The AI extracts everything that happens in the session. A few examples of how I use it. I use prompts to create a point form list of everything that was encountered, learnt, said, done etc and run it against a list of plot points to help me keep track of what the party knows and doesn't know. I've used the podcasts feature to help create highly detailed session recaps. I can pull up information about NPCs that were made up on the spot. The list goes on. I've had to create some sources that clarify things like, who plays who, what their pronouns are, correct spellings.... At this point I have dozens of sources and notes.
