Userbrain works with any prototyping tool that allows you to share a public link. Simply put, if you can link to it, you can test it. 

Here's how to test your Sketch prototypes with Userbrain: 

1. View your document in Sketch Cloud. 

2. Open the Document Settings by hovering over the document you wish to share and click on the More options icon (the three dots in the top-right corner)  

3. When you get to "Who can view this document?" Select "Anyone with the link and people you've invited"

4. Make sure that all the checkboxes below are deselected. 

How to disable hotspots 

Clicking anywhere on the screen while viewing your prototype will highlight any Hotspots or Links. To share a Prototype preview without hotspots enabled, hover over the Prototype thumbnail in the documents overview, click on the "…" button and choose "Copy link to Prototype with Hotspots disabled"

If for any reason there's a problem while using Sketch cloud, you can test your Sketch prototypes on other tools as well. 

First, you need access to one of these collaborating/prototyping tools in addition to Sketch: 

• InVision

• Framer

• Zeplin 

• Flinto Lite

• Axure 

• Adobe XD
