The split view allows you to move a slider across the image to see a before (left) and after sharpening view (right).

The attached pictures give an impression what Topaz Sharpen AI can do. It includes only two settings sliders: one for sharpness (remove blur) and one for noise suppression. Sharpen AI works by targeting and reversing three specific types of blur to create more “natural” results: "motion blur" (stabilize), "out of focus" and "softness". Topaz claims to use Artificial Intelligence (machine learning), which can tell the difference between real image information and image noise. Topaz Sharpen AI is a sharpening and shake reduction photo retouching software, which can help make blurry or out-of-focus areas of images sharper. Recently, I started using another software product from Topaz – Sharpen AI - for sharpening my (astro) pictures.

Topaz Denoise AI seems to be frequently used for noise reduction in astrophotography.
