Why do I have to buy it separately?

Hello Mahin, thank you for your feedback!

While we continue to add features to Elementor Pro with each update, we also want to expand our range of services with Elementor Apps such as AI and the Image Optimizer.

We offer free trials for all of them so our users can see if they are the right fit for their website, but at the end of the day, they are separate tools from our Elementor Pro plugin and as such they have a separate cost.
