Wolfram Alpha (also written WolframAlpha and Wolfram|Alpha) is an answer-engine developed by Wolfram Research

Wolfram|Alpha is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer as a search engine might. It was announced in March 2009 by British scientist Stephen Wolfram, and was released to the public on May 15, 2009.
