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 happens on your device; there is no account, no server, and no telemetry.
Purpose
AsciiMark reads and writes technical documents directly from local files. It treats the filesystem as the source of truth and works offline. Documents stay on your device.
Features
- 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.
