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.

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

We certainly hope so. We spend considerable effort on automated testing, expert review, and checking external data that we use. If you ever see a problem, please report it.
Can I assume that my inputs to Wolfram|Alpha are private?
Can I contribute to Wolfram|Alpha's knowledge base?
How can I get involved with Wolfram|Alpha?
How should the name Wolfram|Alpha be written?
In a two-color rendering, just give each of the two words different colors, with no space in between. In a one-color rendering, separate the words with a vertical bar ( | ).
What are the parts of Wolfram|Alpha's output called?
Each labeled section is called a pod. Pods can have subpods. Clickable elements like "More" are called buttons. Disambiguation questions at the top are called assumptions.
