UX writing

UX writing is the discipline that designs the text of a digital interface: button labels, error messages, confirmation text, form guidance, notifications, empty state text. Its aim is that every word helps the user understand what they can do, what is happening and what they should do next. UX writing is a component of experience design, not of marketing or communication.

Copywriting aims to convince and to engage: it is concerned with emotion, desire and persuasion. UX writing aims to clarify and to guide: it is concerned with understanding, with reducing friction and with trust. A good marketing text can be a bad interface text (too long, too vague, not actionable enough). The two disciplines can coexist within the same product, in different places and with different aims.

A good error message tells you what happened, why and how to fix it. Avoid technical jargon (« Error 500 » or « Connection refused »), guilt-inducing wording (« You forgot to fill in this field ») and negative messages with no way out. It is better to state precisely what is missing, suggest the fix, and keep a human tone. « Enter a valid email, for example name@domain.com » is better than « Incorrect email format ».

From the design stage. Text influences the layout (a long label shifts the other elements), the interaction logic (a poorly labelled button generates accidental clicks) and trust (vague text on a payment page increases abandonment). Involving the UX writer in the wireframing and prototyping phases, on the same footing as the designer, produces better results than a review at the end of the project.

A content design system is the editorial counterpart of a design system. It documents the brand's voice and tone in the interface, the phrasings to use and to avoid, the writing rules for each type of text (errors, confirmations, onboarding, empty states) and a glossary of the product's official terms. It guarantees editorial consistency across the whole product, even when several writers or teams contribute.
