Database with information you can refer to when making an article
In other tools it is often called "Snippet(s)".
How it works is as follows:
You can create a text file with information (for example about a company, like the services they provide etc.)
Then when making a new blog article you can select wich "Snippet(s)" you want to pull data from.
And now you can make a prompt like: Create a blogpost that explains the services of Company AB.
This would create awesome personalized content.
