An AI-powered live chat tool handles recurring questions automatically and routes all other conversations to your team. HubSpot, Zendesk, Intercom, LiveChat, Tidio, and Userlike each offer an AI agent within chat for this purpose. The tools differ across six key areas: answer sources, human handoff, channels, shop and CRM integration, data location, and pricing. Which tool suits you best depends primarily on the systems your team already uses today.

All information regarding the providers is sourced from their own websites and applies as of November 11, 2026. The sources are listed at the end of this article.

Six criteria to help you find the right tool for your customer service

1. Answers from your own sources. The AI should only answer using content you have approved. This includes help articles, product data, and documents. Ask which sources a tool can ingest and how frequently it updates them.

2. Human handoff with context. When the AI reaches its limits, your team takes over. Your team then needs the complete conversation history and the information the customer has already provided. Otherwise, they will have to ask for everything all over again.

3. Channels. Your customers reach out via your website, WhatsApp, Instagram, or email. Check whether the AI responds across all channels with the same knowledge base.

4. Shop and CRM integration. The AI needs data from your shop or ERP to answer questions about orders, delivery times, and pricing. For lead generation, it should also create inquiries directly in the CRM.

5. Hosting and data privacy. Clarify in which region the conversations are hosted. Also ask whether the provider uses your data to train their models.

6. Pricing. Many tools bill per user seat. In addition, there is often a fee per conversation or per resolved inquiry for the AI. This means your costs rise with conversation volume, such as during the peak holiday season. Read more about this in our article on why your chatbot platform should not bill per agent.

The guide Selecting AI-Powered Live Chat Software shows how to test these criteria using your own inquiries.

Two tables showing you the differences at a glance

The first table shows where the AI pulls answers from, how it handles handoffs, and which channels it supports.

The second table highlights shop and CRM integration, data location, and pricing models.

Pricing, plans, and features change frequently. Therefore, verify the details directly with the provider before making a decision. Several providers specify exceptions regarding data location on their help pages, such as for billing or usage data. Be sure to address this during contract negotiations.

Userlike now operates under the name Lime Connect.

How to find the tool that matches your current setup

Identify which of these six typical scenarios applies to your business.

Your sales team already works with HubSpot. HubSpot offers live chat, an AI agent, and CRM from a single source. The Customer Agent hands over conversations to HubSpot's inbox or help desk. The Shopify integration syncs customers, products, and orders into the CRM.

Your support team works with tickets in Zendesk. Zendesk includes AI agents in all Suite and Support plans. You can also choose AI from another provider. Fin by Intercom and Mercury.ai both hand over conversations to Zendesk.

You run a Shopify store with a small team. Tidio offers a free plan, and Tidio’s AI utilizes order data from Shopify directly within the conversation. According to its website, LiveChat is also tailored for one-person teams. LiveChat's AI checks order statuses via Shopify.

Your team handles a high chat volume themselves and requires hosting in Germany. Userlike states that it develops and hosts its software in Germany. You can add an AI agent as an additional module.

You want to place an AI layer in front of your existing help desk. Intercom offers Fin without requiring you to switch your help desk. According to Intercom, Fin integrates with platforms like Zendesk, Salesforce, or HubSpot.

Your customers ask about product specifications, stock levels, and orders. In this case, the AI requires access to your shop, PIM, and ERP systems. In addition, the data often needs to remain in Germany. Mercury.ai is built specifically for this use case.

Keep your existing live chat tool with Mercury.ai

Mercury.ai is a conversational AI platform. The chatbot answers questions exclusively from the sources you approve. These include product data from shop, PIM, and ERP systems, as well as spec sheets, manuals, and your website. Mercury Intelligence validates every response against these sources before outputting it. This significantly reduces the risk of AI hallucinations.

The chatbot routes all other conversations to your team. The destination can be Zendesk, Userlike, or Mercury.ai’s Agent Desk. Your team sees the full history along with all details the chatbot has already captured. In Agent Desk, the conversation returns to the chatbot after the live chat concludes. This allows your team to continue using their familiar live chat tool.

Mercury.ai offers standard connectors for Shopware, Shopify, and Magento. Mercury.ai also integrates with CRM systems like Salesforce, HubSpot, and Pipedrive. This allows the chatbot to log qualified leads directly into your CRM. The e-commerce page details the use cases this covers in online retail.

Mercury.ai processes all data via AWS Frankfurt and therefore exclusively in Germany. No data is transferred to third countries. Mercury.ai hosts its language models independently and does not use your data to train models. Mercury.ai charges a flat monthly rate with no fees per conversation or per agent. An unlimited number of team members can work in Agent Desk.

A lightweight chat widget keeps your website fast

A chat widget loads code across every page of your shop. If the script blocks page rendering, your website slows down. Google measures user experience using Core Web Vitals, including INP for responsiveness and CLS for visual stability. Your IT team should focus on three aspects during implementation:

1. Embed the script using the defer or async attribute. This ensures page rendering is not blocked by the script.

2. Ensure that the chat button does not cause content layout shifts when it appears.

3. Check mobile devices to ensure the chat window does not obstruct the buy button.

The Mercury.ai Chat Widget operates without an iFrame and adapts seamlessly to mobile screens. It aligns with WCAG guidelines and announces new responses for screen readers. The widget sets at most one cookie with an anonymous ID. In its cookie-free mode, the widget does not require a cookie banner. For details, visit the Chat Widget page and refer to the website integration guide.

The six criteria also apply to custom-built widgets

Some teams build their own chat window using code generators. OpenAI also offers ChatKit, providing a chat interface that developers can embed into custom apps and websites. While this sets up the UI quickly, your team must still address the six criteria mentioned above on their own. They must connect data sources, build human handoff workflows, and handle hosting, followed by ongoing maintenance. The article Build vs. Buy: Chatbots highlights when custom development is worthwhile.

Five questions to clarify data privacy before signing a contract

1. Where are conversations stored, and what data leaves the region regardless?

2. Does the provider execute a Data Processing Agreement (DPA) in accordance with Art. 28 GDPR?

3. Does the provider use your data to train their models?

4. Can your customers identify that they are communicating with an AI? Article 50 of the EU AI Act mandates this disclosure.

5. Who determines conversation retention and deletion periods?

Mercury.ai provides a Data Processing Agreement compliant with Art. 28 GDPR. AI disclosure according to the EU AI Act is enabled by default in the Chat Widget. Data retention periods for conversations can be configured on a per-project basis. The Security Paper on the EU AI Act details these measures in full.
