DeepType - Surface relevant information as you type

Early when I first started writing nearly 15 years ago, I realized just how difficult it was to write about topics that I didn't know about. With DeepType, a dream has been brought into reality. Now, anyone can type with a database by their side, powering their writing with knowledge and inspiration. I have spent many hours working on DeepType to provide a lightweight but powerful experience. All of the code is freely available on my GitHub. I will be around to support anyone who wants to try DeepType, to assure that your documents are treated with the respect they deserve! Any and all feedback is encouraged, as DeepType still has much room to grow. Thank you for your time!

I would suggest adding some sort of voice over to the video, because I don't really understand how the product works. It must be super obvious to you because you made it, but consider it might not be as obvious to people unfamiliar with it.
