key-notes

A super simple, minimal native desktop markdown notes app. Limited to 10 notes, stored locally.

Features

• Markdown preview (live render)
• Mermaid diagram support
• Keyboard shortcuts
• Local file storage (plain .md files)

Quick start

pip3 install pywebview
python3 main.py

How it works

The app uses pywebview to open a native desktop window pointing at a built-in HTTP server. Notes are stored as .md files in a notes/ folder (created automatically on first run with starter content).
