Built by people who love a good, simple diagram.

SimpleDiagrams began as a friendly desktop app to help you explain things. Some people found it cool. Some people made nice diagrams.

But then it died.

Or rather, the platform it was built on died. Then there was silence across the land. And some made diagrams with other tools, but those diagrams looked dumb and everyone knew it.

But now it's back...

The dark time of dumb, boring diagrams has passed. SimpleDiagrams is back. We're releasing a new MacOS version, with the same basic UI you know and love. (Linux and Windows versions may follow later, we'll see.)

Who made SimpleD

SimpleDiagrams is made by McQuillen Interactive, a small, independent software studio in Melbourne, Australia. We've built tools for research, building performance, education, and teams doing serious work with complex systems.

...and we make tools for stupid simple diagrams.

Who it is for

Anyone who wants to communicate visually with a simple diagram.

Actually, scratch that. It's for:

Anyone who wants to friggin' crush it with most excellent diagrams and still feel like you can actually do something that you don't need AI for.

So, really, let's look at SimpleD as a way to hold on to your humanity.

How we work

We are a small studio. We intend to keep SimpleD easy and fun. We value simplicty in all things. We like working closely with early customers (contact us, please). We'll add complex features when the app needs it, but we'll have a good think before we do.
