I am a 2 on the Aphantasia scale, so I can't create photo realistic images in my head, but I can envision detailed enough phenomena in order to build a Memory Palace from time to time, I am out of practice now. I really only started learning history long after I stopped using such technique, not that I ever really used them extensively anyway. I found a better way to remember things was just to find them actually interesting, on some level or for some purpose. When it comes to history I find I structure things in terms of interweaving narratives. Events A and B happen begetting event C, and so on. Since I have found a way to find such events interesting my brain just keeps track of how one feeds into another, no scaffolding required.
I dont know if any of that helps, but I hope so
The reviews on CryAnalyzer at least are pretty bad. I think we may still have a long way to go
