AI agent for customer service: answers right away and hands you what needs a person

Quick answer

What does an AI agent for customer service do?

An AI agent for customer service answers the customer right away, by text or audio, with the company's prices, hours and rules. What it doesn't know, it hands off to a person with a summary of the conversation. At CertuAI it answers on WhatsApp, Instagram Direct and Messenger, and logs every conversation in the CRM.

A customer waiting for a reply buys from whoever answered first. The agent answers right away, with your company's information, and hands a person the conversation that needs a decision.

What changes in customer service

The gain isn't answering nicely. It's not leaving anyone waiting.

01

Instant reply

Day, night and weekends. Whoever writes at ten at night gets the answer at ten at night.

02

Text and audio

The customer speaks their own way. The agent understands the audio and answers what was asked.

03

Hands off to a person with a summary

When the topic goes beyond what it learned, the conversation goes to a person already carrying what was said.

04

History of each customer

Someone who comes back after a week doesn't start from zero. The earlier conversation is in the CRM.

How to put the agent on customer service

Three steps, and none of them is designing a flow.

  1. Teach the business to the Brain

    Services, prices, hours, rules and what you would rather nobody answer. The Brain is the knowledge base that makes the agent answer like your company, and not like a generic robot.

  2. Connect the number you already use

    By QR code or through Meta's official signup. CertuAI is a Tech Provider of the Meta WhatsApp Business Platform, and the number stays yours: the plan gives you the connection slot, not a new number.

  3. Follow along in the CRM and take over whenever you want

    Each conversation shows up in the dashboard with a contact, a deal and a task. You step into the same conversation at any time, and the agent hands the topic back to you when it falls outside what it learned.

What the agent answers and what stays with the team

The split is yours. This is the one that works best to start.

Automated customer service that doesn't feel like a robot

What annoys customers about automated service is the menu: press 1, press 2, invalid option. The AI agent has no menu. The person writes what they want and gets an answer to that.

The answer comes from the Brain, which is where your company's information lives. That is why it speaks your prices and your rules, not an average from the internet. You read the conversations, fix what came out off by writing the correction and take over any conversation whenever you want.

Frequently asked questions

Does the AI agent replace the customer service team?

It takes the repeated questions and after-hours service off the team. What needs a decision, like a complaint or a negotiation, stays with people, who receive the conversation with the summary.

Which channels does the agent cover?

WhatsApp, Instagram Direct and Messenger, in the same dashboard. All three channels come with Start, Pro and Max.

What if the agent doesn't know the answer?

It doesn't make anything up. It hands the conversation to a person and notifies the person in charge. The new question can become information in the Brain, and next time it answers.

How much does an AI agent for customer service cost?

At CertuAI, from US$ 75 per month on Start, with 1,600 AI replies and 5 team members in the dashboard.
