MDDD is a simple method to discuss problems with AI, develop solutions, and keep a record of your work. That record is called a docbase and is stored as files on your computer which can be read by both you and an AI assistant. This creates a permanent memory, allowing you to pick projects up and put them down again, and bring a fresh AI up to speed quickly.
Small business owners, contractors, and anyone managing projects that stretch across weeks and months.
Ever had a great idea in the middle of working on something, and forgotten it by the time you had a second to think? Ever solved the small problem only to forget where you were on the big one? Ever come back to a project after a few months off and had no idea where to start?
Then MDDD is for you.

Because I asked myself: how can I use AI to do something complicated and actually useful over time?
MDDD, Markdown-Driven Development, is the method I'm actively developing to answer that question, and so far it's working really well for me.
I'm a long time Excel user, and I'm finally building my first real app. I'm also a construction project manager by profession, so I started treating my app like a project. MDDD is the infrastructure I built to do the work.
I realized while working on my app that other people might find MDDD useful, and then I helped a friend with it. So I paused the app for about a week to build this website from scratch (my first time), create the whole MDDD package, and write these words (yes, I wrote them myself one keystroke at a time).
My friend Michael owns a construction company. He's the first person (other than me) to use MDDD, and his first session took about two hours. When it was done, he had an equipment checklist he could use the next day, and an idea to make more and turn them into a simple app for his employees. A few days later he started planning to document his estimating process, so he could teach someone else to do it.
For the curious do-it-yourselfers.
