Well, web startups don't work that way.

The workflow is:

    listens for news-highlighting requests

    gets each and every webpage/feed

    detects the main content

    processes the content and pinpoints the relevant sentences from each news article

    creates a new enhanced webpage/feed containing the color-highlighted relevant bits

    sends the results to your browser (webpages) or gives them to your RSS Reader

The hard-lifting is done by a semantic component built in-house.
