I was looking a solution for the same spiral text effect.

I use this online tool to make text on spiral path but unfortunately the size of the text is the same, not ascending or descending gradually ?

You could try Motion Blur, Gaussian Blur and Warp

You can use the Refine Edge to smooth the edges. Or you can use this smooth edge Photoshop action https://www.photoshopsupply.com/actions/smooth-edges-photoshop-action-free
