HubSpot's AI Customer Agent, powered by Breeze AI, represents a significant leap forward in automated customer support— including turning your website into a responsive, helpful, and continuously improving front-of-house assistant.

This comprehensive guide will walk you through (just about) every aspect of setting up, training, and optimizing your HubSpot AI Customer Agent. In turn, it’ll help you to deliver exceptional customer experiences… while freeing your human agents to focus on complex, high-value interactions.

Now you're warmed up and ready to go, let's look at the step-by-step guide…

Step-by-Step Setup Guide


Pre-planning:

Before you even get started, you'll need to toggle on a couple of switches in the settings area:
In your HubSpot account, click the settings settings icon in the top navigation bar:
In the left sidebar menu, in the Account management section, navigate to AI.
Then you'll need to toggle these two settings (if not already done):

NOW you can get started…

Phase 1: Creating Your Customer Agent

Navigate to the Customer Agent Dashboard

  • In your HubSpot account, go to Service > Customer Agent
  • Click "Launch" to access the Customer Agent interface
  • Select "Create Agent" to begin the setup process

Configure General Information

Agent Name Choose a descriptive name that reflects your agent's purpose (e.g., "Support Assistant," "Product Helper," or your company name + "Bot")

customer_agent_configuration

Role Selection Select the most appropriate role for your agent:

  • Customer Support: Best for general inquiries, troubleshooting, and FAQ responses
  • Marketing Specialist: Ideal for product information, feature explanations, and lead qualification
  • Sales Representative: Optimized for pricing questions, demo requests, and initial sales conversations

Personality Configuration Choose a personality that aligns with your brand voice:

  • Friendly: Warm, approachable, and conversational
  • Professional: Formal, business-focused, and authoritative
  • Casual: Relaxed, informal, and approachable
  • Empathetic: Understanding, supportive, and caring
  • Witty: Clever, engaging, and memorable

Pro Tip: you can configure brand voice settings in HubSpot (under the "Branding" tab within "Account Defaults") for the whole business:

brand_kit

Then you can configure:

Phase 2: Content Configuration

Adding HubSpot Content Sources

customer_agent_content

As your Customer Agent is powered by content, you really want to make sure that what you feed into the system is what you want it to serve up e.g.

Knowledge Base Articles

  • Select your most comprehensive and up-to-date FAQ articles
  • Ensure articles use clear headers and subheaders
  • Include articles that address common customer pain points

Website and Landing Pages

  • Add key product pages that explain features and benefits
  • Include service description pages
  • Add pricing and plan information pages

Blog Content

  • Select evergreen blog posts that answer common questions
  • Include how-to guides and tutorials
  • Add industry insights that position your company as an expert

Product and services information

  • Up-to-date pricing information
  • Technical spec
  • Approach to delivery of services etc

As you can see,  there are many options, and personally, I tend to favor files of 'FAQs' as a starting point.
(Unless you have a well-manicured knowledge base, for instance)

You can add these here…

customer_agent_add_content

Supported File Types You can upload various file formats containing relevant information:

  • PDF documents (product guides, manuals, policies)
  • Word documents (FAQs, internal guides)
  • Text files (scripts, common responses)

And a few tips…

  • Use descriptive file names
  • Ensure content is current and accurate
  • Remove any sensitive or confidential information
  • Structure content with clear headings and bullet points

Very important…

You need to decide whether you want the citations of the answers to be ‘viewable’.
If you toggle
In other words, people won't just see the answers, they'll see the source of the answer as well.

customer_agent_citations

If you toggle, then you make the files ‘available to be cited’ in answers - which is exactly what we've done with our ISO 27001 and ISO 9001 certificates:

ISO 27001 and ISO 9001 certificates

Note: you may not want this to be the case across all of your content.

Once you have your content ready, you can move to the next phase…

Phase 3: Channel Assignment

customer_agent_assign

Select Your Deployment Channel:

customer_agent_assignment

Inbox vs. Help Desk Configuration Choose whether to connect through:

  • Conversations Inbox: Best for general customer communications
  • Help Desk Workspace: Ideal for structured support ticket management

Channel Selection Assign your agent to appropriate channels:

  • Live Chat: Website visitors get immediate assistance
  • Facebook Messenger: Social media customer support
  • WhatsApp Business: Mobile-first customer communication
  • Email (BETA): Automated email response handling

Configure Handoff Rules:

customer_agent_config

Handoff to Human Agent Configure when and how conversations transfer to human agents:

  • Select specific users or teams for escalation
  • Set up routing rules based on inquiry complexity

Stay Assigned Option Choose this if you want the AI to remain engaged even when it can't answer:

  • Customize the "handoff unavailable" message
  • Maintain conversation continuity
  • Allow for follow-up questions and clarification

Testing and Optimization

Next, it's time for some ‘Pre-Launch Testing’
Before going live, test your agent with:

  • Common customer questions from your support history
  • Edge cases and unusual inquiries
  • Questions that might reveal knowledge gaps
  • Multi-part or complex questions

preview and test customer agent

See how it responds, and you may need to adjust the source of the information, and/or use short answers to fill in any gaps:

customer_agent_add_content_2

Advanced Configuration Strategies

You can also set up something called Actions, which is definitely a more advanced approach where you can…

“Empower Customer Agent to perform tasks just like your support reps. Configure actions like sending invoices, sharing order status, or sending password reset links — all without the hassle of manual intervention.”

describe_the_action

More information on that here. 

Once you GO LIVE…

customer_agent_performance

When your agent frequently expresses uncertainty, the issue is usually poor content quality or gaps in your knowledge base. 

If you run the test yourself and then review the responses, you'll often find the source of the issues. 

This is why ‘Short Answers’ (mentioned above) are SO useful…
Spot a ‘Knowledge gap’ once live (By going to this tab below)

customer_agent_knowledge_gaps

Click on the hyperlink relating to the gaps, and then use short answers to build out the information to be used by the Customer Agent, by clicking on the ‘Create an answer’ button:

customer_agent_create_an_answerpng

And then add in both the question and the answer. 

customer_agent_create_short_answer

You can even test it before you go live:

customer_agent_preview

This gives a way for your customer agent to build a micro knowledge base through ‘short answers’. 
It's early days with our own experimentation, but I'm extremely excited with the potential.
