Introduction

Retab UI is an open source component library for building document AI product surfaces on top of Retab. It provides headless, unstyled React components that render the results of Retab's six core primitives, so you can drop a viewer into your own app and theme it to match your product.

The components are installed as source through the shadcn registry — you own the code, you control the styling.

The six primitives

• Parse — render extracted per-page text and markdown from a document.
• Extraction — render structured JSON pulled from a document against a schema, with optional source grounding.
• Edit — render AI-filled form fields, overlaid on the document by bounding box.
• Classification — render a document's predicted category and reasoning.
• Partition — render a document segmented into keyed chunks by page range.
• Split — render a document divided into named subdocuments by page range.

Base primitives

The shared base components (button, tabs, dialog, popover, tooltip, sidebar, and the rest) are standard shadcn/ui primitives. Icons come from Lucide.
