How to Add an AI Chatbot to Your Wix Website

A simple guide to adding the Factfu AI chatbot to any Wix site. No app install required — just paste a script tag in your site settings and you're live.

Why add a chatbot to your Wix site?

You built a beautiful Wix site. You picked the perfect template, tweaked the colors, uploaded your best photos. But when a visitor has a question at midnight — say, "Do you offer gift wrapping?" or "What's the difference between your Basic and Premium package?" — your site just... stares back at them.

Contact forms are great, but they're not conversations. And "We'll get back to you within 24 hours" isn't the answer anyone wants to hear when they're ready to buy right now.

An AI chatbot reads your actual site content and answers questions in real time. It's like having a knowledgeable team member available around the clock — except this one doesn't need coffee breaks.

What you'll need

A Wix website (any plan — free works too)
A free Factfu account
About 3 minutes

That's it. No coding, no Wix app marketplace — just a quick copy-paste.

Step 1: Set up Factfu

Go to factfu.com/signup and create a free account
Click Create Bot and give it a name
Add your content:
- Website URL — enter your Wix site address and Factfu will crawl your pages
- Text/FAQ — paste in any FAQs or info you want the bot to know
- Documents — upload PDFs, menus, or other materials

Pro tip: Feed it your "About" page, services page, and any FAQ content. That covers most questions people ask.

Step 2: Get your widget code

In the Factfu dashboard, go to Settings → Widget
Copy the embed code — it looks something like this:

<script src="https://factfu.com/v0/widget.loader.js"
  data-widget-key="pk_your_key_here"
  defer>
</script>

Keep this code handy. You'll paste it into Wix in the next step.

Step 3: Add the code to Wix

There are two ways to do this depending on your Wix setup:

Option A: Site-wide (recommended)

This adds the chatbot to every page of your site:

In your Wix dashboard, go to Settings (the gear icon in the left sidebar)
Click Custom Code (under "Advanced")
Click + Add Custom Code
Paste the Factfu embed code from Step 2
Name it "Factfu Chatbot" (just for your reference)
Under Add Code to Pages, select All pages
Under Place Code in, select Body - end
Click Apply

Option B: Specific pages only

If you want the chatbot on specific pages:

Open the Wix Editor for the page you want
Click Add (+) → Embed Code → Custom Code
Paste the Factfu embed code
Position the element anywhere (it won't affect the visible layout — the chat widget floats in the corner automatically)
Repeat for any other pages you want

Using Wix Studio?

If you're on Wix Studio (the newer editor):

Go to Site Settings → Custom Code
Click Add Custom Code at the top right
Paste the embed code
Set placement to Body - end and scope to All pages
Save

Step 4: Publish and test

Hit Publish on your Wix site. Visit your live site (not the editor preview) and you should see the chat bubble in the bottom-right corner.

Click it. Ask a question. Watch it pull the answer from your content.

That moment when it actually gets the answer right? Never gets old.

Customizing the look

The chatbot's appearance is controlled from the Factfu dashboard, not Wix. To match your site's style:

Go to your Factfu dashboard
Navigate to Bots → [Your Bot] → Customize
Set your brand colors (if your Wix site uses a blue theme, make the widget blue)
Upload an avatar — your logo works well
Set a welcome message: "Hi! How can I help you today?" or whatever fits your brand
Add quick reply buttons for common questions

Changes apply instantly — no need to update anything in Wix.

Troubleshooting

Widget doesn't appear after publishing:

Make sure you published your site after adding the code
Check that the custom code is set to load on Body - end
Try viewing your published site in an incognito window (Wix caching can be aggressive)
Verify the widget key in your embed code matches the one in your Factfu dashboard

"Custom Code" option isn't showing:

Custom code is available on Wix Premium plans. If you're on the free plan, you'll need to upgrade to use custom code injection
On Wix Studio, the option might be under a different menu — check Site Settings → Custom Code

The widget appears but doesn't know my content:

Make sure you've added content sources in your Factfu dashboard
If you added your Wix URL as a source, wait a few minutes for the crawl to complete
Check the source status in your dashboard — it should show "Ready"

Widget covers an important element on mobile:

The chat bubble position can be adjusted in Bots → Customize in the Factfu dashboard

Performance impact

The widget script is ~30 KB gzipped and loads asynchronously with defer. It won't slow down your Wix site or affect your SEO scores. The script loads after your page content, so visitors see your site first.

Factfu has a generous free tier:

	Free	Starter ($19/mo)	Pro ($49/mo)

Wrapping up

Adding a chatbot to Wix takes about three minutes — most of which is waiting for Wix to load its editor (we've all been there).

Paste one script tag, publish your site, and your visitors get instant answers to their questions. Your Wix site goes from a digital brochure to an actual conversation — and that's usually the difference between a visitor and a customer.
