Notepad.exe

About
Notepad.exe is a minimalistic yet powerful development environment that allows you to run Swift, Python and JavaScript code in 3 seconds.You open the file, press ⌘R and get the result - without creating a project, without configuration files and without waiting for indexing.This is an IDE for developers who want to write code rather than customize tools.
Xcode is heavy and slow to launch for small projects or experiments.Text editors cannot run code with one button.Notepad.exe offers a happy medium - instant launch, support for three languages, and AI suggestions that work locally.
Features:
Instant launch and execution:
• The application opens instantly, without a splash screen or long indexing.
• Code in Swift, Python or JavaScript is executed with one command (⌘R).
• Supports three languages out of the box:
• Swift – for iOS and macOS applications.
• Python – for scripting and automation.
• javascript – for web projects.
Progressive Difficulty:
• For quick tasks: Just open the file and run - reasonable default settings work.
• For advanced scenarios: You can configure custom interpreters, build flags and targets.
• For serious projects: Export the finished .app for your own use.
• AI assistant with local work:
• Hints, refactorings and code explanations.
• Main thing: The AI model runs completely on your device.The code never leaves your Mac—it's secure and private.
Integration with iOS Simulator and SwiftPM:
• iOS Simulator: Prototype SwiftUI and UIKit screens in the simulator without opening Xcode.
• Swift Package Manager: Edit SwiftPM packages and run them on macOS or Linux (Linux subsystem is installed automatically).
Additional features:
• Notes Library: A library for organizing scripts and notes.
• Pin to front: Pin the window on top of all windows for reference code work.
• Share as image: Turn a piece of code into a beautiful image for publication (with syntax highlighting).
