A Markdown viewer that shows what changed since you read it
Open one Markdown file, or point Macaroni at a folder: it lists what changed since you last read it, even while it was closed, and shows the diff line by line against the version you last read, with no git involved. Made for reading what AI agents like Claude Code write. Mermaid, KaTeX and Quick Look included. Read-only, sandboxed, no account. $14.99 once on the Mac App Store.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
