Topaz tutorial

I just updated Topaz AI. Are there any tutorials for using this. I got to say that I have had Topaz for quite some time and I am just not seeing that topaz is doing much at all in my picture quality. I also have the stand alone Denoise and I got to say that love this but when I bring pictures into AI I am not seeing the same quality in getting rid of the noise as I am with the stand alone denoise. Why is that. With Denoise I am saving 100% of my photos but I am not saving anything that comes out of AI. After saving a picture from AI that I applied denoise, I had to send this through the stand alone denoise program again. I don’t understand.
