## What it is
Extend UI is an open-source React component library (distributed via the shadcn registry) for building document-heavy product interfaces: PDF, DOCX, XLSX, and CSV viewers, file upload, file browsing, e-signature, bounding-box citations, and schema builders. Components are copied into your project as editable source built on React and Tailwind.

## Use cases
- add a pdf viewer to my react app
- build a document review interface for extracted data
- let users upload and validate documents with drag and drop
- preview excel spreadsheets in the browser
- show bounding box citations over scanned documents
- build a finder-style file browser for s3 objects
- let users split long pdfs into smaller documents
- build an extraction schema editor with  output

## When to choose
- you are building document-heavy products like parsers, IDP tools, or agent-facing document workflows
- you want shadcn-style source components you can fully customize with your own design system
- you need viewers plus review surfaces (annotations, e-signature, validation) in one cohesive kit

## When to avoid
- you need a drop-in npm package with a stable API rather than copied source code
- your app is not React/Tailwind based
- you only need a minimal PDF viewer and don't want the broader document toolkit
