Getting Started with Annotator

Learn the basics of using Annotator to get all your deep learning projects up and running. This document covers signing up, recommended browser, opening assigned cases, and troubleshooting.

Signing Up

Please follow the directions to get started:

Go to and click on the 'Sign up' button.

Identity Providers

You can sign up using your Google account, Github account, or use your email address. Important: If you've gotten an email invitation to a project, make sure to use that email to sign in. If you get an error message after signing in,double check the invitation email.

Signing In

If you've gotten an email invitation to a project, just click on the link for access. Make sure to use the email from the invitation to sign in.

For example, if you got an invitation to your .edu address and you try to sign in with your gmail account, you won't be granted access. Signing in with the correct email will open the project and your cases.


Annotator is an HTML5 web application optimized for the latest Google Chrome browser. We highly recommend using Chrome on a laptop/desktop.


Annotator has been most extensively tested on MacOS, ChromeOS, and Ubuntu Linux, and we recommend at least 8GB of RAM.

Annotation on mobile devices is not supported but may be sufficient for global annotation. Mozilla Firefox has not been tested, but should probably work.

Your cases will be loaded automatically

Choose the appropriate dataset in the dropdown menu if there is more than one, eg. training and validation datasets
