1.5.0

Version 1.5 rebuilds the coding assistant, adds ChatGPT subscription sign-in, supports more languages and project types, and fixes rough edges throughout the app.

Doctor Marvin, rebuilt

The coding assistant got a full rewrite, and it is the biggest change in this release. Answers stream in as they are written, and it can build and run your project, read the output, and edit your files to help you fix errors without leaving the app.

Notepad AI, out of the box

The assistant is ready as soon as you open it. Sign in with a ChatGPT Plus or Pro subscription and use it without an API key, keep using "ChatGPT (API)" if you prefer keys, or pick from more cloud and local models.

More languages

Go is now first-class, with templates, completion, dependencies, and Linux runs. TypeScript and JavaScript build and run with full editor integration, and Python gained semantic highlighting.

Plain text, anything

Open pretty much any file as plain text, with highlighting when the type is known. Drop folders on the Dock icon, and drag, rename, and filter files right in the navigator.

Swift packages, directly

Bookmark Swift packages in your Library, pick the product or target to build from the toolbar, and manage dependencies from project settings. New templates cover Swift Package executables and libraries.

Build and run, including Linux

Cross-compile Swift, Python, and Go to Linux from your Mac, no VM required. The new Activity viewer in the toolbar shows builds, downloads, and other background work as it happens.

iOS simulator

Quick Help and the Simulator now share one inspector panel. Simulator runs are more dependable: the app waits for devices to boot, prefers already-booted hardware, and reports launch failures clearly.

Terminal

The built-in terminal now uses Ghostty. Rendering is faster, Unicode behaves better, and colors follow your editor theme.

Polish and stability

The sidebar is now a Library with search and swipe actions, and code completion is snappier.

v1.5.0Jul 12, 2026

Notepad.exe 1.5.0

I rebuilt the coding assistant from scratch, added ChatGPT sign-in so you can skip the API key, brought in more languages and project types, and fixed rough edges throughout the app.

Doctor Marvin, rebuilt

The assistant is the biggest change in this release, and it got a full rewrite. Answers stream in as they are written, and it can build and run your project, read the output, and edit your files to help you fix errors without leaving the app.

Notepad AI, out of the box

It works the moment you open it. Sign in with a ChatGPT Plus or Pro subscription and use it with no API key, stick with "ChatGPT (API)" if you prefer your own keys, or pick from a longer list of cloud and local models.

More languages

Go is now first-class: templates, completion, dependencies, and Linux runs. TypeScript and JavaScript build and run with full editor support, and Python picked up semantic highlighting.

Plain text, anything

Open almost any file as plain text, with highlighting when Notepad knows the type. Drop folders on the Dock icon, then drag, rename, and filter files right in the navigator.

Swift packages, directly

Bookmark Swift packages in your Library, pick the product or target to build from the toolbar, and manage dependencies from project settings. New templates cover Swift Package executables and libraries.

Build and run, including Linux

Cross-compile Swift, Python, and Go to Linux straight from your Mac, without spinning up a VM. The new Activity viewer in the toolbar shows builds, downloads, and other background work while it happens.

iOS simulator

Quick Help and the Simulator now share one inspector panel. Simulator runs are steadier too: the app waits for devices to boot, prefers hardware that is already running, and tells you clearly when a launch fails.

Terminal

The built-in terminal now runs on Ghostty. Rendering is faster, Unicode behaves, and colors follow your editor theme.

Polish and stability

The sidebar is now a Library with search and swipe actions, and code completion is snappier.

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
