Polish packs a lot of meaning into word endings, and much of it disappears in translation. Winston AI checks Polish text for signs of AI writing and highlights the sentences that read as machine-written. This page explains why you should scan the original, how formal address works, and what to do with a result.
Why the original matters
Polish nouns change form across seven cases, past-tense verbs mark gender (napisał, napisała), and word order is flexible because the endings carry the grammar. A writer's choices show up in all of that: which word goes first for emphasis, which form of address they pick, how they handle verb aspect. Translate the text into English and most of those choices are flattened or replaced by the translation tool's.
That's why it's worth scanning Polish in Polish. A translated version mostly tells you about the translation. If a student handed in work in Polish, the Polish file is what you should review; a translation made for a colleague who doesn't read Polish is a different document. Winston AI detects Polish automatically, so paste the text as-is, ą, ę, ł and all, then hover over or tab to any highlighted sentence to see its AI probability.

In each case, a score is a starting point. School essays such as the rozprawka follow a taught pattern (thesis, arguments, conclusion), so a tidy structure is expected. Polish academic writing has formal habits of its own (impersonal forms like 'w pracy przedstawiono', long noun phrases), and those are human conventions too. Before acting on red highlights, compare the text with the writer's earlier work and ask about drafts. Our guide on whether AI detectors can be wrong explains how to weigh a result.
