How to Use Claude as a UX Writer: The David Skill Guide

Nobody reads a button label and thinks “great copywriting” — they just know whether they understood what would happen when they tapped it. That is UX writing: the microcopy that makes a product feel obvious instead of confusing, written so well it disappears. Using Claude as a UX writer means getting help with exactly these small, high-stakes words — buttons, errors, empty states, onboarding hints — from a tool like Claude, ChatGPT, or any AI chat that understands the difference between writing about a product and writing inside one.

The job is best understood through the small moments it owns.

The button that tells the truth

“Submit” tells the user nothing; “Send invite” tells them exactly what happens. The skill helps you write labels that describe the outcome, not the mechanic — so a user always knows what a tap will do before they make it. Get the verbs right and half the confusion in an interface vanishes.

The error message that helps instead of blames

Most error copy is hostile or useless — “Something went wrong”, or a code number. The skill rewrites errors to do three things: say plainly what happened, why, and what the user can do next, without blaming them. A good error turns a dead end into a next step, and it is one of the highest-impact things UX copy fixes.

The empty state that points the way

A blank screen is a missed moment. The first time a user sees an empty inbox or dashboard, the skill helps you write copy that explains what goes here and nudges the first action — turning “nothing yet” into “here’s how to start.” Empty states are where good products quietly onboard.

Onboarding that respects attention

People skim; UX writing has to earn every word. The skill helps you cut onboarding and tooltip copy to the fewest words that still teach — one idea per step, no marketing voice, no walls of text. Brevity here is not a style choice; it is whether anyone reads it at all.

One voice across a thousand strings

Interfaces fall apart when every screen sounds different — formal here, jokey there, inconsistent terms for the same thing. The skill helps you set and hold a microcopy voice and a consistent vocabulary across the whole product. This is the product-side cousin of the brand work in our brand voice guide, and it shares the discipline of conversion copywriting — clarity that moves people to act.

Why a skill beats a one-off prompt

UX writing is hundreds of tiny decisions that must stay consistent. A loaded skill holds your voice, your terminology, and your patterns, so the dialog you write today matches the one from last month instead of drifting. Consistency is most of what makes microcopy feel professional.

The honest limit

The skill writes strong candidate copy from what you describe; it does not see your actual interface or watch real users struggle with it. Treat its lines as a sharp first draft to test in context — the real screen, real users, real flows decide. Used as the writer for the words too small to fuss over but too important to get wrong, using Claude as a UX writer makes a product feel like someone thought about you.
