Best AI chatbots for websites in 2026: 12 tools compared

This guide covers one job: an AI chatbot on your website that answers visitors from your own content. On October 7, 2026 we read each vendor's pricing page (and help center where needed) and compared:

• How it learns your content: a website crawl or import, file uploads, text and Q&A, and whether it re-reads your site when it changes.
• Whether it sticks to your content: answering only from what you gave it, and saying so when the answer isn't there.
• Install: a script tag, a WordPress plugin, or an app for a site builder.
• Languages the chatbot answers in.
• Free plan, entry price and billing unit: conversations, messages, credits or page views, and whether each price is billed monthly or annually.
• Branding removal: what it costs to hide the vendor's "Powered by" link.

We didn't run an accuracy test on every tool, so the tables show what each vendor says. The checklist at the end shows how to test answer quality yourself.

• A local or service business site (plumber, salon, clinic, restaurant, hotel): Nexoply. It imports your services and prices and answers only from them, with the AI included in every plan.
• A large site, help center or documentation: SiteGPT, for its source list and 1,000 pages on the entry plan.
• You want to build and tune the bot yourself: Chatling (generous free plan, many AI models) or Chatbase (many channels and actions).
• Someone on your team also answers chats: Tidio for shops, tawk.to for free live chat.
• You already collect forms: Jotform AI Agents, which can fill a form during the chat.
• You want visitors to choose WhatsApp, phone or chat: Boei.
• Smallest possible paid budget: Elfsight, from $5 a month billed yearly, if your traffic is low.

Nexoply is built for one job: answering visitors on a small business website. You type in, or import from your site, your services and prices, FAQs, policies, opening hours and service areas. The import reads your public pages, including JavaScript-built ones, and adds nothing until you approve it. The assistant answers only from that information, says so when it doesn't know, and can send visitors to the right page.

• Pricing: Free with 50 conversations a month and no credit card. Starter $19, Business $49 and Pro $99 a month billed monthly, or $190, $490 and $990 billed yearly (two months free). The AI is included in every plan. Removing "Powered by Nexoply" is included from Business. See pricing.
• Strengths: website import (15 to 200 pages per scan by plan); 12 languages, answered in the visitor's language; one script tag on any site; the widget loads asynchronously, sets no cookies and can't break your site; unanswered questions become FAQs in one click; built-in spam protection.
• Considerations: it's a website assistant only. There's no live-chat inbox for your staff, no WhatsApp, Instagram, email or phone channel, no order tracking, and it doesn't take bookings or payments (it links to your booking page, phone or WhatsApp). One chatbot per business. There's no WordPress plugin, Shopify app or Wix app: you paste the script tag once.
• Best for: plumbers, salons, clinics, restaurants, hotels and gyms whose visitors ask the same questions about prices, hours and policies. See features.

Chatbase builds an AI agent from the sources you add: a crawl of your website, files, text, Q&A pairs or Notion. You put it on your site with a chat widget and can deploy the same agent to WhatsApp, Slack, Messenger or Instagram, with actions and integrations.

• Pricing: Free with 50 message credits a month, 1 agent and 1 MB of training data; free agents are deleted after 14 days of inactivity. Hobby $40 a month billed monthly ($32 billed yearly) with 700 credits, Standard $150 ($120), Pro $500 ($400). Removing "Powered by Chatbase" is a $99/month add-on; extra agents are $25 each a month. Chatbase pricing.
• Strengths: many sources and channels, a choice of AI models, actions, many languages.
• Considerations: credits are per message and a conversation uses several, so 700 credits is not 700 chats; branding removal costs more than Hobby; more settings than a non-technical owner may want.
• Best for: businesses and agencies that want one agent across the website and messaging apps. See Nexoply vs Chatbase and Chatbase alternatives.

SiteGPT trains a chatbot on your website and documents. It reads links and sitemaps, YouTube videos, files (CSV, TXT, PDF, DOCX, PPTX, Markdown), text, Notion, Google Drive, Dropbox, OneDrive, Box and GitHub. It counts 2,500 cleaned characters of content as one page, and answers in any language.

• Pricing: no free plan; a 7-day trial with a credit card. Starter $59 a month billed monthly ($39 billed annually): 1 chatbot, 1,000 pages, up to 4,000 GPT-4.1-mini or 400 GPT-4.1 messages a month. Growth $129 ($79 annually): 2 chatbots, 10,000 pages, monthly auto-refresh. Branding removal is a $39/month add-on. SiteGPT pricing.

• Strengths: monthly free AI credits, over 80 languages, WhatsApp, Instagram, Messenger, Telegram and Slack on paid plans, 7-day money-back guarantee.
• Considerations: the cost per reply depends on the model, so credits aren't chats. No WordPress.org plugin; you use the embed snippet.
• Best for: owners and agencies who like to build and tweak their own chatbot.

Tidio is live chat and a helpdesk with an AI agent, Lyro. Lyro answers from the FAQs, website content and Q&A you give it, and passes the chat to a person when needed. Tidio also has automation flows and a multichannel inbox.

Tidio pricing.
• Strengths: people and AI in one widget, Shopify and other ecommerce integrations, flows, a multichannel inbox.
• Considerations: the AI is a separate add-on with its own meter, and the free AI allowance is one-off. If you only want the site to answer on its own, you also pay for a helpdesk.
• Best for: online shops and small teams with someone available to answer chats. See Nexoply vs Tidio and Tidio alternatives.

• Best for: clinics, schools and service businesses that take intake forms, quote requests or registrations.

Every tool above gets its knowledge in one or more of three ways:

• A website crawl or import: you enter your address and the tool reads your pages. Check how many pages your plan reads (Nexoply 15 to 200 per scan, tawk.to's free AI tier up to 100, SiteGPT 1,000 on Starter) and whether it re-reads them when your site changes (Chatling weekly or daily, Dante AI weekly or daily, SiteGPT monthly from Growth).
• Files and text: PDFs, Word documents, price lists and menus. Useful for anything that isn't on your website, such as a hotel's late check-out rules.
• Questions and answers you write: the surest way to control the exact answer to "How much is an emergency call-out?" or "Can I cancel 24 hours before?".

A crawler stores the text of each page; Nexoply's import also suggests services with prices, FAQs, policies and hours for you to approve, so an outdated page doesn't slip in unnoticed.

Then the chatbot should answer from that content only, and admit when the answer isn't there. Picture a salon that lists colour from $80 but never published a keratin price. A good chatbot says it doesn't have that price and offers the phone number; a weak one invents a figure. Test this yourself with the checklist below.

• A website AI chatbot answers on its own, from your content, at any hour. Nobody has to watch it. You pay per conversation, message or credit.
• Live chat connects the visitor to a person on your team. A person can handle anything, including unusual requests, but only while someone is there. It's usually priced per seat, though tawk.to's live chat is free.
• Both in one widget: Tidio, tawk.to, Boei and Wonderchat combine AI answers with people answering in the same widget. On tawk.to the handover to people starts on the paid Growth AI plan, and on Dante AI on Advanced.

A plumber under a sink or a hairdresser with a client can't reply to a chat window, so a chatbot that answers alone is practical. A shop with someone at a desk may want both. Nexoply is AI only: no inbox for staff; it points visitors to your phone, email, WhatsApp or booking page when they need a person.

1. 01

   Set the chatbot up first

   Add or import your content and test it on the vendor's preview page before it goes live.

2. 02

   Copy the embed code

   Almost every tool gives you one script tag. Nexoply's looks like this: <script src="https://nexoply.com/widget.js" data-chatbot="YOUR-KEY" async></script>.

3. 03

   Paste it once, on every page

   Put it just before </body>, usually in your site builder's footer code or custom code setting, so it appears site-wide.

4. 04

   Or use a plugin if there is one

   tawk.to, Jotform, Boei, SiteGPT, Dante AI and Elfsight have WordPress.org plugins that add the code for you. Nexoply has no plugin: on WordPress you paste the tag with a header and footer plugin such as WPCode.

5. 05

   Publish and check

   Open your site on a phone, ask a question, and confirm it appears in the dashboard.

Our install guides show where the code goes on each platform. They're written for Nexoply, but the same setting works for most script-tag chatbots:

• Add an AI chatbot to WordPress (and the best AI chatbots for WordPress)
• Add an AI chatbot to Wix: custom code needs a Wix premium plan with a connected domain
• Add an AI chatbot to Squarespace: code injection needs the Business plan or higher
• Add an AI chatbot to Shopify (and the best AI chatbots for Shopify)
• Add an AI chatbot to Webflow
• Add an AI chatbot to any HTML website
• For developers: React, Next.js and Vue or Nuxt

1. 01

   Test accuracy with 10 real questions

   Take them from your inbox or phone calls: a clinic's "Do you see new patients on Saturdays?", a restaurant's "Do you have a vegan menu?", a hotel's "What time is check-out?". Compare each answer with your own information.

2. 02

   Ask something it can't know

   For example a service you don't offer, or a price you never published. The right answer is "I don't have that information" plus a way to reach you.

3. 03

   Switch languages

   Ask the same question in the languages your customers use, and check the answer is correct, not just translated.

4. 04

   Price it at your traffic

   Estimate your chats per month and questions per chat, then check what each tool's unit means for you (see the table below).

5. 05

   Look at it on a phone

   Check the button doesn't cover your own buttons, the chat window is readable, and whether the vendor's branding shows on your plan.

6. 06

   Read the conversations

   Make sure you can see every conversation and spot questions it couldn't answer, so you can fill the gaps.

If you run a small business and want your website to answer visitors on its own, you can try Nexoply for free with no card: create a free account, enter your website address to import your services, prices and FAQs, ask your own test questions on a test page, then paste one line of code into your site.
