Hi @Zoxsis,

You can change the font size by overriding it in your custom CSS using the .ygpt-chatbot class. Just add:

.ygpt-chatbot.ygpt-chatbot {
  font-size: 16px; /* or any size you prefer */
}

Here is the documentation that you can follow for further customisation: https://docs.yourgpt.ai/chatbot/customization/sdk/styling

Thanks. That didn't change the message font size not at least in the separate bot widget page (https://widget.yourgpt.ai/1db2c14b-2363-439c-93c0-4f6c3779acab)

Let me share this with our development team and get back to you shortly.
