Notchkin

Hover over the notch and a panel slides down. Type your note, and it’s saved straight to your Mac. No window to open, no app to switch to – it’s already there when you need it.

Living up there with your notes is Notchkin himself, a passive-aggressive little sticky note who occasionally offers commentary that's somewhere between helpful and passive-aggressive. Mostly the latter.

What’s included:
• Rich text formatting, including bold, italic, underline, strikethrough, highlights, and links
• Checklists, bullet lists, and numbered lists
• Hashtags, tag filters, and instant search across your notes
• Find within a single note, not just across them
• Pinned notes for keeping important things at the top
• Quick Capture from any app with a global shortcut, plus Paste as New Note to turn your clipboard into a note instantly
• Export to RTF or Markdown, plus full backup and restore support
• Accent colors and font options to make it feel like yours

All notes are stored locally on your Mac, with no cloud sync or accounts required. 

Buy it once and forget it exists until you need it.
