UX Writer

Overview

This skill helps you craft clear, helpful, and human UI text that guides users through your product without friction. UX writing is not marketing copy—it lives inside the product and its job is to reduce confusion, build trust, and move users toward success. Good microcopy is invisible when it works and painfully obvious when it doesn't. This skill covers the full spectrum of in-product text: button labels, error messages, empty states, tooltips, onboarding flows, confirmation dialogs, form helper text, and success messages. The output is production-ready copy, not placeholder text.

When to Use

• Writing or rewriting button labels and CTAs inside a product
• Crafting error messages that explain what went wrong and how to fix it
• Designing empty states that guide users toward their first action
• Writing onboarding flows, welcome screens, and feature tours
• Composing tooltip and helper text for complex fields or controls
• Creating confirmation dialogs, destructive-action warnings, and success messages
• Auditing and improving existing UI copy for clarity and tone consistency

When NOT to Use

• Marketing landing pages, ads, or campaign copy (use copywriter skill instead)
• Long-form help articles or user manuals (use technical-writer skill instead)
• Brand naming or tagline development
• Social media posts or email newsletters
• Legal disclaimers or compliance text (consult legal)

Quick Reference

Instructions

1. Identify the UI element and context. Determine exactly what element needs copy (button, error, tooltip, etc.), where it appears in the user journey, and who the user is at that moment. A user mid-checkout needs different language than a new signup exploring features.

2. Define the job of the text. Every piece of microcopy does exactly one job: inform, instruct, reassure, warn, or motivate. Name the job before you write a single word. Copy that tries to do two jobs usually does neither well.

3. Write in plain language. Use the simplest word that does the job. "Start" over "Initiate". "Delete" over "Remove permanently". Aim for a reading level your least technical user can parse at a glance—UI text is read in seconds, not minutes.

4. Apply the error message formula for all error states. Structure: (1) what happened in plain terms, (2) why it happened if helpful, (3) what the user can do next. Never blame the user ("You entered an invalid email") — be neutral or take system responsibility ("That email address isn't valid — check for typos and try again").

5. Shorten ruthlessly. Count your words, then cut 30%. Every word costs attention. Button labels should be 1–3 words. Tooltips: one sentence. Error messages: two sentences max. If a concept needs more than that, the UI probably needs redesign, not more copy.

6. Check consistency. Use the same verb for the same action throughout the product. If the nav says "Sign in", the button must not say "Log in". Inconsistency erodes trust faster than bad copy does.

7. Test against your voice and tone guide. If the brand is warm and conversational, "Oops, something went wrong" fits. If it's enterprise and formal, it doesn't. When in doubt, default to neutral and direct.

8. Write variants and compare. Generate 3 options for any important piece of copy, then evaluate against: clarity, brevity, brand tone, and whether it reduces or increases user anxiety.

Examples

Example 1: Error Messages for a Sign-Up Form

Input: "Write error messages for a sign-up form. Fields: email, password (min 8 chars, must include a number), username (3–20 chars, letters and numbers only). Tone: friendly, modern SaaS."

Output:

Email field errors

Password field errors

Username field errors

Success state

You're all set, [Name]! Your account is ready. Let's get started. → Go to dashboard

Example 2: Empty State for a Project Management App

Input: "Write empty state copy for a project management app. States needed: no projects, no tasks in a project, no team members. Tone: encouraging, startup-friendly."

Output:

No projects yet

Heading: Your workspace is ready. Body: Projects live here. Create your first one to start organizing work, tracking tasks, and collaborating with your team. Button: Create project

No tasks in this project

Heading: Nothing here yet — that's about to change. Body: Add your first task to kick things off. Break your project into steps and start making progress. Button: Add task

No team members

Heading: You're working solo — for now. Body: Invite your team to collaborate, assign tasks, and move faster together. Button: Invite people Secondary link: Learn how sharing works →

Example 3: Destructive Action Confirmation Dialog

Input: "Write a confirmation dialog for permanently deleting a user account. The action cannot be undone. Tone: serious but not alarming."

Output:

Dialog title

Delete your account?

Dialog body

This will permanently delete your account, all your projects, and your data. This can't be undone.

Buttons

• Primary (destructive): Delete my account
• Secondary (cancel): Keep my account

Design note: The cancel action should be the visually prominent button. The destructive action should be secondary in visual weight but clearly labeled.

Best Practices

• Lead with what the user can do, not what they can't: "Save up to 5 files" not "You can't save more than 5 files"
• Name the object in button labels: "Delete project" not "Delete" — specificity prevents accidental actions
• Use sentence case for UI text (not Title Case or ALL CAPS) unless brand standards differ
• Avoid jargon, internal terms, and engineering-speak in user-facing copy
• Write gender-neutral, inclusive copy; prefer "they" for singular unknown users
• Pair error messages visually with the field they describe — proximity beats explanation

Common Mistakes

• "Click here" links: Screen readers read links out of context; the link text must describe the destination
• Vague errors: "Something went wrong" is never acceptable without a recovery action
• Over-apologizing: "We're so sorry, but unfortunately..." wastes characters and
