Getting Started

Welcome to doors94

A Windows 95-style sandbox for learning AI agent design through hands-on experimentation.

Create, test, and compare custom AI agents in a nostalgic retro computing environment. No install, no account—just open the desktop, start playing, and see how it all works under the hood.

Click "Launch doors94" to boot into the desktop. Or explore the repo to fork, tweak, and extend the system yourself.
About doors94

What it is

doors94 is an educational playground disguised as a fake operating system. It helps you design small, focused AI agents and see how structured descriptions turn into behavior.

Why use it

Instead of abstract theory, you learn prompt and agent design by play: tweak manifests, chat with agents, compare them to raw GPT, and iterate.

How it works

  • Create an agent with the Agent Creator wizard.
  • Chat with it from the desktop like any other app.
  • Use the Playground to compare it side-by-side with raw GPT.
  • Refine the manifest and repeat.

Features

  • Agent Creator wizard for building custom AI agents.
  • Playground for side-by-side comparisons with raw GPT.
  • Manage Agents to manage, duplicate, and delete agents.
  • Authentic Windows 95-style desktop, windows, and taskbar.
  • Built-in tutorial and real-time validation while you edit.

Under the hood, agents are defined as manifests that compile into system prompts, so you can see exactly how structure shapes behavior.

Open-source by design
