I have made a custom GPT, which I am using to create articles for our company, with full html-coding applied. Which we used to create articles in Zendesk. This week we moved to Intercom. I was under the impression that most tools, from this time of day (2025), support html-coding and html-desgining.

But now that we have moved to Intercom, what I read online, it is impossible to change the html of the articles within the designer. Which is key for quickly creating and changing articles. Also, Intercom provides very little support for HTML and CSS coding in general. Because of this, we seem to be unable to add (styled) blockquotes with custom colors and lines (appearance). See below.

For example, this block underneath to highlight something important

For example, the FAQ underneath to show additional questions, which can be unfolded by clicking on them.

Main concern

If it is possible to create the above or something very similar that would be nice. But this does still not help me out, because we need to be able to create a ‘draft’ article by using our custom GPT, which we only need to copy and paste with one click so that it fits our html-coding for articles (including the formatting from these blocks above) into the article builder. I do not want to make all these changes manually, because it will take us a lot of unnecessary time. Which would be a big fallback in automating our processes, as we have invested a lot of work in lately.

Can somebody help me out here, or is there anything in the pipeline which would make html-editing much more easy and complete? 

Also, if anyone has another idea for an external platform to use which (the articles) integrates seamlessly with Intercom and Fin, then that would be much appreciated also.

Thanks!
