Who knows the software for synchronous text replacement on the site and in SharePoint (or equivalent)?

Question

SharePoint

People, hello!
There is a question, the answer to which has not yet been found, I ask you :).
The bottom line is this:
You need to find some kind of software solution to link content on the site and content in SharePoint.
It is possible some analog of SharePoint - it is not important.
For example, I change the keyword in the text on the site (or any other word) - and it changes in the link in SharePoint (or in its analogue).
Or I change the article in SharePoint (or change the copywriter), and all these changes are applied on my site.
Maybe somehow this can be implemented through a search, for example, I change the word "site" to SharePoint and on my site this query is searched for mentions of this word. And then I change it manually.
Some terms sometimes change and sometimes catching everything and replacing it turns into a global problem. I would like to somehow automate and optimize the process itself.
There are ideas that it should be something similar to 1C or some kind of database, but apart from ideas, nothing else comes to mind.
If someone knows such software or at least something similar - then thanks in advance.
