Hi. I’m Jan Sinstadt.

I’m a copywriter, copy editor/proofreader and German-to-English translator. Having earlier been an electronics, electromechanical and software engineer, it’s clear that clients ask me to do a fair amount of work in hard-core science and technology. But I feel equally at home with high-gloss publications and the softer side of business, as my portfolio shows. Oh, and don’t let my Germanic-sounding name mislead you: a quarter-century after blending in with Switzerland and the Swiss, I remain thoroughly British below the surface!

Learn about what I do

I produce rocking good English text.

Readable and speakable words, crafted to resonate with specialist or general audiences and instil your meaning.


Headlines, captions, slogans, newsletters, articles, brochures, presentations, websites and more: you brief me on the key points and relevant background, then I will find the words that present them to best advantage for your intended audience.

Editing & proofreading

Text polishing and rewording. Consistent vocabulary and terminology. One voice for multiple contributors. I frame the work at hand in its surrounding context, compare and fact-check, follow reasoning, and offer tactful critique and suggestions as need be.


I work both on and between the lines, with rigour, deep understanding, and sensitivity to nuance. My renderings feel like originals. And like my other work, they flow with a rhythm and cadence designed to keep your audience reading, listening or viewing attentively to the end.
