Johnny.Decimal is a system that helps you be more organised. It gives you a simple structure so you can easily find your stuff. Everything gets an ID like 12.12 Home insurance & claims.

The system is free. Use it at home or work. It works best with an app like Obsidian, but use whatever you want. You control your own data.

We sell systems and training that make your life easier. Create a free account and get access to more content and tools. I'll add you to our mailing list: one-click unsubscribe, view our privacy policy.

Our pre-built systems save you time: we spent hundreds of hours designing them so you don't have to.

Everyone has life admin, spread across cloud drives, download folders, and years of email. The Life Admin System gives you a place for everything: download it and move in. Our AI server can do that for you.

You started a business because there's a thing that you do better than anyone else. The Small Business System deals with the boring admin that we all share – it runs our business.

You can know exactly where your house insurance policy is, and when it's due – and still forget to renew it. There's so much to do that it's hard to keep track of what comes next.

In our 5-hour Task and Project Management course, I show you how to achieve a 'comfortable awareness' of everything on your plate. These processes drive my life and business. My todo list isn't stressful.

The Life Admin System covers the things we all do. It can't cover your hobbies, your side hustle, or that tennis club you manage. In our 5-hour Workshop, my partner Lucy takes apart her own life and rebuilds it as a Johnny.Decimal system. You build yours alongside her – by the end, you have a working system of your own.

They're two of the six courses in Johnny.Decimal University, all included with our Pro membership. No subscription.

There's a collection of free, open-source Utilities that make working with the Johnny.Decimal system easier.

Ask your AI where your insurance renewal goes and it's only guessing. Connect it to JDHQ and it reads the system directly. It can 'move you in' to Life Admin or Small Business in a safe, guided process.

“Over the past day and a half Claude has completely organised my SBS and made a good start on my LAS which I'd tried to do myself 3 times … [It] has been able to save me literally hours (or more realistically just do something I'd never have got done).”

The server has access to about half a million words of my writing spanning five years of documentation, blog, video transcripts, and responses to forum questions. It's like it can 'read my mind'.

There's also an API, and a Mac app under development.

The Johnny.Decimal system Documentation is here. Start with the Introduction and work your way through it.

There's a Blog. The latest post is MCP server 'move in' is live, published earlier today.
