A bit bland for a start,...but I've seen far worse. I consider it a good start for an isekai story. She is OP and ... we'll see how this goes.
I like how the author interweaved her sensations into her analyzing her situation. Nothing I didn't already read, but embedded in smoothest way I've seen so far. It is clever and makes the MC look clever. This is a hint at some serious writing skillz. The setup makes sense. Only her being an all beloved, all good ojou-sama with dead parents, a serious disability and a rich, genius grandfather, who happened to develop a working A.I....that's a bit thick. You could create three superhero-BG-storyies or make 1.7 religions out of this. The threat of a Mary Sue is strong with her.
