Custom Annotation Schema Builder

via “custom annotation schema definition and validation”

Enterprise AI data labeling with managed annotation workforce.

Unique: Provides both visual schema builder and JSON schema support with automatic annotator-facing documentation generation, reducing the gap between data engineers defining schemas and annotators understanding requirements

vs others: More flexible than fixed-template annotation platforms because it supports arbitrary schema hierarchies and conditional logic, whereas platforms like Labelbox have limited schema customization without custom code
