Build 1.4.1877Go support

Go support is here.

Compiled, fast, zero config. Go is now a first-class citizen. Write Go, run Go.

What you get

  • Full syntax highlighting
  • Completion and diagnostics for Go code
  • Run packages and single-file experiments instantly
  • Works with the same Notes Library language filters
  • The same open-file-hit-⌘R workflow as Swift, Python, and JavaScript

Another language, same Notepad.exe rule: open a note, write code, hit run.

JavaScript support is here.

Bun-powered, zero config. JavaScript is a first-class citizen. Write JS, run JS.

What you get

  • Full syntax highlighting via Tree-sitter
  • Completion & errors through typescript-language-server
  • Run instantly — Bun handles execution
  • Works on macOS and Linux
  • Automatic Bun installation

Same philosophy as Swift and Python before it: open a note, write code, hit run.

Linux support. For real.

Cross-platform Swift, finally easy. Write Swift on your Mac, run it on Linux. Cross-compilation, VM management, toolchain setup — all handled, all invisible.

What actually works

  • Cross-compile Swift targeting Linux from macOS
  • Swift toolchains & Linux SDKs download automatically
  • Runs in actual Linux environments with smart caching
  • Python works too — not just Swift
  • Platform column in the Notes Library
v1.4 🐧
v1.3Sep 21, 2025

Coding Intelligence.

AI built right into the editor. Autocompletes, suggests fixes, helps you write faster. On-device, using Apple's ML frameworks — your code doesn't leave your Mac.

Also in 1.3: App Distribution. Export a fully functional macOS app from the editor. Plus better Swift / Python highlighting, package updates without leaving the app, and new themes.

v1.3 ✦ AI
v1.2Jun 25, 2025

Python support.

"When Python?" "I'll pay double for Python support." Every. Single. Day. Fine. You win.

What's new

  • Write Python. Run Python. That's it.
  • pip works (numpy, pandas, whatever)
  • Output shows up instantly
  • No virtualenv to negotiate with
Opened PyCharm. Waited. Created a project. Set up the interpreter… you know what? Screw it. I added Python support instead.
v1.2 🐍
v1.1Jun 8, 2025

iOS runtime.

Ready for WWDC experiments. iOS runtime is finally working perfectly. Build SwiftUI apps, work with UIKit, experiment with any iOS API. The simulator spins up automatically — no configuration, no project setup, no Xcode checkboxes.

v1.1 iOS
v1.0May 22, 2025

Introducing Notepad.exe.

A playful nod to Windows' classic text editor — but this notepad actually executes your code.

It's essentially a notepad that can execute your code. I wanted something that would feel lightweight and familiar, but with the power to actually run the code you're writing.

What made it special

  • Swift-first, everything optimised for it
  • Searchable, taggable snippet Library
  • Floating notes that hover above other apps
  • Swift Package Manager integration
  • Local AI assistance
