What ai atc

what’s a good ai atc that’s either free or provides a demo

No, is basically the answer, sayintention.ai do offer demo…caveat only vfr for USA only…I am UK based and tbh I have prescribed, It is fabulous despite my reservations.

I tried it and loved it…its not cheap. I am not a one-trick pony, I like to fly everywhere and anywhere GA and airliners.
Default ATC never worked for me, it always assumes I only fly USA.
I have all ai atc
Pilot2atc
PF3
FSHUD
Pro-Atc-SR

All have their issues and caveat
Just waiting for BATC to be released…wait and see with excitement.

Think PF3 offer a try before buy.
