You are not looking at this from user perspective. It's very much a paper based flow for them. Where it wins is that it lets people forget about digital devices while creating their content while letting them choosing to share some of it online post that. There are magic notebooks, magic pens etc that use ocr to achieve the same but you still need to do the creation using those devices (which are at least twice the $99 price).

Because you are a developer, you are thinking in gpt/ocr/website building etc. Lot of people especially older generations eager to share stuff will find this useful if not amusing. For them its write something on paper and get a link back. Real users don't care about WordPress plugins.
