The best AI chatbots for websites in 2026

A visitor lands on your pricing page at 11 at night with one question. Either something that has read your whole site answers in a few seconds, or a contact form waits until morning, and by then they've bought elsewhere. Picking the best AI chatbot for your website in 2026 comes down to three things: where its answers come from, how you pay for them (per seat, per answer or a flat plan), and what happens when it doesn't know.

We checked nine of them on their own pricing and product pages on 4 November 2026. One of them is ours, crew bot. It sits where it honestly fits, with the small-business options, and its limits are listed like everyone else's.

The short answer

• You already run a help desk with a support team: Fin or Zendesk.
• Your customers already live in HubSpot: HubSpot's Customer Agent.
• You're a small business on a tight budget: tawk.to or Tidio.
• You want the chat, visitor analytics without cookies, and a crew that does other work, in one place: crew bot.
• You want to build your own agent that takes actions: Chatbase or Botpress.

How an AI website chatbot works

Almost every product here works the same way underneath. It reads your content (website pages, help articles, documents), splits it into passages, and for each question finds the passages that match best. A language model then writes a short answer from those passages. That's called retrieval: the bot isn't recalling your prices from memory, it's looking them up.

What separates a good one from a bad one:

• It says when it doesn't know. A bot that guesses a refund policy is worse than no bot.
• It shows its sources, so a visitor can check and your team can fix the page if the answer was wrong.
• It hands over cleanly to a person, with the conversation so far.
• Its price doesn't punish success. Some charge per resolved conversation, some charge per message, some include AI in a flat plan.

Full help desks with an AI agent built in

1. Fin, from the makers of Intercom

Who it's for: companies with a support team, especially those already on Intercom's help desk. Fin also plugs into other help desks, including Salesforce, HubSpot, Zendesk, Freshworks and Gorgias.

Who makes it: the company called Intercom renamed itself Fin in 2026, and Salesforce completed buying it on 10 September 2026. The help desk is still sold as Intercom.

How its AI works: Fin is trained on your policies and procedures, and handles multi-step work through what it calls Procedures: it can update accounts, process refunds and troubleshoot, reaching your systems through APIs, data connectors or MCP. It answers on chat, email, voice, Slack and social channels, in dozens of languages, and hands over to your team with the context. Fin's own figure is an average resolution rate of 76% across more than 12,000 customers.

Price: $0.99 per outcome. An outcome is mostly a resolved conversation, though a few other events count too, and a qualified lead costs $9.99. Intercom seats are $29 for Essential when billed annually (shown at $19 for new customers when we checked), $85 for Advanced and $132 for Expert. Using Fin with another help desk needs no seats but has a minimum of 50 outcomes a month. There's a 14-day free trial.

Strength: the most capable at doing things, not just answering: refunds, account changes, many channels.

Limit: the bill grows with every success. A thousand resolved conversations is $990 a month before any seats.

2. Zendesk

Who it's for: larger support teams that already run their tickets in Zendesk.

How its AI works: connect your help center and outside sources such as Google Drive or PDFs. Zendesk says its AI agents speak 80 languages, work across web, mobile, social, voice and email, and route to the right team with the context when a person is needed.

Price: Suite Team is $55 an agent a month billed annually ($69 monthly) and includes 5 automated resolutions per agent a month. Suite Professional is $115 ($149 monthly) with 10. More resolutions cost $1.50 each when committed in advance, or $2.00 pay-as-you-go. The Copilot add-on for agents is $50 an agent a month, billed annually, on Professional and up.

Strength: mature ticketing, reporting and channels for a team that lives in tickets all day.

Limit: you pay twice, per agent and per resolution. A three-agent Team plan includes 15 automated resolutions a month, so most of the AI's work is billed on top.

3. HubSpot Customer Agent

Who it's for: businesses whose customer records already live in HubSpot.

How its AI works: the agent learns from your knowledge base, website, CRM data and past conversations, plus files you upload. It answers on chat, email, forms and phone calls, and on WhatsApp and Facebook Messenger, in every language HubSpot supports, and passes the conversation to your team with its context.

Price: $0.50 per resolution on messaging and $0.50 a minute on voice, paid in HubSpot Credits. HubSpot counts a resolution when the agent helped and nobody handed the conversation to a person for 72 hours. You need a Professional or Enterprise subscription: Service Hub Professional starts at $90 a seat a month, plus a one-time onboarding fee of $1,500.

Strength: answers that know who the customer is, from the CRM.

Limit: the entry cost. You're buying Professional seats and onboarding before the first answer.

Chat for small businesses, with AI

4. Tidio, with Lyro

Who it's for: small businesses and online shops that want chat, email and social messages in one place.

How its AI works: Lyro reads your support content automatically and answers only from that content and the guidance you give it. When the answer isn't there, it forwards the question to a person. Tidio says its customers average a 75% resolution rate with Lyro.

Price: a Free plan covers 50 conversations and your first 50 Lyro conversations (once, not monthly). Starter is $29 a month ($24.17 billed yearly) and Growth starts at $59. Lyro on its own starts at $39 a month for 50 conversations ($32.50 billed yearly), in bundles up to 1,000 a month.

Strength: quick to start, with Messenger, Instagram, WhatsApp and email even on the free plan.

Limit: Lyro's entry bundle works out at about 78 cents a conversation, and the bundles are small, so a busy month means a bigger bundle.

5. Crisp

Who it's for: small teams that want one shared inbox for chat, email and social, priced per workspace instead of per seat.

How its AI works: it learns from your knowledge base, a crawl of your website, question-and-answer snippets you write, past conversations and uploaded files such as PDFs. You can set a confidence level so it holds back answers it isn't sure of. It works on your web chat, WhatsApp, Messenger, Instagram and email.

Price: Free has 2 seats and no AI credits. Mini is $45 a month per workspace with 4 seats and $5 of AI credits, which Crisp puts at around 90 automated conversations. Essentials is $95 with 10 seats and $25 of credits (around 450), and lists the AI chatbot. Plus is $295 with 20 seats and $75 of credits (around 1,350). VAT is extra.

Strength: flat pricing per workspace, so adding a teammate doesn't raise the bill.

Limit: the AI allowance on the lower plans is small, and the AI chatbot is listed from Essentials up.

6. tawk.to, with AI Assist

Who it's for: small businesses and side projects that want live chat for free.

How its AI works: AI Assist answers from your FAQs, help center, website and documents, and hands over to a person.

Price: the live chat is free. AI Assist has a free Hobby plan with 100 message credits a month, one AI agent and up to 100 crawled pages. Growth is $29 a month ($290 a year) for 1,000 credits, Business $99 for 5,000 and Enterprise $399 for 20,000. Extra credits cost $30 per 1,000. Removing "Powered by tawk.to" is $29 a month.

Strength: free live chat, a free AI tier on top, and paid AI from $29 a month.

Limit: credits are counted per message, not per conversation, and the free tier's 100 messages go quickly on a busy site.

7. crew bot

Who it's for: small businesses and teams with one or more websites who want the chat, visitor analytics and a crew that also handles email, routines and servers, in one workspace.

How its AI works: you paste one line into your site. crew bot reads up to 150 of its pages, then writes an overview of the business and 15 to 60 questions visitors ask, each answered from and linked to its page, so nobody fills the knowledge in by hand. Your team's own answers come first when they match. The bot answers in seconds, in the language the visitor writes in, with the pages it used shown underneath. When the knowledge doesn't answer, it says so and offers a person: it never invents prices, dates, discounts or promises. A visitor waiting for a person shows in Needs you and sounds an alert, and your team gets an email if nobody replies within two minutes. The bot itself has no tools, so whatever a visitor types can, at worst, produce an odd reply, never an action.

Price: Free to start, then Start $19, Growth $49 and Scale $149 a month per workspace. Replies come out of the plan's AI allowance, measured at what the AI providers charge with no markup, and each site has a monthly spending cap, 10 US dollars by default.

Strength: analytics of visits and pages without cookies, with robots counted apart; many sites in one workspace, each with its own bot; an analytics-only mode for sites that want the figures and no chat.

Limit: it's a website chat only, not WhatsApp, Instagram or email. The bot can't look up an order or issue a refund: by design, anything that changes something is done by a person. And it's a newer product from a smaller company than most on this list.

More: what crew bot's support chat does, or compare it directly with Intercom Fin and Tidio.

Build your own AI agent

8. Chatbase

Who it's for: teams that want a custom agent that takes actions, without running servers.

How its AI works: connect your data sources, define the agent's role and set guardrails. You write procedures in plain language, with actions such as order status lookups, invoices, bookings or plan changes. You can pick the model from several AI labs, and deploy to your website, WhatsApp, Messenger, Slack, email or voice, with a help desk where the AI and your team share conversations.

Price: there's no free plan, but every paid plan has a 7-day trial. Hobby is $40 a month ($32 billed yearly) with 700 message credits, Basic $150 ($120) with 4,000, and Business $500 ($400) with 15,000.

Strength: flexible, with real actions and a choice of models.

Limit: credits are spent per request to the model, so an answer that triggers an action costs at least two. The step from Hobby to Basic is $40 to $150.

9. Botpress

Who it's for: developers and agencies building agents to their own design.

How its AI works: you build the agent; Botpress provides the conversations, storage for tables, knowledge and files, and the model calls, which it sells at cost.

Price: Free gives 100 conversations a month, 3 seats and 3 agents, with no overages. Plus is $150 a month billed annually, with 250 conversations and $25 of AI usage (more conversations at $65 per 100). Team is $750 a month billed annually, with 1,500 conversations and $150 of AI usage ($50 per 100 more).

Strength: control, and AI usage without a markup.

Limit: it's a building platform. Someone has to design, test and maintain the agent.

What about Drift?

Drift used to be on every list like this one. Its owner's page now reads "We've transitioned from Drift to 1mind", and no pricing is published, so we've left it out.

How to choose the best AI chatbot for your website

1. Start from where your support already lives. If your team works in Intercom, Zendesk or HubSpot, their own agent will fit with the least work. If you have no help desk yet, a small-business chat (or crew bot) is the faster start.

2. Do the cost math at your own volume. Say the AI fully resolves 600 conversations a month:

Per-answer prices buy capability; flat plans buy predictability. Neither is wrong, but know which one you're signing.

3. Test it on your real questions. Feed it your 20 most common questions. Then ask something your site doesn't cover. The right answer is "I don't know, let me get someone", not a confident guess.

4. Check the handoff. Ask for a person. How fast does your team hear about it, and does the visitor get the reply by email if they leave?

5. Decide what it may do. A bot that can issue refunds is powerful, and it's also exposed to anyone who types into it. Read prompt injection, and how to stay safe before you give a public chatbot tools.

6. Mind the privacy side. Many chat widgets set cookies. If you'd rather not, look for one that doesn't, and see what cookieless analytics can measure.

Will an AI chatbot make up answers?

It can, if it's built to always answer. The better ones answer only from your content, show the pages they used and say plainly when they don't know. Test this yourself with a question your site doesn't answer.

What's the difference between live chat and an AI chatbot?

Live chat connects a visitor to a person on your team. An AI chatbot answers on its own, day and night, from your content. Most products now do both: the AI answers first and hands over to a person when it should.
