Does your company use HubSpot, and are you looking for the best AI tool for your customer service team? 🤔 The short answer: it all depends on where your agents handle tickets.
If your support team uses HubSpot Service Hub, the native AI (Customer Agent) and several third-party tools can work directly within your tickets: Klark, eesel AI, Fin by Intercom, or Yuma. If HubSpot is only your CRM and support is handled through another help desk, you’ll need to integrate the AI with that help desk.
In this comparison, we explain both scenarios. We then review six HubSpot-compatible solutions for 2026, covering how they work, integration options, list prices, strengths, and limitations.
Let's go! 🚀
HubSpot is primarily known as a CRM. The company reports having more than 306,000 customers as of the end of June 2026. Many use it for marketing and sales. Some also use it for customer support, via Service Hub.
Before choosing an AI, identify your specific situation.
Your agents handle tickets in Service Hub (inbox, help desk, ticket pipelines). Therefore, the AI must read and respond within HubSpot.
Your options:
The Customer Agent native AI, or a third-party tool connected to Service Hub (Klark, eesel AI, Fin, Yuma).
Your agents work in Zendesk, Gorgias, Freshdesk, Intercom, or another tool. HubSpot is primarily used for marketing and sales.
Your options:
Integrate the AI with your help desk, where responses are drafted. And check how conversations are synced with HubSpot (contacts, notes, history).
Good to know: Customer Agent only works within HubSpot. If your tickets are hosted elsewhere, a third-party AI solution will often be simpler.
Service Hub is HubSpot's customer service module. It is billed per seat (per agent), with a setup fee for higher-tier plans.

In plain English?
Service Hub does a great job of organizing support and linking it to the CRM history. But without AI, your agents are still the ones writing each response. And a large portion of the requests are repetitive: order tracking, returns, and questions about a subscription or an invoice.
AI can:
As with any help desk, there are two distinct approaches.
The AI responds directly to the customer and transfers the call to a human when it doesn't know how to handle the situation.
Ideal for:
High-volume, repetitive requests.
The AI prepares a response, which the agent reviews, adjusts, and then sends.
Ideal for:
Sensitive requests, high-value customers, premium brands.
The best solutions combine both approaches. You automate what can be automated, and you free up your agents to focus on the rest.
A few points of reference:
The message is clear: processing all tickets manually is becoming increasingly expensive compared to teams that rely on AI.
Here are the main compatible solutions, ranging from native options to specialized tools.
What it is:
HubSpot's AI agent, part of the Breeze suite. It responds to customers, resolves tickets, performs actions in the CRM, and forwards cases to your teams along with the context. It learns from your content (knowledge base, pages, documents).
Highlights :

What it is:
A French generative AI platform based in Bordeaux, designed for retail and e-commerce brands. Klark integrates with HubSpot as well as most helpdesks on the market. It’s therefore a viable option in both cases: support within HubSpot or on another helpdesk.

What it is:
Intercom's AI agent, which you can use without leaving your helpdesk. Fin connects to HubSpot via OAuth: it syncs your articles and customer data, handles email and chat tickets (via Fin Messenger), and then forwards them to your agents in HubSpot along with the full conversation.

That's the first question to ask. If your agents work in Service Hub, choose an AI that reads and responds within HubSpot. Otherwise, connect the AI to your help desk and make sure conversations are synced to the CRM.
Customer Agent requires the Professional or Enterprise plan, which includes onboarding fees and a minimum commitment per seat. On the Free or Starter plans, a third-party AI is often the only realistic option.
If your brand prioritizes strong customer relationships, start with a co-pilot. You can then expand automation to areas you’ve mastered.
Credits, results, tickets, successes: compare them on an equal basis. Check what triggers billing and what happens when a human takes over.
Test it on your actual tickets. Compare the tone, accuracy, and handling of edge cases. Track your CSAT before and after.
If you sell in France or Europe, test the quality in French and your other languages. See our guide on multilingual customer service.
List where your requests come in: email, chat, forms, social media, phone. And where they are processed: HubSpot or another tool.
Identify the 10 most common reasons for customer contact. In e-commerce, order tracking almost always tops the list.
An AI cannot create your return policy. Update the HubSpot Knowledge Base, your response templates, and your terms and conditions.
Run the AI in draft or co-pilot mode for a few weeks. Your agents will review and correct the output, and you'll be able to measure its actual quality.
Implement automation for issues you've mastered, then track the automation rate, CSAT, FCR, and cost per ticket.
"The AI is going to give my clients all kinds of nonsense answers."
Not if you start off on the right foot. Co-pilot mode lets you review each response before sending it. And the more serious support teams escalate to a human as soon as they have any doubts.
"I have to upgrade to Professional to get AI."
For Customer Agent, yes. But several third-party tools work with Service Hub Starter or on another help desk if HubSpot is just your CRM.
"I don't understand HubSpot credits at all."
You're not alone. Try this calculation: number of conversations × 50 credits, minus the credits included in your plan. Then compare that to an AI service billed per ticket or per successful resolution.
"Switching tools means months of work on the project."
Not with an AI that integrates with your current help desk. You keep HubSpot, your pipelines, and your routines.
Does HubSpot have AI for customer service?
Yes. Customer Agent, part of the Breeze suite, responds to customers and resolves tickets in HubSpot. It requires a Professional or Enterprise plan.
How much will Customer Agent cost in 2026?
HubSpot charges 50 credits per resolved conversation on text-based channels, which is approximately $0.50. Service Hub Professional includes 3,000 credits per month, and Enterprise includes 5,000.
Can we use third-party AI with HubSpot Service Hub?
Yes. Klark, eesel AI, Fin d'Intercom, and Yuma integrate with HubSpot so you can handle tickets without leaving the tool.
I use HubSpot as my CRM but Zendesk for support: Which AI should I choose?
Connect the AI to Zendesk, where your agents respond to inquiries. Klark, for example, integrates with Zendesk, Freshdesk, Gorgias, and other helpdesks. Then see how the conversations are synced to HubSpot.
Which AI tool should I choose on Service Hub Starter?
Customer Agent isn't available there. Try a third-party AI that's compatible with Starter, and test it on your actual tickets.
Klark was designed for customer service teams in retail and e-commerce. Here's what sets it apart:
Support in HubSpot or on another help desk: AI integrates right where your agents work.
The AI learns from your ticket history. No need to design a workflow or maintain a scenario.
Start by supporting your agents, then automate when you're ready.
You pay only for the tickets that are actually processed, with no credits to keep track of. A ticket is never billed twice.
A 50% increase in productivity and an average of 43% of tickets automated among our clients.
