What Are HubSpot's AI Agents and How Do They Work?

AI is no longer a separate tool inside HubSpot — it’s embedded directly into the platform. If you’ve noticed new AI-powered drafting tools, summaries, or something called “agents,” you’re looking at HubSpot’s Breeze AI system.

But what exactly are HubSpot’s AI agents? How do they work? And how are they different from HubSpot’s AI assistants? Let’s break it down.

What Are HubSpot’s AI Agents?

HubSpot’s AI agents are configurable, task-oriented tools built inside the platform that can perform structured actions using your CRM data.

Unlike simple AI text generators, HubSpot AI agents are connected to your customer records, tickets, deals, and workflows. They operate within defined permissions and guardrails, meaning they can analyze CRM context and take limited actions based on rules you set.

HubSpot offers pre-built agents through its Breeze marketplace, including:

• A Customer Agent designed to handle repeatable customer conversations across marketing, sales, and service channels.
• A Knowledge Base Agent that can analyze resolved tickets and help draft help-center content.
• Data-focused agents that can answer structured questions about CRM records.

These agents are not generic chatbots. They are embedded into HubSpot’s ecosystem and operate within your defined automation framework.

The key distinction is that AI agents can execute tasks — but only inside boundaries you configure.

What Are HubSpot’s AI Assistants?

HubSpot’s AI assistants are different from AI agents.

Assistants help users complete tasks faster by generating suggestions. They do not independently take action inside your CRM.

For example, HubSpot’s AI assistants can draft emails, summarize sales calls, suggest workflow logic, generate marketing copy, or provide explanations of report trends. Tools like Breeze Copilot allow users to ask questions about their CRM data or request content drafts directly inside HubSpot.

Assistants are collaborative. They generate output that a human reviews and approves.

Agents, on the other hand, can automate parts of structured workflows once configured.

Understanding this difference is important for businesses evaluating how to use AI inside HubSpot.

How Do HubSpot AI Agents Work?

HubSpot AI agents operate through Breeze Studio, which is the centralized area where AI behavior is configured and managed.

At a high level, HubSpot AI works by combining large language models with your structured CRM data. When an agent is activated, it can analyze customer records, ticket histories, engagement data, and other stored information. Based on defined rules, it generates responses or performs actions.

However, AI agents do not operate freely across your portal. They function inside:

• Permission settings
• Defined workflows
• Escalation rules
• Approved knowledge sources

For example, a Customer Agent may respond to common inquiries by referencing CRM history and predefined knowledge. If a conversation exceeds its scope, it can escalate to a human team member.

Similarly, a Knowledge Base Agent may review resolved tickets and generate draft help articles for review, rather than publishing them automatically.

The system is structured to support automation without removing human oversight.

Can You Build Custom AI Agents in HubSpot?

Yes. In addition to installing pre-built agents from the Breeze marketplace, HubSpot allows businesses to build custom AI agents inside Breeze Studio.

This means companies can define the purpose of an agent, connect it to specific CRM objects, set response guidelines, and determine how autonomous it should be.

For example, a business could build a custom internal agent that assists sales reps by summarizing deal records in a standardized format before calls. Another team might create an agent that categorizes incoming tickets based on defined criteria.

The ability to build your own AI assistants and agents makes HubSpot’s AI framework flexible rather than fixed. However, customization requires clear processes and structured data to be effective.

What Can HubSpot’s AI Agents Actually Do?

HubSpot AI agents are designed to reduce repetitive, manual tasks across sales, marketing, and service teams.

In marketing, AI assistants can generate first drafts of emails, blog posts, and ad copy. In sales, assistants can summarize calls and draft follow-up messages. In service, agents can handle routine customer inquiries and help generate self-service content from past ticket data.

AI agents can also surface structured insights from CRM data, helping teams understand trends or answer operational questions more quickly.

The common thread is efficiency. HubSpot AI is designed to accelerate work that already exists within a defined system.

It is not designed to replace strategy, define your sales process, or repair inconsistent data.

Will HubSpot AI Change or Damage CRM Data?

HubSpot AI agents operate within defined permissions and workflow rules. They do not independently rewrite or restructure your CRM database.

Actions performed by AI agents are constrained by the configurations set inside Breeze Studio and by user permission levels. Businesses retain control over how autonomous these agents are allowed to be.

That said, AI performs best when data is clean and structured. If your lifecycle stages, deal stages, or properties are inconsistent, AI outputs may be less reliable.

AI does not fix system architecture. It enhances structured systems.

Do Small Businesses Need HubSpot AI Agents?

Small businesses do not need to use every AI feature available in HubSpot.

However, businesses with repeatable processes and limited team capacity may benefit from AI assistants and agents that reduce manual drafting, summarizing, or routing tasks.

For small teams, the value often lies in time savings rather than transformation. When implemented thoughtfully, HubSpot AI can reduce mental load and speed up execution.

The decision to use AI inside HubSpot should be based on process maturity and data cleanliness — not pressure to adopt new technology.

The Bottom Line

HubSpot’s AI agents and assistants are structured tools embedded inside the CRM to help businesses work more efficiently. Assistants generate suggestions and drafts for human review. Agents can execute defined tasks using CRM data and workflow rules.

Both are part of HubSpot’s Breeze AI system, configurable through Breeze Studio and expandable through the Breeze marketplace.

When paired with clean data and intentional workflows, HubSpot AI can reduce friction across sales, marketing, and service operations. Without structure, it adds little value.

AI does not replace strong systems. It supports them.
