Wix chatbot options, from Smart Chat to custom code

Wix has a chatbot of its own, Wix Smart Chat, which answers visitors from your site and runs on Wix’s AI credits. You can also install an AI chatbot from the Wix App Market, or paste another company’s script into your site’s Custom Code, which needs a Premium plan and your own domain. We read Wix’s help centre, its developer docs and the App Market on 23 September 2026, and tested live Wix sites the same day.

Deacon is an AI customer support agent that goes onto a Wix site as one snippet in Custom Code. It answers your customers in seconds from your own pages, and it shows you what they ask about most, so you know what to fix and what to build. The free plan gives you 50 answers a month, needs no card and has no end date.

Wix Smart Chat, and what it costs

Wix Smart Chat is Wix’s own app. It answers visitors with AI, lets you reply by hand from your Wix Inbox, and can mix the two on a schedule. Wix’s help centre says it replaced Wix AI Site Chat for new sites in March 2026, and the older Wix Chat is on its way out too.

The app is free to install, and the manual chat is free to use. The AI chat runs on AI credits rather than a Smart Chat subscription of its own. Wix’s page on Smart Chat and AI credits says three things a founder should know first.

• The credits are shared. The same balance pays for Wix’s other AI tools, such as its AI Marketing Agent and Wixel, so a month of marketing work leaves less for the chat.
• The allowance is an estimate. Wix’s page on AI credits puts Smart Chat at up to 150 actions a month on Light and up to 1,000 on Business Elite, and says the numbers aren’t guaranteed. A free site gets credits that reset daily, up to 120 a month.
• When the credits run out, the chat goes offline, unless you switch it to manual chat and answer everything yourself.

On the day we looked, Smart Chat was rated 2.7 out of 5 from 153 reviews on the App Market.

AI chatbots from the Wix App Market

The App Market’s Chat category listed 131 apps on 23 September 2026, and many of them are WhatsApp and social buttons. Here are Wix’s own chatbot and the two AI chatbots for websites with the most reviews, from their listings and their own pricing pages that day. Prices on the App Market change with your country, so the table sticks to what each app gives you free.

Each counts something different. Chatway counts AI conversations, Ultimo Bots counts AI responses and Smart Chat spends credits. Deacon counts answers, one per reply, and a conversation takes about 2 of them, so 50 answers covers about 25 conversations.

Where a chatbot’s code goes on Wix

A chatbot that isn’t an App Market app goes in through Custom Code, in your site’s dashboard. Wix’s guide to custom code starts with a condition. The site must be published and have a connected domain, and Wix’s page on domains says you need a Premium plan before you can connect one. A free site on a wixsite.com address gets no Custom Code.

With both in place, the steps are the same for any snippet.

1. In your site’s dashboard, go to Settings and click Custom Code, under Development & integrations.
2. Click + Add Custom Code and paste the snippet.
3. Give it a name you’ll recognise.
4. Under Add Code to Pages, choose All pages, and load it on each page your visitor opens.
5. Under Place Code in, choose Head, Body – start or Body – end, as the snippet’s maker says.
6. Click Apply, then open your live site.

Wix’s developer page on custom code says the same Custom Code works in every Wix editor, Wix Studio included. It also says custom code doesn’t take effect in the editor and only runs on the published site, so check there.

The Wix sites we tested reload on every link

On 23 September 2026 we followed links on three Wix sites, two on their own domains and one on wixsite.com. Each time the browser loaded the next page from scratch, even with a real mouse click. That’s why the step above loads the code on each page. A snippet has to start again on every page, and a chatbot has to remember where the visitor was.

Wix’s security rules for third-party code

In December 2025 Wix brought in frontend security rules for all custom code, and its guide warns that some snippets that used to work may now be blocked. Wix’s page on frontend security lists what changed. Frames on the site’s own domain are sandboxed, an iframe’s srcdoc is blocked, and core objects such as JSON and URL can’t be modified. For a frame that talks to the page, its advice is a cross-origin iframe using postMessage.

When you change your domain

Wix ties each snippet to one domain. If you assign a different domain to your site, the guide says your snippets are deleted, so paste the chatbot’s code in again afterwards. A secondary domain needs nothing, because Wix sends its visitors to your primary domain.

What Deacon does on your Wix site

Most of what people ask, your pages already answer. They don’t find it, so they ask you, and every repeat question costs you time you’d rather spend building. Deacon answers them in seconds, at any hour, from the pages you choose and in whatever language each customer writes. An answer taken from one of your pages often links to it.

When your pages don’t cover a question, Deacon says it doesn’t know rather than guessing, and asks for the visitor’s email. If they leave it, or ask for a person, you get an email. Reply from Deacon’s dashboard, and if the visitor still has the chat open, your reply appears there under your name.

Then Deacon gets better. Every question your pages didn’t cover waits in the dashboard with an Answer this button. What you write becomes part of what Deacon knows, so it can answer the next person who asks, and over time it needs you less.

You also learn what your customers need, from everyone who asks rather than the few who email. Every conversation is saved and searchable by what visitors asked. Topics groups the questions, counts how many people asked and labels most of them, such as a how-to, a feature ask or a bug report. The same snippet counts your visitors, where they came from and the goals they reach, on Analytics › Website.

Deacon also fits the way Wix works. Its chat panel loads from Deacon’s own domain and talks to your page with postMessage, the kind of frame Wix’s security rules point to. When a Wix site loads the next page from scratch, Deacon carries the chat across. A visitor who follows a link with the chat open finds it open again on the next page, at the same size, with the conversation in it. And if you ever move your site off Wix, Deacon moves with you, with the same snippet on the new site.

Every feature is on every plan, the free one included, and there’s no badge to pay to remove. Deacon’s answers don’t share a balance with anything else, and every plan answers with the same model, so no credits run out faster on a better one. Nothing is billed past your plan’s answers, and no plan upgrades itself. The pricing page has the paid plans.

Adding Deacon to Wix

Deacon isn’t an App Market app, so it goes in through Custom Code. The snippet it gives you looks like this, with your own key in place of the placeholder.

<script src="https://heydeacon.com/widget/v1/loader.js" data-key="pk_your_widget_key" async></script>

It takes a few minutes on a site with a Premium plan and a connected domain.

1. Sign up with your email or Google, and give Deacon your site’s address. The free plan needs no card. There’s nothing to tick. Deacon chooses your pages, learns from them and starts answering.
2. On the Install page, check the domain connected to your Wix site is listed, and add it if it isn’t. The website you gave when you signed up is already there, with your snippet ready, and it covers your address with or without www. It covers your subdomains too, so if Wix Multilingual puts your languages on subdomains, such as fr.yoursite.com, Deacon shows there with nothing more to add.
3. In Wix, add the snippet in Settings › Custom Code, on all pages, loaded on each page, and placed at Body – end. Click Apply.
4. In Knowledge Sources, untick any page Deacon shouldn’t use. If Wix Multilingual uses its default subdirectories, such as /fr, a crawl of your whole site on a paid plan leaves those copies out, and Deacon still replies in each visitor’s language.
5. Ask it your customers’ questions in the Playground before anyone else sees it.

What to check after you apply the code

These five checks take a couple of minutes.

1. Open your live site in a private window. The Wix editor and its preview never run custom code.
2. Open the chat, ask something and follow a link. The chat should open again on the next page, with your question still in it.
3. Look at the top of the Install page. It says whether Deacon is live on your site and when it was last seen, and it keeps checking by itself.
4. Ask one question your pages answer and one they don’t. The first should get an answer, and the second an honest “I don’t know” with a box for an email address.
5. If you ever change your site’s domain, come back to Custom Code. Wix deletes the snippet with the old domain, so paste it in again and add the new domain on Deacon’s Install page.

Questions about Wix chatbots

Does Wix have its own AI chatbot?

Yes. Wix Smart Chat answers visitors with AI and lets you reply by hand. It’s free to install, and its AI replies spend AI credits from your Wix plan, shared with Wix’s other AI tools. When the credits run out, it goes offline unless you switch to manual chat.

How much does Wix’s AI chatbot cost?

There’s no separate price. Smart Chat uses the AI credits in your Wix plan, and Wix estimates up to 150 Smart Chat actions a month on Light and up to 1,000 on Business Elite, without guaranteeing either. A free Wix site gets up to 120 credits a month, reset daily.

Can I add a chatbot to a free Wix site?

Only an app from the App Market, such as Smart Chat, and some of those say Premium Site Required. A snippet in Custom Code needs a published site with a connected domain, and connecting a domain needs a Premium plan.

Does this work on Wix Studio?

Yes. Wix’s developer docs say Custom Code works in every Wix editor, and Wix Studio sites add it from the same Settings › Custom Code page.

Should I load the code once per visit or on each page?

On each page, for Deacon. The Wix sites we tested loaded every page from scratch, so the snippet needs to start on each one. Where a copy is already running, a second one does nothing.

What happens when Deacon’s free answers run out?

Deacon doesn’t go offline. A visitor who asks gets a short reply saying Deacon can’t look into that one right now, and is asked for an email unless they’ve already left one in that conversation. You can still read and reply to every conversation, nothing is billed and your plan doesn’t upgrade itself.
