HubSpot Chatbot Review (2026): Free Bots, the AI Agent and What It Costs

The HubSpot chatbot is the chat built into HubSpot's CRM, and it comes in two forms. The rule-based chatbot follows flows you build from templates and is part of HubSpot's free tools. The customer agent, part of HubSpot's Breeze AI, writes its own answers from your website and help content, and needs a Professional or Enterprise plan plus HubSpot Credits.SourcesHubSpot ↗

Who should use which? If your contacts, deals and meetings already live in HubSpot, turn on the free chat and a rule-based bot first: it costs nothing and every answer lands in the CRM. Add the customer agent when visitors ask more questions than your team can answer and you already pay for a Professional hub. If the job is booking sales meetings from your website chat, Darwin is the best fit, because it shows meeting times inside the chat and tests its own opening lines on real visitors. If you are not on HubSpot at all, the alternatives section compares five tools by who they suit.

Who wrote this, and how: we make Darwin, so we are not neutral. It competes with HubSpot's chatbot for one job, booking sales meetings, which is why it gets its own section after the parts about HubSpot and appears third of five among the alternatives. We read HubSpot's pricing, product and help pages in September 2026 and again on 5 October 2026, and asked HubSpot's own website chat about price and booking on 2 October. We did not set up a HubSpot account for this review. Every price below is a dated fact; hover over it for the source.

The rule-based chatbot is a chatflow: a welcome message, then a series of questions and actions you arrange. HubSpot offers templates for qualifying leads, sharing a meetings link and creating support tickets, and on Professional and Enterprise plans a concierge bot, a knowledge base bot and an offline bot. Each answer can be saved to a contact property, so the visitor's company size or use case is already in the CRM when your team picks up the conversation.SourcesHubSpot ↗

HubSpot's rule-based chatbots need a Professional or Enterprise subscription for if/then branches; free and Starter users cannot add them. Without branches, every visitor walks the same path whatever they answer.SourcesHubSpot ↗

The customer agent is the HubSpot AI chatbot, part of Breeze. You give it knowledge sources and guidelines, and it writes its own replies, hands hard conversations to a person, and can qualify leads against criteria you set. HubSpot positions it mainly as a support agent, and it works on live chat, email, forms, WhatsApp and Facebook as well as your website.SourcesHubSpot +1 ↗

HubSpot's free tools include live chat and a limited chatbot with HubSpot branding. In practice that is the chat widget, the shared inbox and a rule-based bot. Starter plans remove the branding, and Sales Hub Starter lists $20/seat/mo.SourcesHubSpot ↗

The HubSpot free chatbot uses the same builder and the same templates as the paid plans, so the free chatbot HubSpot includes is a fair test of whether rule-based chat suits your visitors. What you give up is if/then branching and the Professional-only templates, and the widget keeps HubSpot's branding. HubSpot's free tools cover up to 2 users at no cost.SourcesHubSpot +1 ↗

HubSpot's customer agent needs a Professional or Enterprise subscription to a HubSpot hub and runs on HubSpot Credits. So the AI part is not free: you pay for Professional seats, and the agent draws on credits each time it resolves a conversation.SourcesHubSpot +1 ↗

HubSpot gives 14 days of unlimited Customer Agent use when you buy at least one Service Hub Professional or Enterprise seat. That is the cheapest way to see what the AI agent resolves on your own traffic before credits start to count.SourcesHubSpot ↗

HubSpot chatbot setup starts the same way for both versions, because both run in HubSpot's chat widget: the first two steps are shared. If your site is not hosted on HubSpot, the bot will not appear until HubSpot's tracking code is on your pages, pasted before the closing body tag. Our guide to adding a chatbot to any website shows where that goes on WordPress, Webflow, Shopify and other platforms.SourcesHubSpot ↗

A rule-based bot in the HubSpot chatbot builder

1. Install the HubSpot tracking code on every page of your site.
2. Connect a chat channel to the conversations inbox or help desk, and set the widget's color, name, avatar and team availability.
3. Go to Service, then Chatflows, click Create chatflow and choose Website.
4. Pick the inbox and language, choose Rule-Based Chatbot, then a template such as Qualify leads or Meetings bot, or start from scratch.
5. Edit the welcome message, then add actions: questions, property updates, knowledge base articles or Book a meeting.SourcesHubSpot ↗
6. Click Preview and chat with it. Actions in the preview are real, so a test booking creates a real meeting.
7. On the Target tab, choose the pages it appears on, save, and toggle the chatbot on.SourcesHubSpot ↗

Triggers, targeting and language

Three tabs in the HubSpot chatbot builder decide who sees the bot and when. On the Target tab you show it by page URL, by query parameter or by what the CRM already knows about the visitor, and exclude pages such as your privacy policy. On the Display tab you choose whether the welcome message pops up on exit intent, after some time on the page or after the visitor scrolls part of it. On the Options tab you set the typing delay, the session timeout, the consent banners and the bot's language.SourcesHubSpot ↗

The language is set per chatflow, so a site in several languages needs a chatflow for each one, targeted to the matching pages. One more trick from HubSpot's guide: adding #hs-chat-open to the end of a page URL opens the chat as the page loads, which is handy in emails and ads that promise a conversation.SourcesHubSpot ↗

The customer agent

1. Go to Service, then Customer Agent.
2. Under Train, then Knowledge, add content: HubSpot pages and articles, public URLs (HubSpot can crawl related pages on your domain), files or short written answers.SourcesHubSpot ↗
3. Set guidelines and topics to avoid, and pick a tone: a preset, or a brand voice HubSpot builds from your writing samples.SourcesHubSpot ↗
4. Under Train, then Actions, set lead qualification criteria and route qualified leads to Book a meeting with a meetings link.SourcesHubSpot ↗
5. Preview and test its answers, and set when it hands a conversation to a person.
6. Under Deploy, then Channels, assign it to your website's live chat. HubSpot suggests starting with one channel or a share of conversations.SourcesHubSpot ↗

Every rule-based bot starts from a template or a blank flow, and the six templates are the most useful HubSpot chatbot examples, because each one is a job HubSpot expects its chat to do. Three work on any plan; three need a Professional or Enterprise subscription.SourcesHubSpot ↗

• Qualify leads bot. Asks who the visitor is and why they came, and saves each answer to the contact record.
• Meetings bot. Shares a meetings link so the visitor can book time with you or your team.
• Tickets bot. Gathers the details of a support question and creates a ticket in the inbox.
• Concierge bot (Service Hub Professional or Enterprise). Asks why the visitor is chatting, then sends them to knowledge base search, a person or a meeting.
• Knowledge base and support bot (Service Hub Professional or Enterprise). Shares help articles first, then offers a person or a ticket.
• Offline bot (Sales Hub or Service Hub Professional or Enterprise). Routes visitors to available team members during business hours and collects an email when the team is away.

An example flow for a pricing page

Here is how a B2B team on Sales Hub Professional might combine those pieces on its pricing page. This is our example, not one of HubSpot's, and every step uses an action from HubSpot's guides:SourcesHubSpot ↗

1. Welcome message: "Comparing plans? I can help you pick one or set up a call."
2. A question with quick replies for team size, saved to a contact property.
3. An if/then branch: larger teams go on to booking, smaller teams get a help article on choosing a plan.
4. Ask for name and email, so the meetings link can keep the booking inside the chat.
5. Book a meeting, with a round-robin meetings link for the sales team.
6. On the Display tab, show the welcome message once the visitor has scrolled half the page.

Step 4 matters more than it looks. Without it, HubSpot sends the visitor to a separate booking page, which is one more page to abandon. The next section explains the conditions.

• Everything lands in the CRM. Answers become contact properties, conversations sit on the contact record, and meetings go on the rep's HubSpot calendar. No sync to build or break.
• The basic version is free. A small team can run live chat and a qualifying bot without paying anything.
• The AI agent reads what you already have. The customer agent can import public website URLs and HubSpot pages as knowledge.SourcesHubSpot ↗
• Reporting covers support well. HubSpot reports how many conversations the agent resolved, deflected or escalated, and which sources it used.SourcesHubSpot ↗

We asked HubBot, the chat on hubspot.com, what HubSpot costs and whether it can book a meeting. It asked for a work email instead of quoting a price, explained the Book a meeting action, and offered a "Yes, book a meeting" button once it had our details. That is the HubSpot pattern: collect the contact first, then offer the calendar.SourcesHubSpot ↗

Booking runs through a meetings link, with conditions. Chatbots share a HubSpot meetings link; the customer agent can route qualified leads to a meeting link. HubSpot's help page lists what has to be true for the booking to stay inside the chat: the link asks only for name and email, those are collected earlier in the flow, the link has times available soon, and CAPTCHA and the data privacy switch are off. With custom form fields, the visitor is sent to the booking page instead.SourcesHubSpot +1 ↗

You write and tune the openings yourself. HubSpot's chatbot and customer agent guides describe welcome messages and greetings you write and target to pages; they do not describe testing different openings or replacing them automatically. Improving them means running your own comparisons.SourcesHubSpot +1 ↗

The AI agent is built for support first. It is named and priced as a customer agent, charged per resolved conversation, and lead qualification is an action you add to it rather than its main job.SourcesHubSpot ↗

Sales chat is one feature inside a large platform. That is its strength when you already run HubSpot, and its cost when you do not: the seats, onboarding and credits are priced for the whole hub, not for the chat.

HubSpot charges in two layers. Seats pay for the hub, and HubSpot Credits pay for AI work such as the customer agent.SourcesHubSpot ↗

• Free tools: $0/mo, with live chat and a rule-based bot.SourcesHubSpot ↗
• Sales Hub Starter: $20/seat/mo, which removes HubSpot branding but does not include the customer agent.SourcesHubSpot ↗
• Sales Hub Professional: $100/seat/mo, plus a one-time onboarding fee of $1,500.SourcesHubSpot ↗
• Customer agent: $0.5/resolved conversation.SourcesHubSpot +1 ↗
• Extra credits: $10/1,000 credits.SourcesHubSpot ↗

Take a team of 3 on Sales Hub Professional, billed monthly. Seats come to $300 a month, and with the onboarding fee the first year costs $5,100 before any credits. Professional includes 3,000 HubSpot Credits; Starter includes no customer-agent usage. The customer agent uses 50 HubSpot Credits per resolved conversation. So the included credits cover 60 resolved conversations a month, if nothing else in the account uses them. If the agent resolves 200 conversations in a month, the other 140 cost about $70 in extra credits.SourcesHubSpot +2 ↗

Three costs are easy to miss. The onboarding fee is required on Professional. Credits are shared with every other Breeze feature in the account, so the agent may not get the full allowance. HubSpot's included monthly credits refresh each month, and unused ones expire rather than carry over. And a resolved conversation is a support outcome, not a booked meeting, so price the agent against the questions it closes.SourcesHubSpot ↗

On your website. A HubSpot website chatbot runs inside HubSpot's chat widget, which loads with HubSpot's tracking code. On a site HubSpot hosts, the code is already there. Anywhere else, you paste it before the closing body tag on every page, and the bot will not appear on pages without it. HubSpot has an official WordPress plugin, HubSpot All-In-One Marketing, that adds its live chat and chatbots to a WordPress site.SourcesWordPress.org ↗HubSpot ↗

In your CRM. This is the integration HubSpot does best, because there is nothing to connect. Bot answers become contact properties, conversations sit on the contact record in the inbox or help desk, and bookings land on the rep's HubSpot calendar. The Target tab can even show one bot to known contacts and another to first-time visitors.SourcesHubSpot ↗

With another chat tool. If you are comparing AI chatbot platforms that integrate with HubSpot, read what "integrate" means on each vendor's help pages, because it ranges from a full sync to a file you import. Intercom's HubSpot app sends new leads and their conversations from Intercom to HubSpot, one way. Intercom's Fin for Sales can also book meetings with HubSpot's scheduler. At the other end, some chat tools have no sync at all: you export follow-up contacts as a CSV and import them into HubSpot yourself, and the conversation itself never reaches the contact record.SourcesIntercom +1 ↗

Before you buy any chatbot for HubSpot, ask three questions. Does it create or update the HubSpot contact? Does it log the conversation on that contact? And does a booked meeting show up on the HubSpot record, or only in the chat tool's own reports?

If the main job of your website chat is booking sales meetings, Darwin is a better fit than HubSpot's chatbot, because that is the one job we built it for. It answers a visitor's questions from your own website, offers a meeting when the questions show buying interest, and lets the visitor pick a time inside the chat through Calendly, Google Calendar or RevenueHero.SourcesDarwin +1 ↗

If you are weighing the AI chatbot HubSpot sells against a tool built for that job, four differences decide it.

• Booking is the main path, not an action you add. In HubSpot, times show inside the chat only when the four conditions above hold. Darwin collects the details it needs in the conversation and shows the times in the chat with each of its three calendar providers.SourcesDarwin ↗
• It improves its own openings. Of the 31 website chat and AI SDR tools we have checked, Darwin is the only one whose documentation describes testing its own chat openings on live traffic, keeping whichever brings more visitors to the booking step, and starting the next test from that winner, with no one setting the tests up. HubSpot's guides describe welcome messages you write and target yourself.SourcesDarwin ↗HubSpot ↗
• It sets itself up from your site. From your website it drafts its knowledge, picks up your brand colors and fonts, and writes the first opening for each page; you review the draft and paste one script.SourcesDarwin ↗
• You pay per meeting, not per seat or per answer. Free costs $0/mo. After 5 free credits, included once, Free charges $30/credit. Paid plans start with Growth at $299/mo.SourcesDarwin ↗

The testing idea is the one Darwin is named after. Natural selection needs variation, a fair test and a way to keep what works. Darwin writes new openings for a page, shows them to real visitors next to the current one, keeps whichever brings more people to the booking step, and starts the next round from that winner. With automatic testing on, it runs that loop without anyone setting up the tests.SourcesDarwin ↗

A worked example: a team that books 10 meetings a month through the chat pays $300 for that month on Free once the free credits are used, or $299 on Growth, which includes 10 credits a month and charges a lower rate for each extra one. Extra credits cost $25 each. Choosing more credits each month lowers the rate: on Growth, $20 at 35 credits, $16 at 60 and $12 at 110; on Agency, $10 at 275 and $8 at 525. On HubSpot, the AI customer agent needs Professional seats before it runs; for three people that is $300 a month before credits, although those seats also buy the rest of Sales Hub.SourcesDarwin ↗

Choose something else when the job is different. If every chat must land on the HubSpot contact record automatically, keep HubSpot's own chat, because our follow-up runs through a CSV export. If the job is support with an inbox and tickets, use HubSpot's customer agent or Intercom; Darwin is not a help desk. Darwin does not identify the people or companies visiting your website; it talks with the visitors who open the chat. If naming the companies behind anonymous visits matters most, look at Warmly or HubSpot's buyer intent. And if you need outbound email sequences, you want an AI SDR, not a website chat.SourcesDarwin +1 ↗

Prices are on our pricing page, the feature-by-feature comparison is on Darwin vs HubSpot, and how Darwin improves its openings explains the testing loop in our docs.

Keep it if your team works in HubSpot every day and the chat's main job is answering questions and capturing contacts: no other tool gets conversations onto the HubSpot contact record with less work. Look at another tool in three situations. The job is booking sales meetings and you do not want Professional seats to get AI answers. You need something HubSpot's chat does not do, such as naming the company behind an anonymous visitor. Or your CRM is not HubSpot.

We chose the five tools below from those we have reviewed against the same criteria: what each is built for, whether it books meetings inside the chat, how it learns about your business, and how it charges. They are ordered by how well they suit a HubSpot customer, and we did not trial each one.

• Intercom, if support is the bigger job. Its AI agent, Fin, answers from your help content, and Fin for Sales can book meetings with HubSpot's scheduler. On 12 May 2026 Intercom renamed the company Fin; Intercom remains the name of its customer service platform. Seats on its Essential plan cost $39/seat/mo.SourcesIntercom +2 ↗
• Warmly, if you want to know which companies are visiting. It names the companies behind anonymous visits and adds an inbound chat. Warmly books meetings directly in the chat, through Google Calendar, Outlook or Chili Piper links. On 30 June 2026 Warmly announced an agreement to be acquired by HubSpot; it says existing contracts, pricing and integrations stay unchanged for now. Its plans start at $10,000/yr.SourcesWarmly +3 ↗
• Darwin, if the job is booking sales meetings and you want to set it up yourself. Our pick for that job, covered in full above: times inside the chat, openings that test themselves, and a bill that follows booked meetings. For a HubSpot team the trade-off is follow-up through a CSV export rather than an automatic sync. Darwin vs HubSpot.SourcesDarwin +1 ↗
• Tidio, for a small business or store on a budget. It pairs live chat with an AI agent, Lyro. Lyro learns from website URLs pasted as data sources. Its paid plans start at $29/mo, with Lyro billed separately.SourcesTidio +1 ↗
• Qualified, only if you also run Salesforce. Piper is an enterprise AI SDR, and its own chat told us Qualified requires Salesforce CRM, so HubSpot alone will not do. Salesforce completed its acquisition of Qualified, the maker of Piper, on 1 April 2026.SourcesQualified ↗Salesforce ↗

For a HubSpot customer, the free rule-based chatbot is the easiest chatbot to justify: it costs nothing, needs no other vendor, and every answer ends up in the CRM. The customer agent makes sense for support teams already on Professional, and its per-resolution price is easy to forecast once you know your volume. It is a weaker fit for booking-first sales chat, where meetings depend on a link and on flows you maintain by hand, and for anyone not already paying for HubSpot.

If the job is booking sales meetings from your website, Darwin is the better fit: visitors pick a time inside the chat, the openings test and improve themselves, and you pay per meeting rather than per seat. Keep HubSpot's chatbot for support, for contact capture, and for teams that need every conversation on the HubSpot record without an export.
