* enter any two stocks
IBM Apple
* enter any calculation
$250 + 15%
* enter any math formula
x^2 sin(x)
Wolfram|Alpha’s long-term goal is to make all systematic knowledge immediately computable and accessible to everyone. They 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.
Wolfram|Alpha aims to bring expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. Their goal is to accept completely free-form input, and to serve as a knowledge engine that generates powerful results and presents them with maximum clarity.
Wolfram|Alpha is an ambitious, long-term intellectual endeavor that they plan will deliver increasing capabilities over the years and decades to come. With a world-class team and participation from top outside experts in countless fields, their goal is to create something that will stand as a major milestone of 21st century intellectual achievement.
