Book Bolt Studio has an option to allow you to create multiple different covers that may look similar but use different words!
In order to do this, first open up your cover file, and select the text menu on the left hand side:
From here, select text with variants:
Once the text variant is added to the screen, you will want to click on edit text variants in the top menu:
What this will allow you to do, is edit the different types of text that you want on the screen.
Enter in 1 per line:
In this case, we have it set to dog, cat, sheep, and cow.
This means that when we download this project, it will download 4 covers, and each cover will say a different word on it!
This is incredibly useful when scaling up your cover game on KDP!
