What is it?

Ely Office is a set of desktop applications written in Rust on the GPUI UI framework. It covers word processing (DOCX, ODT), spreadsheets (XLSX, ODS, CSV), presentations (PPTX, ODP), PDF reading and editing with OCR and signatures, a Git client, and a Markdown editor. Documents are opened from and saved to ordinary folders on the local machine, and the apps do not require an account or a cloud service.

The office apps use LibreOfficeKit as their document engine, while ElyPDF is built on MuPDF and Tesseract. ElyMark renders Markdown with markdown-rs, RaTeX for math and mermaid-rs-renderer for diagrams. The build scripts fetch and compile patched upstream LibreOffice, MuPDF and Git at pinned versions. The project currently documents a macOS build and packaging path; Linux and Windows recipes are included but have not been run.
