## Using Wolfram|Alpha

### How can I get started with Wolfram|Alpha?

Browse the Examples by Topic page, take the tour or just type something you want to compute or know about into the input field at the top of the page.

### What can I do with Wolfram|Alpha?

Many, many things. Check out the Examples by Topic page and the Visual Gallery of Examples for a few pointers. Or visit the Wolfram Blog or Wolfram Community to see what others are doing.

### Why doesn't Wolfram|Alpha understand what I asked?

You might need to ask it differently, or it might be that Wolfram|Alpha doesn't yet cover what you're asking about. Try making your query the minimum number of words needed to communicate. Try different words or notations. And be sure to check your spelling. If you still need help, Pro Premium users can try contacting Pro Premium Expert Support.

### How can I get help with Wolfram|Alpha?

Join the Wolfram|Alpha group on Wolfram Community, visit the Wolfram|Alpha Facebook page or contact us.

### How do I report a bug or give feedback about Wolfram|Alpha?

Just use the feedback form on the bottom of every results page. You can also have discussions on the Wolfram|Alpha group on Wolfram Community.

### Is there a manual for Wolfram|Alpha?

Wolfram|Alpha works by taking free-form linguistic input, so there's no need for a manual as such. Check out the Examples by Topic page to get a sense of what Wolfram|Alpha can do.

### How can I optimize my queries to Wolfram|Alpha?

Use as few words as possible to communicate. Use unambiguous whole words. Just describe what you're interested in; you don't need to explicitly ask a question. For more guidance, take a look at the Examples By Topic page. If you still need help, Pro Premium users can try contacting Pro Premium Expert Support.

### How does Wolfram|Alpha deal with linguistic ambiguity?

It ranks possible interpretations, gives results for the one it thinks is most plausible and gives links to click to get other ones. It often uses your location to rank interpretations—say, favoring cities that are near you.

### When Wolfram|Alpha prompts for input, what can I enter?

Pretty much anything you could put into the main Wolfram|Alpha input field. For instance, if you're asked for a density, you can either give an explicit number or a response like "water".

### Will I always get the same answer to a particular question?

Usually, but not necessarily. Some results may depend on the time and/or location of the query. In addition, Wolfram|Alpha is continually being updated and enhanced.

### How does Wolfram|Alpha know where I am located?

It uses GeoIP, tracing back from the IP address it picks up when your browser contacts the Wolfram|Alpha server. The location it deduces should be correct to within about five miles. You can also set a specific location in the "Preferences" tab of the user drop-down menu in the top-right corner of Wolfram|Alpha pages.

### Why does Wolfram|Alpha use the wrong location for me?

Wolfram|Alpha deduces your location from your IP address. If you are using a VPN, satellite internet or some other complex form of network, you may have to correct your location explicitly by including it in your input or by setting a specific location in the "Preferences" tab of the user drop-down menu in the top-right corner of Wolfram|Alpha pages.

### How can I tell Wolfram|Alpha my location?

Wolfram|Alpha should automatically know your approximate location from GeoIP. If for some reason it does not, you can include a city or latitude, longitude specification in your input.

### Does Wolfram|Alpha handle languages other than English?

Yes, we have a Japanese version available at ja.wolframalpha.com, and additional languages are planned.

### Can I interact with Wolfram|Alpha graphics?

With a Wolfram|Alpha Pro subscription and the free Wolfram CDF Player plugin, you can get dynamic versions of existing Wolfram|Alpha output with interactive controls, 3D rotation, animation and much more.

### Can I get data from Wolfram|Alpha in spreadsheet format?

Wolfram|Alpha Pro's data download supports many formats, including CSV, XLS and more. For a list of supported download formats, see the Data Download Samples page.

## Web & Other Practicalities

- Sign in to Wolfram|Alpha. If you do not yet have a Wolfram ID, you'll need to create one.
- Click the drop-down arrow next to your Wolfram ID (top right).
- Click Preferences.
- Configure your options under the various tabs.

If you're unable to sign in, you may be able to use your browser's magnification tools to adjust your view of Wolfram|Alpha.

### How can I copy results out of Wolfram|Alpha?

Hover over any result pod or click the gear icon and a small toolbar will appear in the bottom-left corner. Click the icon for a plain text version of that result pod. Select and copy the text as you would any other text on the web.

### Can I bookmark Wolfram|Alpha results?

The URLs of Wolfram|Alpha results can be bookmarked. Wolfram|Alpha is not a directory; it computes answers on the fly. Results will be recomputed using your current time and location when visiting a bookmarked Wolfram|Alpha result URL.

### Are there toolbars, widgets and so on available for Wolfram|Alpha?

Yes. See the Resources & Tools page.

### Can I use non-English characters in Wolfram|Alpha input?

Yes. If your browser can handle a special character, Wolfram|Alpha will be able to as well. However, Wolfram|Alpha currently only understands questions in English or Japanese on ja.wolframalpha.com.

You also have access to an onscreen extended keyboard, allowing you to input additional symbols to give your formulas correct technical formatting. The keyboard includes all common Greek characters and a curated collection of other special characters.

### What does Wolfram|Alpha know about me?

Wolfram|Alpha knows only what your browser transmits to the web server—primarily your IP address, from which Wolfram|Alpha deduces your approximate geographic location. (Note that this information is protected by our Privacy Policy.)

### How can I compute with results from Wolfram|Alpha?

There are a few options. Depending on the result, the "Copyable plaintext" dialog may contain pre-formatted code you can use directly in any Wolfram Language interface. The WolframAlpha function in Wolfram Language 9+ enables direct Wolfram|Alpha free-form input in your notebook environment. You can also use the "Open code" feature to interact with results in the Wolfram Cloud. Finally, Wolfram|Alpha Pro subscribers can download results pages in the Computable Document Format (CDF).

### Why can't I hear a sound that Wolfram|Alpha has generated?

Wolfram|Alpha generates sounds in MIDI format, which may require a plugin for certain browser configurations.

## Scope of Wolfram|Alpha

### What can I ask Wolfram|Alpha?

Eventually you should be able to ask it about essentially any kind of systematic factual knowledge. You can get an idea of what it covers today by looking at the Examples. You can track its progress through the Wolfram Blog and the Wolfram Community.

### How can I tell whether Wolfram|Alpha covers a particular area?

The easiest thing to do is just to try a simple case of it. You can also browse the Examples by Topic page, or ask on Wolfram Community.

### What are Wolfram|Alpha's main limitations?

It can only know things that are known, and are somehow public. It only deals with facts, not opinions. It limits the computation time for each query. And, of course, it's in continual development—and always will be.

### In what areas is Wolfram|Alpha strongest?

We've first emphasized areas where computation or mathematics have traditionally had a more significant role, or where knowledge is more readily quantitative. But we're steadily working through all the content areas covered by reference libraries, handbooks and much more.

### How much math can Wolfram|Alpha do?

Pretty much anything that's possible using today's best algorithms—subject only to the constraint that the computations must complete in the time Wolfram|Alpha has available.

### Can Wolfram|Alpha do higher math?

Yes, absolutely. It has access to all of the Wolfram Language's algorithms, which cover algebra, calculus, geometry, number theory, discrete math and much more.

### Does Wolfram|Alpha cover what is in standard math handbooks?

Yes, quite thoroughly, including everything in standards like Abramowitz & Stegun, Gradshteyn & Rhyzik and many, many others. It covers much that isn't in such books, as well. And because Wolfram|Alpha performs real-time computations rather than simply looking up data, it can always derive new results.

### Does Wolfram|Alpha cover what is in handbooks of chemistry and physics?

Yes, fairly thoroughly. And it's not just able to look up tabulated values, but also to compute from empirical formulas and so on, and to use such results as inputs to other computations.

### How broad is Wolfram|Alpha's coverage of socioeconomic data?

For data that's systematically available internationally, its coverage is quite broad. There's more to do on data that's specific to particular countries.

### Does Wolfram|Alpha have real-time financial data?

Yes. Wolfram|Alpha gives the latest trade quotes in real time.

### How much data does Wolfram|Alpha have on weather?

Pretty much everything that's available, going back more than a century in some places. And it's constantly getting new real-time data.

### How much data does Wolfram|Alpha have about people?

Basic computable information about well-known people, such as birth and death dates, government positions, major awards, etc. More data and connections are being added.

### How much data does Wolfram|Alpha have on popular culture?

Basics, particularly about more computable issues, such as movie box-office grosses. More is being added.

### Why doesn't Wolfram|Alpha have data on a particular domain?

Most likely because we haven't gotten to it yet. Feel free to contact us with contributions or suggestions of data that we should include.

## Data in Wolfram|Alpha

### How much data is there in Wolfram|Alpha?

Many trillions of elements, continually growing through a large number of feeds.

### Does Wolfram|Alpha get its data from the web?

No. It comes from Wolfram|Alpha's internal knowledgebase. Some of the data in that knowledgebase is derived from official public or private websites, but most of it is from more systematic primary sources.

### Where does Wolfram|Alpha's data come from?

Many different sources, combined and curated by the Wolfram|Alpha team. At the bottom of each relevant results page there's a "Sources" button, which provides background sources and references.

### Can I find the origin of a particular piece of data?

Most of the data in Wolfram|Alpha is derived by computations, often based on multiple sources. A list of background sources and references is available via the "Sources" button at the bottom of relevant Wolfram|Alpha results pages.

### How is Wolfram|Alpha's data checked?

We use a portfolio of automated and manual methods, including statistics, visualization, source cross-checking and expert review. With trillions of pieces of data, it's inevitable that there are still errors out there.

### How often is the data in Wolfram|Alpha updated?

Many kinds of data—such as financial or weather—stream in all the time. Other kinds of data are updated when they become available, on a daily, weekly, monthly or yearly basis.

### What should I do if I find an error in Wolfram|Alpha's data?

Tell us! We're always working hard to perfect the quality of our data.

### How may I use data from Wolfram|Alpha?

You can use individual pieces of data however you want. There are, however, restrictions on aggregate uses, as described in the Terms of Use. Please contact us if you're wondering about a particular use.

### Does Wolfram|Alpha stand behind the data it uses?

Yes. Although we must rely on external sources for many kinds of raw data, we curate all data and our goal is to make sure that it is perfect.

### How is real-time data curated?

Wolfram|Alpha effectively checks real-time data (such as weather, earthquakes, market prices, etc.) against built-in criteria and models. If an unexpected deviation is found, Wolfram|Alpha will normally indicate it, for example by showing lines as dashed.

### How much of Wolfram|Alpha's data comes from Wikipedia?

Most of the data comes directly from primary sources. However, Wikipedia contains excellent "folk information" about everyday practices in many domains, about the popularity and names of things (such as "the big apple" for NYC, and so on). Wolfram|Alpha uses such information especially for linguistic disambiguation.

## Education & Research

### What educational levels is Wolfram|Alpha suitable for?

Any level, from kindergarten to graduate school and beyond. On the elementary end, Wolfram|Alpha can do arithmetic showing steps, make clocks, work with colors and so on.

### Can I use Wolfram|Alpha to do my homework?

That depends on your teacher. If you do use it, don't forget to cite it as a source.

### Why does Wolfram|Alpha give a different answer from my textbook?

Check to see if your book's answer appears under "Alternate forms". It's pretty common for some forms to look different but be effectively equivalent.

### Should I cite Wolfram|Alpha when I use results from it?

Yes. For academic purposes, Wolfram|Alpha is a primary source.

### How should I cite results from Wolfram|Alpha?

The citable author is Wolfram|Alpha. Don't forget to include the time and/or place at which the query was made, as it can affect the result. You can reference results in individual pods by giving their names. See standard citation elements for Wolfram|Alpha for specific elements and an example.

### How can I find out what to cite when I use data from Wolfram|Alpha?

Wolfram|Alpha should be considered the source, just as an encyclopedia or other reference would be. If you include the Wolfram|Alpha URL in your document, your readers can go to the "Sources" button to get further references. Note that Wolfram|Alpha often combines and adapts data from multiple sources.

### Is the content of Wolfram|Alpha peer reviewed?

Yes, the content is reviewed by domain experts. It is also extensively validated using automated testing. For external data, we strive to use the most reliable sources available.

### Can I find out how specific results in Wolfram|Alpha were derived?

Elementary math results often have "Step-by-step solution" buttons, and combinations of data have "Details" buttons. "Sources" buttons give information on background sources for external data.

### Does Wolfram|Alpha contain "adult content"?

No. It has no adult images or narrative. It gives only factual answers to factual questions.

## Technology of Wolfram|Alpha

### What is the core technology of Wolfram|Alpha?

There are many parts to it, each with significant innovations. Four key general areas are the data curation pipeline, the algorithmic computation system, the linguistic processing system and the automated presentation system.

### How big is the Wolfram|Alpha source?

It's currently more than 10 million lines of symbolic Wolfram Language code, together with many terabytes of data.

### How easy is it to scale Wolfram|Alpha?

Wolfram|Alpha uses a modular server architecture, similar to many modern supercomputers. Scaling to accommodate more requests simply requires having more modules.

### Does Wolfram|Alpha use parallel computation?

Yes, extensively. In fact, outputs often have each pod computed on a different CPU.

### What kinds of computers are Wolfram|Alpha's servers?

Wolfram|Alpha uses clusters of modern x86 processors, configured in modular units.

### Can I get a private version of Wolfram|Alpha?

Running Wolfram|Alpha requires large-scale infrastructure. Custom Wolfram|Alpha solutions are available for large organizations.

### Does Wolfram|Alpha learn from user behavior?

Yes. User behavior gives excellent clues about linguistics, which we incorporate into Wolfram|Alpha.

### What is Wolfram|Alpha's internal implementation language?

The Wolfram Language. Without the Wolfram Language's high-level symbolic programming and huge base of built-in algorithms, Wolfram|Alpha simply wouldn't have been possible.

### What web technology does Wolfram|Alpha use?

Its server technology is based on Apache Web servers accessing clusters of webMathematica servers.

### Does Wolfram|Alpha use an ontology?

In effect it has a dynamic algorithmic version of an ontology, implemented using symbolic programming. A future version of the Wolfram|Alpha API may expose some of Wolfram|Alpha's internal ontology constructs.

## Context & History

### How does Wolfram|Alpha compare to search engines?

Search engines give you links to pages that exist on the web. Wolfram|Alpha computes answers to specific questions using its built-in knowledgebase and algorithms.

### How does Wolfram|Alpha compare to Wikipedia?

Wikipedia gives you pages of narrative about topics. Wolfram|Alpha computes answers to specific questions you ask, just giving facts, not narrative. Wolfram|Alpha often includes sidebar links to Wikipedia.

### What is the closest precursor to Wolfram|Alpha?

In concept, perhaps Leibniz's *characteristica universalis* from the late 1600s—or the science-fiction computers of the 1960s. Technologically, many pieces of Wolfram|Alpha have precursors, but the ambitious scope of the whole project is believed to be unique.

### Does Wolfram|Alpha use artificial intelligence?

Not in a traditional sense. Wolfram|Alpha isn't mainly based on emulating human reasoning. Instead it uses powerful methods from science and algorithmic computation to get directly to answers.

### Is Wolfram|Alpha an artificial intelligence?

It's much more an engineered artifact than a humanlike artificial intelligence. Some of what it does—especially in language understanding—may be similar to what humans do. But its primary objective is to do directed computations, not to act as a general intelligence.

### Does Wolfram|Alpha use semantic web technology?

Not directly. Wolfram|Alpha has its own internal knowledgebase, with its own extensive internal semantics and ontology.

### Does Wolfram|Alpha use natural language processing (NLP)?

Wolfram|Alpha introduces many new methods for understanding linguistic inputs. Mostly they're unlike traditional NLP, not least because Wolfram|Alpha has to deal with linguistic fragments rather than full grammatical sentences.

### Can Wolfram|Alpha discover new facts?

Whenever it does new computations, it's effectively deriving new facts. At present, it always uses established scientific or other models as the basis for its computations. But using NKS it'll probably one day be possible for Wolfram|Alpha to discover new models too.

### What is the theoretical foundation of Wolfram|Alpha?

Wolfram|Alpha attempts to synthesize all forms of knowledge that can be made computable—and uses methodology from all of them. A key general element is the concept of symbolic computation—inherited from the Wolfram Language system that underlies Wolfram|Alpha.

### How does Wolfram|Alpha relate to NKS (Wolfram's *A New Kind of Science*)?

Wolfram|Alpha makes both conceptual and practical use of the NKS idea of generating rich, complex behavior from simple underlying rules. In many ways, Wolfram|Alpha is the first "killer app" for NKS (see Stephen Wolfram's blog post).

### How does Wolfram|Alpha relate to the MathWorld website?

Wolfram|Alpha includes a large fraction of the systematic knowledge in MathWorld, adapted into fully computable form. Wolfram|Alpha gives sidebar links to MathWorld when appropriate.

### How does Wolfram|Alpha relate to the Mathematical Functions Site?

Wolfram|Alpha provides immediate algorithmic access to all of the over 300,000 formulas in the Mathematical Functions Site. Wolfram|Alpha also gives links to the Mathematical Functions Site.

### Who built Wolfram|Alpha?

An eclectic team led by Stephen Wolfram. For most of the pre-launch development period, the team had fewer than 100 members. The team includes experts in many fields and domains.

### How long did it take to build Wolfram|Alpha?

The Wolfram Language foundations that lie beneath Wolfram|Alpha were started in 1986. The full Wolfram|Alpha project started in 2005.

### When do you access my Facebook profile?

We only access your Facebook profile when you use Wolfram|Alpha Personal Analytics for Facebook, unless you have enabled Historical Analytics, in which case we will access your profile periodically. Your data is securely stored on our servers and is protected by industry-standard encryption. Your profile is only accessible to you, through Wolfram|Alpha Personal Analytics for Facebook.

### Who can see my Personal Analytics for Facebook reports?

By default, your reports are private to you, unless you explicitly publish results from them.

If you choose to become a Data Donor, data from your reports is shared with our researchers in accordance with that program.

## Historical Analytics and Data Donation

### What is Historical Analytics?

Historical Analytics provides additional results for Facebook queries that show you how your network changes over time.

Your Facebook data is periodically archived and will be used to generate new historical comparisons each time you create a report.

You can begin privately archiving your data for Historical Analytics at any time. Note, however, that historical comparisons are an upcoming feature and additional Historical Analytics pods are not yet available.

### What does it mean to be a Data Donor?

Data Donors support our research on personal analytics and sociometrics by donating their personal analytics data to our research collection.

Enabling this option adds your Facebook data to our research collection. Your personal information will never be published, though it will be accessible to our research team for their continued research in personal analytics and sociometrics. Your information will never be sold or used for marketing purposes.

If at any time you want to stop your future data from being archived, you can turn off data donation in your preferences.

### What data do you store if I become a Data Donor?

The data stored will include all data used to generate your Facebook report. It will not include any photos or private messages. As with all personal data we store, this data will be used for the limited purpose of enhancing user experience with our personal analytics products.

## Features and Support

### How can I delete my account?

For the immediate future, send a message to info@wolframalpha.com, and your Wolfram ID will be deleted from our system manually. Soon there will be an option for you to do this yourself.

### Why isn't the Facebook report working on the Wolfram|Alpha mobile app?

Wolfram|Alpha Personal Analytics for Facebook is only currently available on the Wolfram|Alpha website through a standard desktop browser.

### Is there support for other languages?

The Wolfram|Alpha report is only available in English at this time. However, if you use Facebook in another language, we will analyze the data accordingly (e.g. for word clouds, etc.).

### Can I run this report on Facebook pages?

Not at present. Facebook page analysis is being planned. Contact business@wolframalpha.com if you are interested in page analysis.

### Will there be Personal Analytics reports for other social media?

Stay tuned.

### Why is my Facebook report different than it used to be?

Facebook has changed what information is available through their API; we display the information we have access to.
