Wix chatbot on a published site with a connected domain

Wix has a chatbot of its own. Wix Smart Chat replaced Wix AI Site Chat for new sites in March 2026, and it answers visitors from your site’s pages. Deacon is a second option, added as a snippet of code. You can run it free for up to 50 answers a month.

Custom Code needs a connected domain

Wix’s guide to embedding custom code, which we read on 19 September 2026, starts with a condition. The site must be published and have a connected domain. A connected domain needs a paid plan, says Wix’s page on domains. Free-plan sites get no Custom Code.

With both in place, the steps are in the site dashboard.

1. Copy the snippet from Deacon’s Install page, after adding your Wix domain to the list there.
2. In the Wix dashboard, go to Settings and click Custom Code, under Development & integrations.
3. Click + Add Custom Code, paste the snippet and name it Deacon.
4. Choose All pages, and the last of the three placements, at the end of the body.
5. Click Apply, then open your live site to check.

Wix also asks whether to load the code once per visit or on each page. Choose each page. Deacon’s loader notices a copy already running and does nothing the second time.

Wix’s rules for third-party scripts

In December 2025 Wix brought in new security rules for all custom code. Its custom code guide warns that some snippets that used to work may now be blocked. Wix’s developer page on frontend security lists them. Frames on the site’s own domain are sandboxed, and an iframe’s srcdoc attribute is blocked. Its advice is a cross-origin frame that talks to the page with postMessage.

Deacon’s chat panel is that kind of frame. It loads from Deacon’s own domain, whatever the domain of your site.

Custom code never runs in the Wix editor, only on the published site, as the developer page on custom code says. Check Deacon on your live domain. Wix’s support team does not help with problems in third-party code.

What Wix Smart Chat costs

Smart Chat is free to install and comes with a trial of 50 conversations. It now runs on AI credits instead of a subscription. How much it can do depends on your Wix plan, and the same credits pay for Wix’s other AI tools. Wix’s page on AI credits estimates up to 150 Smart Chat actions on Light and up to 1,000 on Business Elite. It says the numbers are not guaranteed.

The manual side of Smart Chat, where you type the replies yourself, is free to use, according to Wix’s page on moving to Smart Chat.

What crawlers read on a Wix page

Wix builds each page on its servers before sending it. Wix’s guide to viewing page source says most AI crawlers run no JavaScript and read only the HTML the server sends. Script-added content stays invisible to them.

So prices, delivery times and anything else you want found belong in the text of a page. The same guide shows how to view a page the way a crawler does.

Changing your site’s domain

Wix ties each code snippet to one domain. Assign a different domain to your site and the snippets are deleted, as the custom code guide says. After a switch, paste Deacon’s snippet again. Then put the new domain on the list the install guide shows you how to edit.
