How to Add an AI Chatbot to a Notion Site

Yes, you can add a chatbot to a Notion site — even though Notion doesn't want you to. Here's how to make your published Notion pages interactive with an AI assistant.

Notion is great for many things. Custom code isn't one of them.

Notion Sites let you publish pages to the web with a custom domain. Clean. Minimal. Very Notion. Visitors can read your beautifully organized page — and that's pretty much it.

No custom JavaScript. No script injection. No widget embeds. Notion's philosophy is "we handle the rendering, you handle the content." Which is elegant until a visitor wants to ask a question about that content and the only option is... scrolling more?

The good news: there's a workaround. The better news: it takes about 6 minutes.

The honest truth about Notion + chatbots

Notion Sites doesn't support custom script injection natively. There's no "custom code" field in site settings. So you can't just paste a <script> tag and call it a day.

But you can embed external pages using Notion's /embed block. And you can use a Super.so, Potion.so, or Notion-to-website service that wraps your Notion content and does support custom code injection.

Here are your options:

Option A: Using Super.so or Potion.so (recommended)

If you're already using a Notion-to-website tool like Super.so, Potion.so, or Hostnotion, you're in luck — all of them support custom code injection.

Super.so

  1. In your Super.so dashboard, go to Site Settings → Code
  2. In the Custom Footer code section, paste:
<script
  src="https://factfu.com/v0/widget.loader.js"
  data-widget-key="pk_your_key_here"
  defer>
</script>
  1. Save and publish

Potion.so

  1. Go to Site Settings → Custom Code
  2. Paste the same script in the Footer section
  3. Deploy

That's it. The chatbot appears on your Notion-powered site, floating in the corner, ready to answer questions about your lovingly structured content.

Option B: Native Notion Sites (workaround)

If you're using Notion's built-in Sites feature without a wrapper tool, you can link visitors to the chatbot rather than embedding it directly:

  1. Create your Factfu chatbot (factfu.com/signup)
  2. Add your content (crawl your Notion site URL, paste FAQs, upload docs)
  3. In the Factfu dashboard, go to Settings → Widget
  4. Copy the direct chat link (looks like https://factfu.com/chat/pk_your_key_here)
  5. In your Notion page, add a callout block or button that links to this URL

It opens the chat in a new tab. Not as seamless as an embedded widget, but it works — and it's better than a contact form that nobody checks on weekends.

Option C: Embedded iframe (creative workaround)

If you want something more integrated on native Notion Sites:

  1. Create a simple HTML page that loads the Factfu widget:
<!DOCTYPE html>
<html>
<body style="margin:0; background:transparent;">
  <script
    src="https://factfu.com/v0/widget.loader.js"
    data-widget-key="pk_your_key_here">
  </script>
</body>
</html>
  1. Host that HTML file somewhere (GitHub Pages, Netlify, Vercel — all free)
  2. In Notion, type /embed and paste the URL to your hosted HTML page

The widget will render inside the embed block. It's not as polished as a native floating widget, but it gets the job done.

Setting up the chatbot (all options)

Regardless of which embedding method you choose, the bot setup is the same:

  1. Go to factfu.com/signup — free, 200 messages/month
  2. Create Bot and name it
  3. Add content:
    • Enter your Notion site's published URL → the bot crawls your pages
    • Paste any additional FAQ text
    • Upload reference documents
  4. Go to Settings → Widget to get your widget key and embed code

Should you even use Notion as a website?

Look, we're not here to judge your CMS choices. Notion is great for internal docs and simple public pages. If it works for you, it works. But if you're finding yourself fighting against limitations like "I can't add a script tag" — it might be time to consider a tool that's actually designed to be a website.

In the meantime, the workarounds above will get you a working chatbot on your Notion-powered site. Your visitors get answers, you get fewer repetitive emails, and Notion continues being Notion.

Create your free Factfu account and let your Notion content do more than just sit there looking organized.
