Would you use it if you could use AI to generate mind maps with one click?
xmind.app
xmind.app
That said, it really depends a bit on what the mindmap is for. Their website lists several examples including what seems to be more technical documentation. For that sort of thing it'd probably be quite good.
OpenAI only for now, I'm afraid.

For instance, it might be interesting to do free association type thinking alongside an ai with a mind-map like visualization of the ideas and concepts we treat.
For instance, a concrete example, use the ai to suggest different intermediate nodes to link two existing nodes. Like, "Ways to get from [vehicle] to [food]"
