# Step 4: Why Voyant and Lexos?

In this tutorial, the tools [**Voyant**](https://voyant-tools.org/) and [**Lexos**](http://lexos.wheatoncollege.edu/upload) are being used. They have been chosen because they are "out of the box," meaning they don't require any coding, they are relatively easy to use, and they have many capabilities. As such, they are great tools for getting started in text analysis.  

Generally speaking, "out of the box" tools tend to be blunter instruments in that they do not allow for the level of customization and specificity that using coding and scripting languages like Python and R do. Consequently, if you want to run more in-depth text analysis queries, you would eventually need to gain some coding and scripting skills. If tools like Voyant and Lexos serve all of your text analysis requirements, then they might be all you need.

Lexos, which is more complex than Voyant, allows some more in-depth work and can be used for scraping, scrubbing, and cutting text in addition to conducting analyses. Voyant has a flexible and friendly interface that provides a lot of different ways into a text. In this tutorial, you will learn about a way in which Lexos and Voyant work well together.

When first using Voyant and Lexos, it is good to look over their guides and other helpful information. Voyant has an [extensive guide](https://voyant-tools.org/docs/#!/guide/about), with the [tools list](https://voyant-tools.org/docs/#!/guide/tools) and tool instructions being particularly helpful. The question marks on the Voyant interface also provide information. Lexos has helpful information within the tool. Click on a question mark to learn what something does, or click on "Help" in the top right of the navigation bar to open the help window on the left.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bcds.gitbook.io/learn/tutorials/text-analysis/introduction-to-text-analysis/voyant-lexos.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
