Here are a few of the most interesting Wolfram Alpha statistics and facts I was able to dig up including user counts. As always, be sure to check back in the future as I will be updating this post as new and updated stats become available.
What is Wolfram Alpha?
Wolfram|Alpha’s long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. We aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries.
