# Wolfram|Alpha: Computed Answers, Not Web Search

> Wolfram|Alpha computes answers from the Wolfram Knowledgebase, its own edited data, and does not crawl the web. What this means for site owners.

Wolfram|Alpha is a computational knowledge engine that computes answers from its own edited data, the Wolfram Knowledgebase, and does not search the web. A website cannot rank in it, and it documents no crawler to allow or block. If you have data that belongs in it, you can suggest the data to its team.

## How Wolfram|Alpha gets its answers

The [Wolfram|Alpha FAQ](https://www.wolframalpha.com/faqs) says that Wolfram|Alpha is not a search engine. It does computations from the Wolfram Knowledgebase instead of searching the web and returning links. The FAQ also says that Wolfram|Alpha does not get its data from the web:

- The data comes from the internal knowledgebase.
- Some of that data comes from official public or private websites, but most comes from systematic primary sources.
- The Wolfram|Alpha team combines the data and reviews it.

Each relevant results page has a Sources button. It lists background sources and references.

## Who makes it

Wolfram Alpha LLC is a privately held spinoff of Wolfram Research, Inc., the company behind Mathematica and the Wolfram Language (FAQ). A team led by Stephen Wolfram built it.

## Wolfram|Alpha in AI tools

AI apps can call the [Wolfram|Alpha LLM API](https://products.wolframalpha.com/llm-api/documentation) at `https://www.wolframalpha.com/api/v1/llm-api`. It returns plain-text results for a language model, with a link back to the full results page on wolframalpha.com. So an AI tool that uses Wolfram|Alpha gets a wolframalpha.com link to show as the source.

The FAQ says that you cite Wolfram|Alpha itself as the source, with the time or place of the query, because they can change the result.

## What a site owner can do

- Wolfram|Alpha does not crawl the web for its answers. There is no Wolfram|Alpha token for robots.txt.
- If you have data that belongs in Wolfram|Alpha, send it to the Wolfram|Alpha team. Use the feedback form at the bottom of a results page, or the [contact page](https://www.wolframalpha.com/contact-us). The Wolfram|Alpha team reviews all of its data, so every contribution goes through a data review.
