A native macOS markdown editor specialized for AI context management. Live editor on the left (codemirror 6), rendered preview on the right (markdown-it + shiki + mermaid). Minimal Chrome, full catppuccin + matcha themes, macOS vibrancy, orange octopus mascot. ~10 MB bundle.

Works with claude, chatgpt, gemini, your local agent — anywhere that reads plain markdown.

Features:

• live preview — debounced ~50 ms render with code blocks (shiki) and mermaid diagrams
• 5 themes — catppuccin latte / frappé / macchiato / mocha + matcha (washi paper + kelly green) + system auto-switch
• reading mode — flips to distraction-free preview-only with iA-style typography
• command palette — fuzzy-searchable, grouped by category
• find / replace — opens a themed codemirror search panel
• folder sidebar — load a folder of .md, fuzzy-search across the tree, click to load
• share to AI — copies the current markdown to your clipboard, paste anywhere
• export to PDF — renders preview-styled HTML, opens system print dialog
• macOS vibrancy with opt-in transparency
• auto-save off by default — commits. trust your fingers, not background daemons.
• fully keyboard-driven — every command has a shortcut, palette covers the rest
