An AI customer service agent answers what it knows and passes the rest to a person
We make Uptonica, one of the tools in this guide. Here we explain what an AI customer service agent does, how six tools charge for it, and when it should hand the conversation to your team, with where each tool falls short, ours included.
Quick answer
- What it is: an AI that answers your customers in chat, email or messaging apps, from your own information.
- What it does on its own: answers common questions, checks orders and bookings, collects details.
- What it should pass to a person: complaints, exceptions and anything it doesn’t know.
- What it costs: from about $0.75 to $1.50 per resolved question on the tools that charge that way, or a monthly allowance on the others.
What an AI customer service agent does
An AI customer service agent reads the customer’s message, finds the answer in your information (help articles, products, policies, orders) and replies in seconds, at any hour. Unlike a scripted chatbot, it doesn’t need a button for every question. The good ones know their limits: when a question is outside what they know, or the customer asks for a person, they pass the conversation to your team with what has been said so far.
How it is billed
Tools charge for the AI in three ways. Per resolved question: you pay only when the AI closes the conversation without help. Per conversation: you pay for each chat the AI takes part in, resolved or not. A monthly allowance: a number of replies or credits included in the plan. On top of that, most helpdesks charge a monthly fee per agent.
How we chose
We read the pricing pages of every tool on 15 November 2026. Prices are the cheapest plan that includes the AI agent, in US dollars or euros as each site shows. We left out Zendesk, whose pricing page we couldn’t open from our location.

Prices from each vendor’s own site, checked on 15 November 2026. A price per resolution and a price per conversation are not the same thing: compare them with how many of your conversations the AI really closes on its own.
Each tool
Intercom (Fin)
An AI agent you pay per resolved conversation, on Intercom’s helpdesk or on the one you already use. Good for: teams that want to pay only when the AI solves the question. Watch for: seats are billed separately, and WhatsApp is charged per message.
Help Scout
A shared inbox and help center with Envoy, an AI agent paid per resolution, with a monthly cap you choose. Good for: small support teams working mainly by email. Watch for: it is paid per user, and the AI is an add-on on top of the plan.
Gorgias
A helpdesk for online stores, with an AI agent on every plan that can look up and act on orders. Good for: e-commerce support teams. Watch for: above the included interactions you pay $1.50 each, and every AI interaction also counts as a ticket.
Freshdesk (Freddy)
A helpdesk with Freddy, an AI agent that answers email and chat, with 500 sessions included. Good for: support teams with several agents. Watch for: it is paid per agent, and extra AI sessions come in packs of 100.
Tidio (Lyro)
Live chat and inbox with Lyro, an AI agent sold as an add-on or on its own. Good for: small businesses starting with chat. Watch for: the AI is priced on top of the chat plan, and both count conversations.
Uptonica
AI on your website chat, WhatsApp, Instagram, Messenger, Telegram, email and the phone, from the same information. It books appointments and passes conversations to your team in the same inbox. Good for: shops, restaurants, salons and local businesses whose customers write and call. Watch for: the €59 Core plan includes one user, prices are in euros, and the free plan is only on Shopify.
When it should hand over
Hand over when it doesn’t know. An AI that guesses does more damage than one that says it will ask a colleague.
Hand over when the customer asks. If someone writes “I want to talk to a person”, the conversation should reach your team at once.
Hand over with the context. Your team should see what has been said, so the customer doesn’t repeat everything.
More on this in our guide on when an AI assistant should hand over.
