Maybe a better submission would've been the homepage itself, which has the app's purpose in a single lead graf:

https://getpolarized.io/

> A powerful document manager for Mac, Windows, and Linux for managing web content, books, and notes - supports tagging, annotation, highlighting and keeps track of your reading progress.

I suppose the author's assumption is that a normal user/visitor to the site would have seen the homepage before seeing the crowdfund pitch.
