Extensions

Review Extensions let you customize the document review experience by adding custom behavior and UI to the Review Interface. Extensions are JavaScript/TypeScript modules that are loaded at startup and have access to the full Review Interface API.

You can use the Review Extensions framework to:

• Execute custom code in response to application lifecycle events
• Add custom UI panels (cards) in docks around the document viewer
• Add toolbar buttons and controls
• Add right-click context menu items
• Render custom highlights and overlays on document content
• Register custom viewer types
• Conditionally load based on application context or version
