Wolfram Alpha: Making the world’s knowledge computable

"Wolfram|Alpha is more than a search engine. It gives you access to the world's facts and data and calculates answers across a range of topics, including science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music, and much more."

Wolfram|Alpha introduces a fundamentally new way to get knowledge and answers — not by searching the web, but by doing dynamic computations based on a vast collection of built-in data, algorithms, and methods.

Is Wolfram|Alpha a search engine?

No. It's a computational knowledge engine: it generates output by doing computations from its own internal knowledge base, instead of searching the web and returning links.

Is Wolfram|Alpha free to use?

Yes, it's free for personal noncommercial use as described in its Terms of Use. Access to enhanced features and ad-free site use is available through a subscription to Wolfram|Alpha Pro.

Who is Wolfram|Alpha for?

Everyone! Its goal is to bring expert-level knowledge to everybody.

Where can I see a demo of Wolfram|Alpha?

Watch Stephen Wolfram's screencast, browse the Examples, or take a tour of Wolfram|Alpha.

How can I find the latest information about Wolfram|Alpha?

Follow us on both Twitter and Facebook, or check out the Wolfram|Alpha Blog for the latest developments.

How often is Wolfram|Alpha updated?

Wolfram|Alpha's data is continually being updated, often in real time. Its code base is always being developed, and new versions are rolled out frequently. You can apply to test new versions before they are publicly available.

When will Wolfram|Alpha be finished?

Never. There'll always be knowledge to be added and updated, and new capabilities to be introduced. The Wolfram Mathematica system (on which Wolfram|Alpha is built) has been in continual development since 1988.
