AsciiMark is a local-first viewer and editor for AsciiDoc and Markdown. It runs as a desktop app (Tauri) and as a Chrome extension, rendering everything on your device — no account, no server, no telemetry.

Purpose

A fast, keyboard-first way to read and write technical docs straight from your local files. AsciiMark treats your filesystem as the source of truth and works fully offline — your documents never leave your device.

Highlights

  • AsciiDoc (Asciidoctor) and Markdown (markdown-it) with Mermaid/Kroki diagrams and KaTeX math.
  • Split panes, VS Code–style preview tabs, and a Reader/Zen mode.
  • Quick Open, Command Palette, Go to Heading, Workspace Symbols, Find in Files.
  • Backlinks panel and workspace-wide heading search.
  • Multi-root workspaces, file-system watcher, recent files and favorites.
  • Local-first: no analytics, no telemetry, no backend.
