Interior Designers certainly have taste and the best ones take time (and charge a lot of money). But for those who can't afford them, now there's AI. You can take an image of a room and transform it 10 ways from Sunday, in minutes. These images are some examples of such effort. Single image to start with and then a number of variations. Obviously some look better than others, I even included one using PCS Fx' Coloring Book effect, in case you're not satisfied with the colors there and want to do your own. All of these were created with PCS Fx and you should really look at them fully open to appreciate them fully. The thumbnail images don't do them justice.
Would you use AI to redecorate your home? Based on this little experiment of mine, I'm pretty certain I would.
