I really loved the demo, the various game mechanic are pretty fun, and the character personalities was my favorite part.
Having said that, the AI text is very obvious and puts me off from reading the dialogues despite how much I enjoyed the characters and their banter. For once I can take the AI in her head talking like that as a meta joke, but constantly having to read AI text gets jarring. I'd suggest just cutting down on a lot of unnecessary "filler" dialogue that AI loves to do, or edit it to sound natural.
Similar issue with the tiny character images with the dialogues. It's better to have only one good looking image to represent the character and later down the line hire an artist to draw the different expressions.
