AI vs Human: Who Handles Customer Support Better?
AI customer service agents are better at the repeat questions your docs already answer: they reply instantly, at any hour, to many customers at once. Human agents are better at refunds, upset customers and anything that needs judgment, so most small teams do best with both: the agent answers from the help center and hands the rest to a person with the conversation attached.
The rest of this guide covers the pros and cons of each, the numbers vendors report, Klarna's results and how to set up an agent in Wonderchat, where 80% of agents that go live do so the same day.
Quick Definition: What is an AI Customer Service Agent?
An AI customer service agent is software that answers customer questions from your own help center, docs and website, in chat and other channels. It handles the questions your content covers at any hour; questions that need judgment, or that your docs don't cover, still need a person.
The difference? AI agents work 24/7, don't take long coffee breaks, and can handle multiple customers at once.
With tools like Wonderchat, you can customize an AI agent and set it up on your website content or FAQs, so it speaks like your brand from day one.
How it Works: Setting Up an AI Agent with Wonderchat
Step 1: Sign up or log in
Go to Wonderchat.io and create your account.
Step 2: Create your AI Agent
In your Wonderchat dashboard, click on the "Create Bot" button. This opens up a pop-up screen that allows you to create a custom AI agent with just a few clicks. Pick a name, choose the tone of voice, and set up custom messages, greetings, and fallback replies.
Step 3: Customize your Agent
Then add your content: upload a PDF or connect your website so the agent can answer from your product information and FAQs.

Step 5: Monitor Performance
Use the Wonderchat dashboard to see what customers ask, and check the review inbox for the questions your docs couldn't answer: answer each one once and the agent answers it from then on.
Key Stats: AI vs Human Agents by the Numbers
In one benchmark, AI agents outscored human agents. Research using the SelfScore benchmark shows AI agents using RAG (Retrieval Augmented Generation) scored higher than humans in response helpfulness and problem-solving.
52% faster at handling customer issues, by one vendor's count. ServiceNow reports that its own AI agents cut resolution time by more than half.
Hard to tell apart, according to Salesforce. Salesforce CEO Marc Benioff said customers can't tell the difference between AI and human agents in many interactions anymore.

A Real-Life Example
Klarna's AI Customer Support
source: Klarna
Swedish fintech giant Klarna is already using AI agents to handle customer inquiries at scale. Here's what Klarna reported a month after launch:
Their AI chatbot handles two-thirds of all support chats
It replaced the work of 700 full-time agents
Average response time was reduced from 11 minutes to just under 2 minutes
Klarna expects a $40 million profit boost from switching to AI agents
CEO of Klarna, Sebastian Siemiatkowski says: "This isn't something that's happening in the future, it's happening now."
Conclusion: What's Best for Your Business
An AI agent won't replace your whole team: Wonderchat resolves about 75% of evaluated conversations without a person, and the rest still need one.
If your team is drowning in repetitive queries, an AI agent can help you deliver instant replies, 24/7. But if trust and relationship-building matter deeply to you, human agents are still your best bet.
The best setup? Consider a hybrid approach.
Deploy an AI Agent to handle routine helpdesk tasks like answering FAQs, tracking orders, providing shipping updates, and escalating to humans when needed. Wonderchat's agent answers and hands over; if you want an AI agent that issues refunds or changes orders itself, Ada, Decagon and Sierra take multi-step actions.
Example:
Use AI agents when:
Answering repetitive questions (e.g., shipping updates, account issues)
Providing support outside business hours
You’re scaling support across time zones or languages
Use human agents when:
You’re dealing with sensitive issues (e.g., refunds, angry customers)
You want to upsell or offer a personalized service to your loyal customers
You need nuanced decision-making skills
