AsciidocFX

AsciidocFX is a cross‑platform editor built on JavaFX 19 that lets users write Asciidoc source and generate finished publications. It provides a real‑time preview pane and supports output formats such as PDF, HTML, ePub, Mobi and DocBook, making it suitable for creating books, technical documents and slide decks. The editor includes a pseudo‑terminal emulator, theme switching between dark and light modes, and a set of extensions for diagrams (PlantUML, Mermaid, ditaa), mathematics (MathJax), file system trees, and JavaFX charts, as well as converters for Reveal.js and Deck.js slides.

The tool targets authors, technical writers and educators who need a single environment for authoring and exporting Asciidoc content without switching between separate applications. Its multi‑platform availability on Windows, macOS and Linux allows users to work on their preferred operating system while retaining a consistent workflow.

Distinctive aspects include built‑in extensions for visual content, live preview that updates as the document is edited, and a terminal‑like interface for running commands within the editor. AsciidocFX has been recognized with the Duke’s Choice Award in 2015, reflecting its stability and feature set.
