## What it is
Yank Note is a highly extensible desktop Markdown editor built on Electron and the Monaco editor, with features like version control, document encryption, runnable code blocks, mind maps, and an AI Copilot supporting multiple LLM providers. It stores data as plain local Markdown files and can be extended with user-written plugins and macros.

## Use cases
- write and organize markdown notes locally
- edit markdown with vscode-like experience
- encrypt private notes with per-file passwords
- run code snippets inside documents
- use AI to complete and rewrite text
- track document version history
- embed diagrams like mermaid, plantuml, drawio in notes

## When to choose
- you want a local-first markdown note app with rich extensions
- you need AI-assisted writing with your own LLM provider
- you want runnable code blocks and embedded widgets in documents
- you need encrypted markdown files

## When to avoid
- you need mobile or web deployment
- you require strict security sandboxing when opening untrusted files
- you need collaborative real-time editing
