"Working on Kards, we haven’t just created a new productivity app. We’ve created a set of new technologies to support the creation of productivity apps." - this and the natural language processing sounds interesting. I'm using a mix of a task manager and Evernote which is definitely not the perfect setup.
it's not my app, but I'm in their beta. With Kards you can enter things you want to remember (bookmarks, recipies, quotes, movies, books etc.) in a really simple and smart way (natural language processing). The software itself takes care of organizing these items and makes it really easy to find them again. Right now they try to find as many use cases as possible.
