# AI customer service assistants: what they do and when they pay off > What an AI customer service assistant is, when it pays off, how it connects to WhatsApp and the website and what it needs to work well. [Home](https://alphaimpact.pt/en/) › [Guides](https://alphaimpact.pt/en/guias/) › AI customer service assistants Page: https://alphaimpact.pt/en/guias/assistentes-de-ia-para-atendimento · Updated: 2026-10-27 An AI assistant answers the usual questions, collects the details of a request and hands the conversation to a person when needed. It pays off when the same questions arrive every day and the team answers them one by one. ## What is an AI customer service assistant? It is a program that chats with customers in writing, on WhatsApp or on the website, using the information the company gives it: services, prices, opening hours and booking rules. Unlike a menu of fixed answers, it understands questions asked in people's own words and replies in European Portuguese. When a question goes beyond what it knows, or when the customer asks, it hands the conversation to someone on the team. ## How is it different from a fixed-answer chatbot? - A rule-based chatbot follows a script of buttons and keywords. It works for predictable questions and fails when the customer writes something differently. - An AI assistant interprets the question, checks the company's information and can carry out agreed actions, such as checking the calendar and suggesting a time. - Both need clear limits: what they can answer, what they never promise and when they hand over to a person. ## When does it pay off? - The same questions about opening hours, prices and bookings arrive every day. - Requests come in out of hours and wait until the next morning. - Before giving a price, the same details always have to be collected. - WhatsApp is already the main channel customers use. When every conversation is different and needs technical analysis, an assistant helps less. Then it is better to organise the information so the team can answer better. ## How does it connect to WhatsApp and the website? On WhatsApp, the assistant uses the official WhatsApp Business platform, with the company's number. On the website, it appears as a chat window. In both cases it can check the calendar or the catalogue, log the request in the system the company already uses and alert the team when someone needs to step in. One example is Redita, the assistant on our website: it answers only with the information we wrote, guides quote requests step by step and, when it does not know, offers to take contact details or put the visitor through to a person. The team follows everything in a back office. ## What does it need to work well? - Up-to-date information on services, prices, opening hours and policies. - Written rules on what the assistant does on its own and what always goes to a person. - Someone to review the conversations in the first few weeks and correct answers. - A connection to the right systems, so the request does not stay in the chat. ## How much does it cost? It depends on the channels (WhatsApp only or the website too), the connections to other systems and the volume of conversations, which sets the cost of using the AI model. We work with a fixed price per deliverable, written in the proposal before we start. The monthly usage cost is estimated in the same proposal. ## Frequently asked questions ### Does the assistant replace the customer service team? No. It handles the repeated questions and passes to the team what needs a person: complaints, special cases and decisions. ### Does it reply in European Portuguese? Yes. The tone and vocabulary are defined with the company and reviewed before the assistant starts replying. ### What happens when it does not know the answer? It tells the customer it is passing the conversation on and alerts the person in charge, with a summary of what has been said. ### Is the conversation data secure? The proposal sets out what data the assistant uses, where it is stored and who can access it, in line with the GDPR. ## See also - [AI assistants](https://alphaimpact.pt/en/solucoes/assistentes-de-ia) - Case [Redita](https://alphaimpact.pt/en/casos/redita) --- Alpha Impact, Lda, Lisboa, Portugal · Company no.
