I tested the best HubSpot AI apps for support teams in 2025

Let’s be real: HubSpot’s AI tools are impressive, but trying to navigate its built-in features alongside the sea of third-party apps in the marketplace can feel like a job in itself. How do you find the tools that actually save your support team time and keep customers happy, without adding a ton of new complexity?

I’ve been down that rabbit hole. That’s why I decided to cut through the noise and spend some serious time testing the top native features and third-party HubSpot AI apps to see what really works. This guide is the result, a straightforward comparison with my honest take on the pros, cons, and pricing to help you make a smart call without sitting through a dozen sales demos.

What are HubSpot AI apps?

When people say HubSpot AI apps, they’re usually talking about two different things that can work together to give your support team a boost.

1. Native AI features: These are the tools built right into HubSpot, like their Customer Agent and Content Assistant. They’re made to work smoothly with your HubSpot data from the get-go.

2. Third-party integrations: These are specialized apps you can grab from the HubSpot Marketplace. They plug into your HubSpot portal to add new AI skills, like automating tricky support workflows or pulling in knowledge from tools outside of HubSpot.

Honestly, the best setup is usually a mix of both. You can use HubSpot’s native tools for the basics and then plug in a more powerful integration to fill in the gaps where you need it most.

How I picked the best HubSpot AI apps

To keep things simple and fair, I looked at each app through the lens of what a busy support team actually cares about:

• Ease of Integration: How quickly can you get it hooked up to HubSpot and actually see it working?

• Core Functionality: Does it solve a real problem (like ticket overload or knowledge gaps) and does it do it well?

• Customization & Control: Can you tweak the AI to match your brand’s voice and fit into your existing workflows?

• Value for Money: Is the pricing easy to understand and does it feel fair for what you get?

The 7 best HubSpot AI apps to boost your productivity

Alright, let’s get into the details of each app, what I liked, what I didn’t, and what it’ll cost you.

1. eesel AI

eesel AI is an AI platform that connects directly to help desks like HubSpot, Zendesk, or Intercom to handle your frontline support. Its standout feature is its ability to learn from all your company’s knowledge, not just what’s tucked away inside HubSpot. It can learn from your past support tickets, but it also connects to your team’s Confluence pages, Google Docs, and over 100 other apps to give customers answers that are actually correct.

Why it’s on the list: Look, HubSpot’s native AI is fine if your entire company lives and breathes HubSpot. But for most teams, knowledge is scattered everywhere. eesel AI closes that gap. You can build a genuinely smart AI agent without the headache of moving all your internal docs into the HubSpot knowledge base. The best part? The setup is completely self-serve, and its simulation mode lets you test the AI on your past tickets so you can go live in minutes feeling confident it won’t go rogue.

Pros:

• Go live in minutes: You can set it all up yourself without ever needing to talk to a salesperson.

• Unifies all your knowledge: It connects to apps outside HubSpot, which means the AI gives much more accurate and helpful answers.

• Risk-free testing: The simulation mode shows you exactly how the AI will handle real tickets before any customer sees it.

• You’re in control: You get to decide precisely which tickets the AI handles and what it’s allowed to do.

Cons:

• It’s a third-party tool, so it is an extra subscription on top of what you’re already paying for HubSpot.

Pricing:

eesel AI’s pricing is refreshingly simple, with no weird per-resolution fees that jump up when you have a busy month.

• Team Plan: $299/month ($239/month if billed annually) for up to 1,000 AI interactions.

• Business Plan: $799/month ($639/month if billed annually) for up to 3,000 AI interactions, plus it can train on past tickets and use AI Actions.

• Custom Plan: For teams with bigger support volumes or more specific needs.

2. HubSpot Customer Agent

This is HubSpot’s own AI agent, part of their "Breeze" AI suite. It’s designed to offer 24/7 support by pulling answers directly from your HubSpot knowledge base and other content you have stored inside the platform.

Why it’s on the list: If your team is 100% HubSpot-or-bust, the Customer Agent is a natural fit. Because it’s tied so tightly into the Smart CRM, it already has customer context, which can help it provide more personalized answers right away.

Pros:

• Seamlessly integrated with the HubSpot CRM and Service Hub.

• Very simple to set up, especially if your knowledge base is already in HubSpot.

• No extra vendors or contracts to manage.

Cons:

• It’s a walled garden. The AI can only learn from knowledge inside HubSpot. If your most important docs are in Confluence, Google Docs, or Notion, it’s not going to be very helpful.

• You have less say over testing and how you roll it out compared to more specialized platforms.

Pricing:

The Customer Agent is part of the Service Hub Professional and Enterprise plans.

• Service Hub Professional: Starts at $90/month per seat (billed annually).

• Service Hub Enterprise: Starts at $150/month per seat (billed annually).

It uses a credit system, where one AI-resolved chat costs 100 HubSpot Credits. Your plan comes with some credits, but this usage-based model can make your bill unpredictable, especially during busy periods.

3. AI Studio for Workflows

AI Studio for Workflows is a HubSpot Marketplace app that lets you stick custom AI actions right into your HubSpot Workflows. You can use it to ping models like OpenAI’s GPT-4 or Google’s Gemini to do things like classify new leads, summarize call notes, or write personalized email snippets on autopilot.

Why it’s on the list: This is a dream for anyone in operations or marketing automation who likes to tinker. It’s less of a customer-facing chatbot and more of an engine for building smart automations behind the scenes, all within the workflow tool you already know.

Pros:

• Super flexible for creating unique, AI-powered automations.

• It fits right into the familiar HubSpot Workflows interface.

• Gives you access to several different top-tier AI models.

Cons:

• This isn’t a ready-to-go support agent; you need to know how to build workflows and write good prompts to get anything useful out of it.

• It’s all about automation, not having real-time conversations with customers.

Pricing:

AI Studio for Workflows has a freemium model.

• Free Plan: Gives you 50,000 tokens per month to play with.

• Paid Plans: Professional, Professional Plus, and Enterprise plans are available if you need more power.

4. ChatSpot

ChatSpot is HubSpot’s AI assistant that helps you manage your CRM just by chatting with it. Instead of clicking through a bunch of menus to build a report or add a contact, you can just type what you want, like "Show me all new leads from last week" or "Add Acme Corp as a new company."

Why it’s on the list: ChatSpot completely changes how you interact with your CRM, making it way faster and easier for everyone on the team. It’s a huge time-saver for sales and marketing folks who feel like they spend half their day on admin tasks.

Pros:

• Makes finding data in your CRM much faster and more intuitive.

• Saves a ton of time on manual data entry and pulling reports.

• Cleverly mixes the power of ChatGPT with your own HubSpot data.

Cons:

• It’s built for your internal team’s productivity, not for handling customer support.

• It’s still in public beta, so you might run into some quirks.

Pricing:

ChatSpot is currently free to use while it’s in public beta.

5. Ada

Ada is a big name in the enterprise chatbot space. It’s a heavy-duty, no-code platform for building complex AI agents for customer service. Ada has a solid integration with HubSpot, which lets the chatbot pull customer context from the CRM and create or update tickets in Service Hub.

Why it’s on the list: For big companies with a ton of support requests, Ada is a go-to choice. Its HubSpot integration is a common setup for enterprises that need a dedicated AI platform that can talk to multiple systems, including their CRM.

Pros:

• Very powerful and can handle complicated, high-volume support.

• The no-code builder is pretty user-friendly for non-technical teams.

• Comes with strong analytics and reporting.

Cons:

• The price tag is definitely aimed at large enterprises and is likely too steep for small or mid-sized businesses.

• The pricing isn’t public. You have to go through their sales process, which can be slow and often means you’re signing a big contract.

• It can feel like you’re managing a totally separate system outside of your main HubSpot world.

Pricing:

Ada uses a custom, quote-based pricing model. You have to talk to their sales team for a demo and a price, which is usually a sign of a high price point and a long-term commitment.

6. Botpress

Botpress is an open-source platform that gives you the tools to build your own custom AI agents and chatbots. It’s made for developers and offers a massive amount of flexibility. Botpress has a ready-made integration for HubSpot, so any bot you build can easily connect to your CRM data.

Why it’s on the list: If you have developers on your team, Botpress gives you a level of control that no-code platforms just can’t offer. You can build a completely unique conversational bot from scratch and hook it directly into HubSpot.

Pros:

• Extremely customizable for teams with the technical chops to use it.

• The core open-source platform is free to use.

• Has a growing library of integrations, including a solid HubSpot connector.

Cons:

• It has a steep learning curve and you’ll need coding skills to build and maintain it.

• It’s the polar opposite of a "go live in minutes" kind of tool.

Pricing:

Botpress offers several tiers.

• Pay-as-you-go: Free to start, then you pay for usage. You get a $5 monthly credit for AI spend.

• Plus: Starts at $79/month (billed annually) + AI spend.

• Team: Starts at $445/month (billed annually) + AI spend.

• Enterprise: Custom pricing.

The "AI Spend" and add-on model can make it tricky to predict what your bill will be each month.

7. HubSpot Content Assistant

HubSpot’s Content Assistant isn’t really a single app, but a bunch of AI tools baked into different parts of the platform. It’s what helps you draft blog posts, come up with social media captions, and write marketing emails with just a few prompts.

Why it’s on the list: It’s probably the most common and easy-to-use AI feature in HubSpot. For any marketer or salesperson, it’s a great way to get past writer’s block and get content out the door faster.

Pros:

• It’s built right into the places you already work (like the email and blog editors).

• Super easy to use, with zero setup needed.

• It’s included for free in all HubSpot plans.

Cons:

• Its only job is to generate content; it doesn’t automate workflows or help with customer support.

• The writing can be a bit generic and almost always needs a human to add some personality and polish.

Pricing:

The Content Assistant tools are included in all HubSpot plans, from the Free tier all the way to Enterprise.

How to choose the right HubSpot AI apps for your team

Feeling a bit lost in the options? Here’s a simple way to figure out what’s right for you.

• First, what are you actually trying to do? Is the main goal to answer customer support tickets automatically? You need a support automation tool. Is it to write blog posts faster? You need a content tool. Pick an app that’s built for the job.

• Where does your team’s knowledge actually live? This is a huge one. If everything is perfectly organized in your HubSpot knowledge base, a native tool might do the trick. But if it’s spread across Confluence, Google Docs, and Slack (like most teams), you absolutely need a tool like eesel AI that can connect to all of it.

• Be honest: do you have developers on hand? Are you a support manager who needs something that just works out of the box, or do you have a tech team ready to build a custom solution with a platform like Botpress? Be realistic about the time and skills you have.

• Always test drive it first. Don’t just flip on a customer-facing AI and cross your fingers. Look for platforms that let you safely test the AI on your past tickets. It’s the only way to know how it will actually perform before you commit.

Unify your tools and go live in minutes

The world of HubSpot AI apps is growing like crazy, but the right tool can really change the game for your team’s productivity. The trick is to find a solution that works the way you already do, instead of forcing you to change your entire process.

While HubSpot’s built-in tools are a good start, they work best when you’re fully committed to their ecosystem. For teams using a mix of different apps, that’s just not how it is.

eesel AI is built for how modern teams actually work. It connects deeply with HubSpot but also with all the other places your team gets things done. With a risk-free simulation mode and a setup so easy you can do it yourself over a cup of coffee, you can start automating support with confidence.
