Text to MindMap - an augmented experience

Hi,
This is my first post on Indiehackers.

I often mind-maps to organise my thoughts. I find them a natural structure to put thoughts as it intuitively feels it's similar to how brain works (one thought originating from another) . I currently use mindly on ipad to make these maps.

One thing I would love is to create mind-maps while typing in text. That is, generate mindmap without taking hands off the keyboard. This is because the act of creating new nodes and dragging it around feels like a break of flow while I'm in the thought generating process.

I'm envisioning a framework which would seamlessly let you create mind-maps while you type. This would involve an easy syntax and augmented tool that would help you.

There are majorly two things to it:

1. Determine when a new node starts. I think of something similar to the '/' feature used in notion. Everytime you type '/' , it let's the tool know it's a new node.
2. Determine where to place that node in the tree. This can be done by color-coding or letter-coding the existing nodes and prompting the user to select one on the go.

I'm a data-scientist and have little experience in product building. I'm looking for validation of this idea, and any thoughts on how to go about building it. Especially the stack that would best fit the process.

Thanks for reading!
