Introducing Extend UI — open-source components for document agents
- 14 components & examples for PDF, DOCX, and XLSX viewers, plus bounding box citations, file upload, e-signature, and more - fully customizable - MIT licensed
when we started, we tried every file viewer and document component library we could find
unfortunately, none of them had all the functionality (and polish) that we wanted, so we ended up building our own for @ExtendHQ
it was only ever meant to be internal, but enough customers kept asking for it that we decided to give it back to the community
it's useful for building agents, user-facing document flows, or internal tools
we use and maintain it for Extend ourselves, so it'll keep getting better over time (and it's battle tested on millions of pages running through our system every day)
it also works with design system agents like @magicpatterns for faster exploration and prototyping
available today on the @shadcn component registry! some examples in 🧵
