After creating your chatbot, proceed to the chatbot dashboard. Navigate to "AI Knowledge" to add your data to chatbot.

Add knowledge base to GPT chatbot

There are various data sources supported like Text, File, and Website. For this tutorial, we'll use Website as the data source. Enter the URL (starts with https://) from which you want the system to extract data. Click Crawl to initiate the process. For example, we will use as the website URL.

  • Note: The crawling process typically takes 30 seconds to 5 minutes, depending on the size of the website.

Once the crawling is complete, you'll see a list of URLs. Check the boxes next to the URLs you want to use for training. You can select all by clicking the checkbox at the top. Click Update Knowledge to proceed.

If the crawler doesn't detect any URLs, choose Advanced under the Crawl button and check Javascript Rendering.

Your chatbot will now be training. The duration varies, taking approximately 5 seconds for small datasets and up to 15-20 minutes for very large datasets.

Step 4: Share or embed the chatbot on website

Now that your ChatGPT chatbot is ready, it's time to make it accessible on your website. Head to the Integrations section in the sidebar of your dashboard. Toggle the switch to Allow Public Access:

Add ChatGPT chatbot to your website
  • Share: Use the url provided in this section to access chatbot directly
  • Add to website:
    • To display a chat bubble at the bottom of the screen: Add the first script (<script src=""...) to the <body> or <footer> of your website.
    • If you prefer placing the chat window at a specific location, use the provided iframe code (<iframe...)

And there you have it! Creating and integrating a ChatGPT chatbot into your website has never been simpler.
