Guides
Guides for running Swift, Python, JavaScript, Go, and Rust in Notepad.exe, plus Linux, the assistant, and a local Mac app.
Run Swift on a Mac without an Xcode project
Command-R runs a Swift note without creating an Xcode project.
Prototype SwiftUI without an Xcode project
SwiftUI and UIKit templates run in the iOS Simulator next to the source.
Run Python on a Mac without a project
Your interpreter, a .venv the app creates, and pip for the note's dependencies.
Run JavaScript on a Mac with Bun
One file, Command-R, and Bun. A Node project can wait until you need it.
Test code on Linux from a Mac
Swift and Go cross-compile, then run in a Linux container. Python, Bun, and Rust run there too.
Where the assistant runs
On-Device Model stays on the Mac. Notepad AI, the default, sends chat through Cloudflare.
Export a SwiftUI Mac app
Distribute App writes a local Mac app from a macOS Swift note. App Store upload stays in Xcode.
Organize code snippets on a Mac
Search the Library, tag a note, and pin the window above your other apps.
Run Go on a Mac without creating a module
A new Go note gets a go.mod from the app. Command-R runs it.
