The world's first AI question-answering platform.
We are using our unique semantic technology to build the first internet-scale platform for directly answering the world's questions. As knowledge is added to the platform we understand and answer more and more.
The True Knowledge session at the Semantic Technologies Conference 2010 was where I first heard of this and tried to use their web-based interface during their presentation and was very impressed by the interface. It includes a justification trace of how answers are reached and handles things such as temporal reasoning as well. Also includes a Google chrome extension to enhance google answers with results to the same questions.
