So, you're all-in on HubSpot. It's a fantastic platform for your CRM and marketing, but let's be honest, their AI chatbot options are a bit of a letdown. You’ve probably noticed that their "Breeze Customer Agent" is tucked away in the more expensive plans and charges you roughly a dollar for every conversation. On the other end, the free Chatbot Builder is just too basic for a real AI-powered chat. It feels like you’re stuck choosing between paying too much or getting too little.
That's exactly why I decided to test a bunch of different tools to find the actual best HubSpot AI chatbot out there. This guide breaks down my top 5 picks that connect right into your HubSpot CRM. They can help you automate support, qualify leads, and handle more conversations without emptying your wallet.
What is the best HubSpot AI chatbot?
Before we jump into the list, let's get on the same page. A HubSpot AI chatbot isn't just a feature inside HubSpot. It’s any AI chat tool that's built to work smoothly with your HubSpot CRM.
This is different from a basic, rule-based bot that just follows a script (like HubSpot's free builder). A proper AI chatbot uses natural language processing (NLP) to actually understand what people are asking and respond in a way that doesn't sound robotic. For anyone using HubSpot, the dream is to have a bot that can:
-
Chat with website visitors 24/7, whether they need help or are interested in a sale.
-
Ask smart questions to figure out if a visitor is a good lead.
-
Book meetings or schedule demos right in the chat.
-
Create and update contacts automatically in your HubSpot CRM.
The integration part is what matters most. The best tools don't just sit on your website. They feed useful information and good leads directly into HubSpot, making your sales and marketing teams' lives a whole lot easier.
How we picked the best HubSpot AI chatbot
I didn't just pull these names out of a hat. My testing was focused on what really matters to businesses that rely on HubSpot to grow. Here's the checklist I used to rank these tools:
-
How easy is it to connect to HubSpot? I looked for tools you can get up and running quickly on your own, without needing a developer or sitting through long sales calls.
-
How smart is the AI? Can the bot do more than spit out FAQ answers? I wanted chatbots that you could train on your own business info, customize workflows for, and even have them perform tasks like looking up an order status.
-
Does it actually help with leads and support? The whole point is to capture more leads and solve customer problems. I checked how well each bot could qualify prospects, book meetings, and give helpful answers.
-
Is the pricing straightforward? No one likes surprise bills. I gave extra points to platforms with flat-rate plans instead of confusing per-conversation models that charge you more as you get more successful.

The 5 best HubSpot AI chatbot alternatives in 2025
Alright, let's get into the details of each platform.
1. eesel AI
eesel AI quickly became my top choice because it’s made for teams that want a seriously powerful AI without all the usual enterprise-level headaches. You can build an AI agent that learns from your entire knowledge base (not just a single help center) and gives you complete control over how it behaves, all from a platform you can launch yourself in minutes.
HubSpot's AI can feel like a "black box" that costs a lot of money. eesel AI is the opposite. It’s transparent and flexible. You get to decide exactly what kinds of questions the bot should handle, adjust its personality, and use its workflow engine to set up custom actions, like creating a new deal or updating a contact's info in HubSpot. Getting that level of control in other tools usually involves a long, expensive custom project.

You can see exactly how it would have replied, get a forecast of your automation rate, and tweak its performance before it ever talks to a real customer. Add in the predictable, flat-rate pricing (no per-conversation fees here), and it's the smartest option for any business looking to grow.

-
Super simple setup: You can sign up and have a trained AI ready to go in minutes, no sales call needed.
-
Total workflow control: The prompt editor and custom API actions let you make the bot a genuine part of your team.
-
Connects all your knowledge: It can learn from past tickets, Confluence, Google Docs, Notion, and other sources.
-
Risk-free simulation: Test on your own historical data so you can launch with confidence.
-
Predictable pricing: Your bill won't suddenly jump just because you had a busy month.

-
Some of the more advanced features are on the higher-tier plans.
-
If you just need a very simple lead capture form, this might be more firepower than you need.
Pricing:
| Plan | Monthly Price (Billed Annually) | Monthly Price (Billed Monthly) | Key Features |
|---|---|---|---|
| Team | $239 | $299 | Up to 3 bots, 1,000 interactions/mo, train on docs, AI Copilot, Slack integration. |
| Business | $639 | $799 | Unlimited bots, 3,000 interactions/mo, train on past tickets, MS Teams, AI Actions, bulk simulation. |
| Custom | Contact Sales | Contact Sales | Unlimited interactions, advanced actions, custom integrations, multi-agent orchestration. |
2. Resolve247
Resolve247 is a really interesting option because it does one thing very well: it gives you a cost-effective AI chatbot that works right inside the HubSpot chat widget. Its main draw is the price. For a low monthly fee, you get a ton of conversations, which makes it a great replacement for HubSpot's pricey pay-per-chat model.
It's designed to be a drop-in replacement for HubSpot's Breeze Customer Agent, so you can add a smarter AI to your existing chat without having to upgrade your HubSpot subscription. That means it’s available even if you're on HubSpot’s Free or Starter plans. You can also give the AI custom instructions to tweak how it behaves, giving you more flexibility than HubSpot’s own tool.
While it’s great for the price, it’s mostly focused on answering questions from your knowledge base to reduce support tickets. It doesn't have the advanced workflow automation or ability to learn from multiple knowledge sources that a tool like eesel AI offers. Still, for small businesses that just want to answer common questions and lower support costs, Resolve247 is a solid pick.
Pros:
-
Very affordable, with plans starting at just $29/month.
-
Works with any HubSpot plan, including the free one.
-
Simple setup that uses your existing HubSpot chat widget.
-
Lets you write custom instructions to guide the AI.
Cons:
-
Not built for complex, multi-step automations.
-
Its AI capabilities are mostly limited to what's in your knowledge base.
-
Their official website seems to be down as of late 2025, which makes me wonder about its future.
Pricing:
Note: This pricing is based on info from the company's blog since their main website isn't working right now.
-
Starter: $35/month ($29/mo annually) for 2,000 AI responses.
-
Core: $55/month for 4,000 AI responses.
-
Scale: $125/month for 10,000 AI responses.
3. Intercom
You’ve probably heard of Intercom. They're a big name in customer communication, and their AI chatbot, Fin, is a core part of their platform. This is a good choice for teams who want their chatbot, live chat, help desk, and marketing messages all under one roof.
Their AI is trained on billions of support chats, so it's pretty good at giving high-quality, relevant answers. The HubSpot integration is solid, letting you sync contacts, companies, and chat history without any trouble. This makes it easy to see the entire customer journey, from their first question in the chat to becoming a closed deal in HubSpot.
The catch is that Intercom isn't just a chatbot, it's a whole new platform. You're not just adding a bot; you're moving your whole support and sales chat operation over to their system. That can be powerful, but it's a big commitment. The pricing is also a bit complicated. It’s a mix of per-seat and per-use fees (including a charge for every problem the AI solves), which can get expensive and hard to predict.
Pros:
-
A polished, all-in-one system for sales and support.
-
High-quality AI that’s good at conversation.
-
A smooth and reliable sync with the HubSpot CRM.
Cons:
-
You have to commit to their entire platform (vendor lock-in).
-
The pricing is complex and can get expensive unexpectedly.
Pricing:
| Plan | Annual Price (Per Seat/Month) | Key Features |
|---|---|---|
| Essential | $29 | Includes Fin AI Agent, Messenger, and a shared inbox. |
| Advanced | $85 | Adds multiple inboxes, workflow automation, and 20 Lite seats. |
| Expert | $132 | Adds SSO, HIPAA support, SLAs, and 50 Lite seats. |
Just remember, all plans also have a $0.99 fee for every problem Fin resolves on top of the seat price.
4. Wonderchat
Wonderchat is a no-code AI chatbot builder that's great for businesses needing a simple way to grab leads and answer basic questions. Its biggest strength is its simplicity. You can train a chatbot on your website content or PDFs in a few minutes and have it live on your site right away.
The HubSpot integration is easy to connect and does what you need it to do: any leads the bot collects are automatically sent to your HubSpot contacts. This means no more manual data entry and your leads get into your marketing funnels faster.
Wonderchat is definitely best for straightforward tasks. It doesn't have the deep customization, workflow automation, or detailed analytics you'd find in more advanced platforms. If your main goal is to make your static contact form a little more interactive, Wonderchat is a great place to start. But if you need an AI that can handle more complicated processes, you might find it limiting pretty quickly.
Pros:
-
Very easy to use with its no-code interface.
-
Fast setup and a simple integration with HubSpot.
-
Affordable pricing for the basic features.
Cons:
-
Not many options for customization and automation.
-
Missing advanced features like simulation mode or detailed analytics.
Pricing:
Note: Wonderchat's pricing page wasn't working, so this info comes from their blog content.
-
Hobby: $40/month for 2,000 message credits.
-
Standard: $150/month for 12,000 message credits.
-
Pro: $500/month for 40,000 message credits.
5. Botpress
Botpress is a powerful platform for developers who need to build complex, custom AI chatbots. If you have a dev team and need to create a chatbot with very specific logic, Botpress gives you a ton of flexibility. It has a visual builder, but its real strength is its open architecture that lets you expand what it can do with your own code.
The HubSpot integration works through their API-first design. This means you have to set up the API calls yourself (or use a tool like Zapier), but it also means you can make it do pretty much anything you want, from creating contacts and updating deals to logging detailed notes and triggering HubSpot workflows.
Botpress is not for beginners. You need some technical skill to set it up and keep it running, and it's far from a "plug-and-play" tool. But for teams that want full control and have the ability to build their own solution, Botpress is an incredibly powerful foundation.
Pros:
-
Extremely flexible and can be customized endlessly.
-
Offers both a powerful visual editor and deep developer tools.
-
Has a generous free plan to get you started.
Cons:
-
You'll need technical knowledge to set up and manage the HubSpot integration.
-
Has a much steeper learning curve than the no-code tools on this list.
Pricing:
| Plan | Annual Price (Per Month) | Key Features |
|---|---|---|
| Pay-as-you-go | $0 + AI Spend | Visual studio, $5 monthly AI credit, community support. |
| Plus | $79 + AI Spend | Adds human handoff, conversation insights, watermark removal. |
| Team | $445 + AI Spend | Adds role-based access, real-time collaboration, custom analytics. |
| Enterprise | Starts at $2000/mo (3-year term) | Adds whiteglove onboarding and a dedicated support manager. |
Botpress plans also have various add-ons for things like messages and bots, which can add to the monthly cost.

3 key things to consider when choosing the best HubSpot AI chatbot
Feeling a bit lost in the options? Here are three final tips to help you make the right call:
-
Look for self-serve and simulation. Your team is busy, and you don't have time for endless sales demos or a months-long setup process. Find a tool you can get running yourself in a few minutes. Even better, pick one with a solid simulation feature, like eesel AI, so you can actually test it and prove it works before a single customer interacts with it.
-
Watch out for per-conversation pricing. It might look cheap at first, but pricing that charges you for every conversation or resolution punishes you for being successful. As your website traffic grows, so will your bill. A predictable, flat-rate subscription is almost always a better deal in the long run.
-
Think beyond just answering questions. The best AI chatbots don't just give out information; they get things done. Look for a tool that lets you build custom workflows. The ability to connect to your other systems (including HubSpot) is what turns a simple FAQ bot into an AI agent that can actually solve problems and bring in revenue.

While HubSpot is an amazing all-in-one platform, its own AI chatbot offerings just don't cut it for a lot of businesses because of the high cost and limited features. The good news is, there are plenty of powerful, flexible, and more affordable options out there.
For teams that want a great balance of power, control, and ease of use, eesel AI is my top recommendation. Its self-serve platform, powerful simulation mode, and predictable pricing make it the smartest choice for businesses that are serious about using AI to grow.
At the end of the day, the best chatbot is the one that fits into your HubSpot workflow, helps you reach your goals, and gives your customers a great experience.

Frequently asked questions
HubSpot's native AI chatbot options are often limited in features and can become quite expensive with per-conversation pricing. Third-party alternatives typically offer more advanced customization, powerful integrations, and predictable flat-rate pricing, making them a more robust and cost-effective choice for sophisticated automation.
Most of the highly-rated tools are designed for seamless integration with HubSpot. Many offer direct, no-code connections that allow you to sync contacts, company data, and chat transcripts automatically, ensuring your sales and marketing teams have up-to-date information.
Absolutely. The top-tier chatbots go far beyond simple FAQ answering. They can be trained to perform complex lead qualification, book meetings directly into your calendar, and even update contact properties within HubSpot, leveraging natural language processing to understand nuanced queries.
It's generally recommended to look for predictable, flat-rate subscription models over per-conversation or per-resolution pricing. While per-use models might seem cheaper initially, they can lead to unexpectedly high costs as your chatbot handles more interactions and becomes more successful.
Look for platforms that offer a simulation mode, like eesel AI. This feature allows you to test your chatbot's responses and predicted automation rate against your own historical customer conversations, giving you confidence in its performance before deploying it to real users.
A basic rule-based bot follows predefined scripts and keywords, offering limited flexibility. In contrast, the best HubSpot AI chatbot solutions utilize advanced natural language processing (NLP) to understand context, intent, and complex queries, enabling more dynamic, human-like conversations and sophisticated task automation.
