The plan was to publicly launch the service a few hours later. Launch preparations began on May 15, 2009, at 7 p.m. WolframAlpha functionality in Microsoft Excel is deprecated in June 2023. WolframAlpha data types were available beginning in July 2020 using Microsoft Excel, but that partnership ended in favor of Microsoft Power Query data types.

For factual question answering, it was previously queried by Apple's Siri and Amazon Alexa for math and science queries but is no longer operational within those services. WolframAlpha has been used to power some searches in the Microsoft Bing and DuckDuckGo search engines but is not currently used. WolframAlpha is written in the Wolfram Language, a general multi-paradigm programming language, and implemented in Mathematica and ran on more than 10,000 CPUs as of 2009. Mathematical symbolism can be parsed by the engine, which responds with numerical and statistical results. It displays its "Input interpretation" of such a question, using standardized phrases. It is able to respond to particularly phrased natural language fact-based questions, or more complex questions. WolframAlpha then computes answers and relevant visualizations from a knowledge base of curated, structured data that come from other sites and books. Users submit queries and computation requests via a text field.

Additional data is gathered from both academic and commercial websites such as the CIA's The World Factbook, the United States Geological Survey, a Cornell University Library publication called All About Birds, Chambers Biographical Dictionary, Dow Jones, the Catalogue of Life, CrunchBase, Best Buy, and the FAA. WolframAlpha was released on May 18, 2009, and is based on Wolfram's earlier product Wolfram Mathematica, a computational platform for calculation, visualization, and statistics capabilities. It answers factual queries directly by computing the answer from externally sourced data. r əm-/ WUULf-rəm-) is a computational knowledge engine and answer engine developed by Wolfram Research.
