About Affinity Photo

so, this one day, i saw, a video on youtube that show the most interesting part of AP that i’ve ever seen, its the Draw persona, and Pixel Persona, basically you get to work with the Pixel space and vector space at the same time, and that is absolutely interesting to me.

i wonder if this is only AP exclusive only? or can i do it in another software? (without bouncing back and forth betweem, say, ai and ps)
