# Building experiments with EmotivPRO Builder
EmotivPRO Builder (Builder) is an online neuroscience experiment building platform designed for use with Emotiv's EEG headsets.
It's a simple, user-friendly platform that allows you to create neuroscience experiments from scratch by building phases: calibration, instruction, and stimuli phases.
Each phase is built by including different elements — like video, audio, and text — which you can upload from your computer. You can also customize the elements in an experiment so the participant(s) can see them in different ways: including randomizations and looping.
When you've finished building an experiment, you can publish it to EmotivPRO Player (privately) for use in-house or remotely, or publicly to LABS Citizen Science.
As a participant plays an experiment, a live EEG recording is collected, fully time-marked, and saved securely and anonymously in EMOTIV Cloud.

## 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://emotiv.gitbook.io/emotivpro-v3/emotivpro-builder/building-experiments-with-emotivpro-builder.md?ask=&goal=
```
`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.
