Kaelio
A fast, lightweight Markdown editor built with Tauri 2 + Rust. Open any .md file and get live preview, Mermaid diagrams, math, and Git-backed history — no vault, no config, just open and go.
Feature map
Grouped notes for the current sample.
Markdown
- Mermaid (click-to-zoom), KaTeX ($…$, $$…$$), YAML frontmatter, footnotes, wikilinks, anchor navigation, copy-heading-link.
Files
- sidebar browser, context menu, file search (Cmd+Shift+F), content search (Cmd+Opt+F), command palette, breadcrumbs, recent files. Drag files or folders from Finder onto a sidebar folder to copy them in; drag onto the editor to open.
Image viewing

Export
- copy as formatted HTML / raw / plain; image & PDF from the preview (PNG/JPG/PDF); Markdown to PDF/DOCX via Pandoc + Typst
Split view
- Toggle a second pane (⊟) beside the editor — a full editor with its own tabs and edit/preview toggle. Cmd+S saves whichever pane has focus.
File compare
- Right-click → Open in Split Window, or Select for Compare → Compare with Selected to view two files side by side.
Soft wrap
- View → Soft Wrap: Off, Window Width, or Page Guide (a configurable guide column) — long lines stop clipping.
Preview search
- Cmd+F in reading view highlights matches with next/prev navigation.
HTML rendering
- Open and render .html files inline in the preview pane.
Custom fonts & sizes
- Pick your reading font and size, and zoom each split pane independently.
Custom themes
- Built-in Everforest and Nord themes plus your own custom theme — beyond mx's stock palette.
Session restore
