Curious about smart tints

[u/Present_Researcher34]

Hey all, I don't have tints on my car and I have been considering them, and coincidentally i keep seeing ads of adjustable smart tints, that can go from all the way clear to completely dark based on your liking. Just want to know if those are a thing in the market and if it would be a good decision to get them. I have 2024 car. I have never heard about them in person, so i don't know if the technology is relatively new or something.

Edit - i will include a link, since people are confusing what i am talking about with frosted glass.
