Macaroni

Macaroni is a read-only Markdown viewer for Mac that watches folders to show what AI agents changed.

Macaroni is a fast, read-only Markdown viewer for macOS designed for reading what AI agents write. Point it at a project folder to watch the tree, list what changed since you last read it, and see what moved in an inbox-style feed. It renders GitHub Flavoured Markdown, Mermaid diagrams, KaTeX maths, tables, task lists, and highlighted code offline. Made for tools like Claude Code, Cursor, and Codex, it runs natively on Apple silicon and Intel. The app requires no account, features no networking code, and keeps files untouched while operating beside your terminal.
