Tagdown Editor

Tagdown Editor is a macOS desktop app for structured note-taking using a markdown-based format called Tagdown. It supports standard markdown plus enriched features like tags, wikilinks, callouts, tabs, math, diagrams, live queries, presentations, and website publishing. Notes are stored as .md files locally, giving users full ownership and offline access. It includes features like version history, a daily journal, task management, and integrates a CLI and MCP server for AI-assisted note interaction. The app is open source and written in Rust and TypeScript using Tauri.
