# About previewing The preview tool allows you to see how each phase of an experiment looks and plays before you decide to publish it. To preview an experiment: 1. Click **Edit** on the experiment you want to preview. The editing screen for the experiment will open. 2. Click on the **Preview** button at the top right-hand corner of the screen. 3. A preview of the experiment will open in a new browser window. --- # Agent Instructions: 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.
