Copy that doesn’t lose anything crossing the border.
Why Włocławek
Sierra Copywriting is based in Włocławek, Poland — not a copywriting capital, and that’s rather the point. The businesses we write for aren’t chasing a trend either: they’re exporting, entering a new market, or building something that has to work in more than one language. A Polish town on the Vistula, writing for buyers in London, Warsaw, and everywhere in between, is exactly the kind of cross-border, unglamorous work this agency exists to do.
How we write in two languages
English and Polish copy on this site — and on every project we take on — are two independent drafts from one brief, never a translation pass. That’s slower than running a source draft through a translator, and it’s the only way the second language doesn’t read as the second language. We hold ourselves to the same standard on our own site as on yours.
Standards & commitments
Every package states its scope, its revisions, and its turnaround before you pay. We’d rather say no to a project that doesn’t fit than pad a scope to make it fit. If a brief calls for AI-assisted drafting as a lower-cost option, we say so plainly — see our AI-use policy below.
Written independently, not translated
Same brief. Two original drafts.
EN
We don’t translate our own site, and we don’t translate yours. Every English sentence here was drafted by someone thinking in English, against the same brief that produced the Polish version beside it — not from it.
PL
Nie tłumaczymy własnej strony i nie tłumaczymy Twojej. Każde polskie zdanie tutaj powstało z myślą po polsku, z tego samego briefu, który — równolegle, nie na jego podstawie — dał wersję angielską widoczną obok.
Confidentiality — Your brief and drafts stay between us. Nothing becomes a case study without asking first.
AI-use policy — We use AI tools the way a careful writer uses a thesaurus or a grammar checker — for research speed and technical checks, never to draft in our place. Every sentence you receive is written and revised by a person, in the language it’s written for. If a brief specifically calls for AI-assisted drafting as a lower-cost option, we’ll say so plainly before you buy — never ship it disguised as bespoke work.
Rights — Full rights transfer to you the moment your final payment clears.
