AI Chat Widget for Wix

How to add an AI chat widget to Wix

This is the one Wix install where the method isn’t a preference. Embed HTML is a sandboxed iframe with no direct access to the page around it, so a floating launcher placed there is pinned to the frame: stuck inside the rectangle you drew, unable to overlay the header or footer, and gone when the visitor changes page. Settings → Custom Code puts the snippet into the real page instead, and Wix offers it only on a published site with a connected domain.

1. In Sorraia, add the website and verify it — a DNS TXT record, or a meta tag in your homepage’s <head>. Verification is what lets you attach a widget to that site, so it comes before there is anything to paste.

2. Save the agent, then copy the snippet from the Embed code box in the right-hand panel of the chat builder. (Chat has no install wizard — the box is the whole thing.)

3. Publish the site and connect your own domain first — Wix offers Custom Code only on a published site with a connected domain.

4. In the site dashboard, go to Settings → Custom Code (in the Development & integrations section) and click + Add Custom Code.

5. Paste the Sorraia snippet, give it a name, and under Add Code to Pages choose All pages, loading the code once per visit.

6. Under Place Code in, choose Body – end, then click Apply. Custom code doesn’t run in the editor, so open the published site to see the launcher.

Worth knowing for this one

• Custom Code is added from the site dashboard, so it works the same whichever editor built the site — Wix Editor, Studio or Harmony — and it runs only on the published site, never in the editor.²
• In December 2025 Wix introduced frontend security measures for custom code that block some operations outright, so re-test the live site after adding the snippet.¹⁶
• Wix ties each Custom Code snippet to the site’s domain and deletes it if the domain changes, so re-add the chat after moving a client to a new domain.¹
