Extend UI: Open-Source Component Library for Document Viewers Released
Extend AI has open-sourced Extend UI, a 14-component MIT-licensed library for building PDF, DOCX, and XLSX viewers with features like bounding box citations and e-signatures. The company developed the toolkit internally for its document processing platform after finding existing solutions lacked desired functionality and polish. The release aims to address a gap in scalable document viewing components for developers building document processing applications.
Extend AI announced the open-source release of Extend UI, a customizable component library designed for modern document applications. The toolkit includes 14 components and examples supporting PDF, DOCX, and XLSX file formats, along with features such as bounding box citations, file upload, and e-signature capabilities. The company initially built the library for internal use at Extend.ai but decided to open-source it after multiple customers requested access. According to the announcement, the developers found that existing file viewer and document component libraries lacked the comprehensive functionality and polish they required, making document viewing at scale a non-trivial engineering challenge. The library is maintained by Extend's team, which has resolved numerous edge cases from processing millions of pages daily through their platform.
