I purchased Nodeland solely because of the AI mind mapping feature, and I really like it too! I enter a book title (e.g. "Adventures of Tom Sawyer"), and 15 seconds later, a nicely defined mind map is generated, with graphic icons at the end of each node. How sweet! You also have the option of exporting the mind map as a JPG, PNG, or JSON file. I'm still trying out the other features, and I'm sure they'll be just as good as easy to work on.
UI-wise, I wish the export option was easier to find. Right now, it's tucked away in the hamburger (3-line) button...This could be made more visible, IMHO.
Anyway, for the price, it's hard to go wrong on this deal, especially if you're a graphic-oriented person like me. Recommended.
