In two years everyone will write with AI, and “carefully checked” will not be a claim worth making. What stays scarce is the signature: someone who says the work is his, and the mistakes too. This page is that signature, in public.
Gathering, checking reachability, first passes over documents and data. Every source that carries a claim gets read by me before the claim ships.
Outlines, first versions, rewrites for rhythm. The first version is often machine. The last version never is.
English and Dutch twins of essays and site copy. Rewritten as natives, then read as natives, by me.
Visuals in the house style, document builds, the code of this site. The standard applies to all of it: this site was built with AI, under this page.
What I recommend, what I decline, what a scheme should do. The instrument is never the judgment.
Every number, name and date in my work is verified by me or marked as unverified. An unchecked number does not ship.
Commitments, fees, timelines. Nothing binds you or me unless I wrote it, read it and meant it.
Anything concerning your project, your organisation or you personally is mine: read in full, weighed in full, signed.
Every text you receive from me was read by me before it reached you. Not skimmed: read the way I would read yours. If something in it is wrong, the standard tells you whose fault that is. Mine. That is the point of a signature.
This page will change as the tools change. The version number below moves; the last line never does.
