GenOffice
An AI-native office suite for macOS and Windows
GenOffice is an AI-native desktop office suite for macOS and Windows built as five Electron applications sharing a common engine layer. It provides dedicated editors for Word documents, Excel spreadsheets, PowerPoint presentations, and PDFs, plus a shell that hosts the suite. AI editing is integrated directly into document state instead of being limited to a separate chatbot. Documents support block-level edits and diffs, while sheets, slides, and PDFs expose their state to a tool-calling agent. The suite uses specialized engines for DOCX, XLSX, PPTX, and PDF parsing, rendering, editing, and export. Its round-trip design applies narrow patches so untouched portions of original files remain intact. Shared packages provide agent logic, model streaming, search, internationalization, project storage, and interface components. -

Pandoc
The universal markup converter
Pandoc is a universal document converter able to convert files from a multitude of markup formats into another. With Pandoc, you have a swiss-army knife of a converter, able to convert practically any markup format into any other. Pandoc contains a Haskell library for conversions as well as a command-line tool that uses this library. It can convert to and from just about anything-- lightweight markup formats, HTML formats, documentation formats, ebooks, TeX formats, word processor formats and so much more. It understands several useful markdown syntax extensions, such as document metadata, footnotes, tables, and more. If you want strict markdown compatibility however, these extensions can be turned off. Pandoc is no doubt powerful and customizable, but it is important to note that its intermediate representation of a document is less expressive than many of the formats, so it may not produce perfect conversions every time. -

It also provides a CLI and an installable agent skill for Codex, Claude, and compatible agent environments. -

Dompdf
HTML to PDF converter for PHP
dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries. -

TinyTeX releases
Windows/macOS/Linux binaries and installation methods of TinyTeX
A lightweight, cross-platform, portable, and easy-to-maintain LaTeX distribution based on TeX Live. TinyTeX is a custom LaTeX distribution based on TeX Live that is small in size but functions well in most cases, especially for R users. If you run into the problem of missing LaTeX packages, it should be super clear to you what you need to do (in fact, R users won’t need to do anything). You only install LaTeX packages you actually need. Currently, TinyTeX works best for R users. Other users can use it, too, it is just that missing LaTeX packages won’t be automatically installed, and you need to install them manually. Or you can go to the extreme to install all packages (see FAQ 3 for how), but remember there are thousands of them. Installing or running TinyTeX does not require admin privileges, which means you no longer need sudo or your IT. You can even run TinyTeX from a Flash drive.
