, because the core plan is free rather than a trial of a paid one. You can build and run an agent on WhatsApp, Facebook, and Instagram for as long as you like without paying.
No. You only enter payment details if you choose to upgrade to Premium.
Yes, at any time. Your agent keeps running on the free plan; you lose the Premium features — Google Reviews, Shopify, bulk messaging, and conversation analysis — and keep everything else.
Meta bills conversations on the WhatsApp Business Platform under its own pricing, separately from Neksio. This applies to any provider using the official API, and it is worth checking Meta's current rates for your country before you run large broadcast campaigns.
Data and privacy
Your business knowledge is used to answer your customers' questions on your channels, and is not shared with other Neksio customers. Full detail is in our privacy policy.
Yes. You can remove documents from your knowledge base at any time, and request deletion of your account and its data by contacting support.
Still stuck?
The fastest answer is usually to build an agent and see it work — the free plan takes minutes and needs no card. If you would rather ask a person first, we reply within one business day.
