WolframAlpha (/ˈwʊlf.rəm-/ WUULf-rəm-) is an answer engine developed by Wolfram Research.[3] It is offered as an online service that answers factual queries by computing answers from externally sourced data.[4][5]

WolframAlpha was released on May 18, 2009, and is based on Wolfram's earlier product Wolfram Mathematica, a technical computing platform.[1] WolframAlpha gathers data from 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,[3] CrunchBase,[6] Best Buy,[7] and the FAA to answer queries.[8] A Spanish language version was launched in 2022.[9]



Users submit queries and computation requests via a text field. WolframAlpha then computes answers and relevant visualizations from a knowledge base of curated, structured data that come from other sites and books. It can respond to particularly phrased natural language fact-based questions. It displays its "Input interpretation" of such a question, using standardized phrases. It can also parse mathematical symbolism and respond with numerical and statistical results.[citation needed]


WolframAlpha is written in the Wolfram Language, a general[clarification needed] multi-paradigm programming language, and implemented in Mathematica. Wolfram language is proprietary and is not commonly used by developers.[10]


WolframAlpha was used to power some searches in the Microsoft Bing and DuckDuckGo search engines but is no longer used to provide search results.[11][12] For factual question answering, WolframAlpha was used[when?] by Apple's Siri and Amazon Alexa for math and science queries but is no longer operational within those services.[13][14] WolframAlpha data types[clarification needed] became available in July 2020 within Microsoft Excel, but the Microsoft-Wolfram partnership ended nearly two years later, in 2022, in favor of Microsoft Power Query data types.[15] WolframAlpha functionality in Microsoft Excel ended in June 2023.[16][17]


Launch preparations for WolframAlpha began on May 15, 2009, at 7 p.m. CDT and were broadcast live on Justin.tv. The plan was to publicly launch the service a few hours later. However, there were issues due to extreme load. The service officially launched on May 18, 2009,[18] receiving mixed reviews.[19][20] In 2009, WolframAlpha advocates pointed to its potential[vague], some stating that how it determines results is more important than current usefulness.[19] WolframAlpha was free at launch, but later Wolfram Research attempted to monetize the service by launching an iOS application with a cost of $50, while the website itself was free.[21] That plan was abandoned after criticism.[21]

On February 8, 2012, WolframAlpha Pro was released,[22] offering users additional features for a monthly subscription fee.[22][23]

Some high-school and college students use WolframAlpha to cheat on math homework, though Wolfram Research says the service helps students understand math with its problem-solving capabilities.[24]

Copyright claims[edit]

InfoWorld published an article warning readers of the potential implications of giving an automated website proprietary rights to the data it generates.[25] Free software advocate Richard Stallman also opposes recognizing the site as a copyright holder and suspects that Wolfram Research would not be able to make this case under existing copyright law.[26]
