UX writing
Writing the words inside a product so people can finish the task. The wording is part of the design, not decoration added at the end.

What it is
UX writing treats interface words as a design material. The job is not sounding clever, it is moving someone from 'I want to do this' to 'done' with the fewest dead ends: labels that match what people already expect, screens that state the cost of a click before it happens, errors that hand control back.
Day to day that means naming one concept one way across the whole product, cutting words that do no work, sequencing information in the order the user needs it, and pushing back on the flow itself when the copy is apologizing for a bad screen. A UX writer handed only finished mockups is being used as a spellchecker.
Common mix-up: UX writing versus copywriting. UX writing guides someone through a product interaction; copywriting usually persuades in a marketing or sales context. The two overlap constantly, and in small teams the same person does both. The difference that bites is context, not funnel position: a marketing page can be playful about the product, and a failed payment cannot.
Ask AI for it
Act as a UX writer and rewrite the copy in this flow. For each screen give me: the screen goal in one sentence, then the revised heading, body, primary button, secondary button, and every error state. Rules: task-oriented headings, one idea per screen, button verbs that match the outcome, no term the user has not met earlier in the product, and one word per concept (list the chosen terms at the end). Flag any screen where the copy is compensating for a confusing design, and say what to change in the design instead.
