Graphify without AI: turning a wiki into a navigable graph for zero tokens

A thousand linked notes and no overall view: no way to see which ideas are central, which are isolated, or how two distant concepts meet. When every link in a wiki is already explained inside the notes, a 160-line Python script is enough to build a complete graph, explored with Graphify, in 0.2 seconds and without spending a single token.

Stateful Corpus Research Loop: stop collecting sources

Knowing what to look for next, and above all when to stop. Instead of fixing 30 or 50 sources up front, you start from a small vetted corpus, turn it into structured knowledge, and let what it knows — and what it doesn't — pick the next search. The result: less redundancy, visible blind spots and a stopping criterion you can test.

I went looking for what I had really invented in 'Context'

How do you find out whether the method you have just spent months building already exists somewhere else, under another name? The approach comes down to a few moves: break the idea into mechanisms, search for the function rather than the vocabulary, step outside your own field and outside English, and decide in advance what a find has to change to count.

Pillar cards: keeping your memory alive so you can keep thinking

Producing fast with AI ends up eating the time you used to spend thinking. Here is a concrete setup to protect it: a small core of cards, kept alive by spaced repetition, then laid out on a table so a new idea can be put up against your own convictions. You leave with the entry test, the review rhythms and a way to start.

The deliverable is no longer the asset

Every new format feels like starting over: you reopen the last document, copy, rephrase, and two versions slowly drift apart. The cause isn't a missing tool, it's treating a deliverable as your source of truth. How to install a reusable layer between your sources and your documents, and what AI gains from it.

How I write my articles by talking to my phone

Your best article ideas die between the moment they turn up and the moment you sit down to write. Here is the setup that catches them while they are still warm: the voice to empty your head without putting anything in order, a session source to keep the raw material raw, AI to surface the gaps in ten seconds rather than in two days.

I wrote a product's ontology. Three times, I thought I was done.

Your team rebuilds the same product model for every question, every bug, every tender. Here is how to write it down once: several dozen objects, a few hundred rules, under six hours. And above all how to know you have finished — the three stopping criteria that look like proof of completeness and prove nothing, plus the one that holds.

Session sources: what your documents miss

Your documents never say everything. The fine-grained understanding of what happens on the ground stays in the PM's head. Session sources open a channel for pouring that informal knowledge into an AI Context — a hallway remark, a nuance picked up from a customer, a tension just starting to show — and turn dozens of micro-signals into notes, assumptions and better-framed decisions.

What Is a Thematic Note?

A thematic note is the link between a note system and writing. It doesn't pile up everything that touches a subject — it picks an angle and brings several atomic notes together to make a pattern, a tension or a line of argument visible. Not a folder, not an encyclopedia: a temporarily stable view onto a network of thought.

What is an atomic note?

"One idea per note" is the formula everyone knows, and it sends most people in the wrong direction. An atomic note is not a short note. It is a note with a single conceptual centre of gravity. Once you see that difference, it changes how you capture, rephrase, title and link. And in the end, how you write.

What is a glossary entry?

The same words travel between product, marketing, sales and leadership, and nobody gives them quite the same meaning. A glossary isn't a collection of textbook definitions: it's a tool for collective precision. It pins down the terms that carry decisions, protects the links between notes, and cuts the cost of conversations where everyone defends a different idea with the same vocabulary.

The art of capture

We pile up tabs, links and quick notes — and never read them again. The problem isn't the amount of information, it's that nothing is ever decided about what it becomes. This article separates capturing from building capital, and offers a simple rhythm for turning your captures into knowledge without drowning in them.

Flash Card

An excellent note base isn't enough if the ideas never get absorbed. A flash card isn't a small atomic note: it's a personal pillar of thought, recognised in the heat of the moment by its resonance, tested over time by experience and by new sources. Rare by definition, it holds up what you really want to carry in you.

The PM as Architect of Context

Most organisations know how to produce documents. They don't know how to bank the reasoning behind them. On every decision they start again almost from scratch. The PM as Context architect turns scattered customer knowledge — transcripts, objections, past calls, weak signals — into a reusable asset. The result: faster, sturdier decisions, and an advantage competitors cannot copy overnight.

AI Wiki: why I built a knowledge base maintained by an AI

Classic RAG starts from scratch with every question. By building an AI Wiki — a persistent wiki maintained by an LLM — you capitalize on domain knowledge once and for all. Atomic notes, links between concepts, contradiction detection: knowledge is compiled, not rediscovered. Lessons learned from 950 notes extracted from industrial maintenance sources, with calibration insights and concrete use cases.

The second brain is a dead end for product management

Managing product opportunities inside a borderless network of notes means losing control: errors propagate silently, the AI context window blows up, and contradictions and decisions become impossible to find. The bounded context — borrowed from DDD — offers a better approach: each opportunity in its own bounded, auditable space, with a structured memory.

One file, a few directives, and Claude does the rest — how I structured 500 emails effortlessly

Drowning in email and losing track of the threads in flight? By handing the structuring over to Claude — one file, a few directives, then a gradual split — I turned 500 building-management emails into a queryable knowledge base. Seven steps, from the vague directive to a multi-file system, without ever needing a complex framework.
