Intelligent Embeddable Web Components

I've been toying with and inventing some cutting edge web technology that would enable me to embed and control sophisticated and functional apps in web pages. For example I can build an entire interactive app that handles user reviews and embed that on any web page. I can hook up a back end to the app so that I can store and read data, get push updates, and control usage of the app on any web page that embeds that app.

Versions of this exist in the form of HTML and JS that others write but these are generally pretty primitive and hard to implement. The improvement is the ability to write an entire independent app that both me and the implementer can control. I can allow the implementer to manipulate what a user sees in the app on the page and also give them access to any data that it creates via a back end. I can use features like sophisticated animation, video embedding, speech to text, and interactivity to the app.

I would be able to distribute my app to anyone building a web page and potentially charge a subscription to use my app on the implementer's page. This is similar to Wordpress plugins but offers much more capability. This is essentially a "better mousetrap" approach but provided I choose a weak target to beat and implement something an order of magnitude better I think I could be successful with it.

I'm curious to get feedback on this approach to reach users and make money. It relies on me identifying an initial use case that can be improved by the technology and following through to make something compelling. I'm also curious to see if anyone has any thoughts about what they might do with the technology?
