A method for working with AI that produces reliable results — not lucky ones.
Brief AI like a colleague, not a search engine
The difference between AI that produces generic advice and AI that produces something only you could have written is fifteen minutes of setup.
Spot the answers that are confidently wrong
AI is wrong often enough that you need a system for catching it — not a feeling.
Make AI argue with itself
The best ideas often come from two AIs disagreeing. Here's how to set that up.
Build things you couldn't build before
A teacher built a quiz that branched by ability. A paralegal wrote a personal statement that sounded like her. You don't need to know code — you need to know what you want.
Real projects, real outcomes
Each chapter draws on a project I actually built. These four shaped the
book — no team, no budget, no engineering background. AI made them possible.
Plyego
A publishing platform I built and now run as a product. Upload a Word
manuscript, get a print-ready PDF and a Kindle-ready EPUB. AI checks
cross-references, citations, glossary terms, and structural fidelity
along the way. Different standards packs handle different kinds of
book — practical guides, technical references, more to come. Plyego
produced this book and the other one.
Tracks portfolios against rules I set when thinking clearly. Flags
drift. Records every decision and why. Runs quietly between monthly
reviews. The next version will implement investment strategies based
on my own research, with proper attribution analysis to see what's
actually working — and what's not.
A house-buying decision framework
A questionnaire (200+ questions), a locked brief that can't silently
drift, a three-layer triage that filters every new listing, and a
red-team challenge for every serious candidate. Built to stop me
falling for the wrong property. Still running, still doing its job.
A personal portfolio system
A repo I run as my own command centre. It holds my AI stack
decisions, my brand strategy, what I'm building and why, and the
rules I use to coordinate across two books, a platform, and a day
job. AI helps me keep it honest — surfacing inconsistencies,
challenging weak rationale, holding me to the cool-off periods I've
committed to.
