# User Access

Manage user permissions and control access levels

In JTheta Annotate, each user role can be designated as either an Annotator or a Reviewer within a project.

When creating a project, you’ll need to specify each users position in the project, assigning them as either an Annotator or a Reviewer.

**Admin Role**

In JTheta, the Admin role has the authority to manage users, assign annotators and reviewers, and control task distribution within projects. The Admin ensures that annotation and review workflows are properly assigned based on the Round Robin or other distribution methods.

**Annotator Role**

The Annotator role in JTheta Annotate is responsible for labeling and tagging data within a project. Annotators use the platform's tools to create annotations such as bounding boxes, polygons, or other markers, depending on the project's requirements. Their primary task is to accurately and efficiently label data to ensure high-quality input for AI and machine learning models.

**Reviewer Role**

The Reviewer role in JTheta Annotate is responsible for quality assurance within a project. Reviewers carefully inspect the annotations created by Annotators to ensure accuracy, consistency, and alignment with project guidelines. They can approve, modify, or reject annotations as needed, playing a critical role in maintaining high-quality data for AI and machine learning models.
