Every word in an application matters. Well-written copy guides, engages and converts. Bad copy confuses and frustrates. This guide presents principles of UX writing and how to create texts that improve the user experience.
What is UX Writing

Buttons, labels, error messages, onboarding, notifications, tooltips, empty states.
Why Copy Matters

Clear text reduces errors and increases efficiency.
Conversion
Well-written CTAs convert more.
Support
Good copy reduces doubts and tickets.

Consistent tone of voice builds identity.
UX Writing Principles
Clarity
User understands on first reading. No ambiguity.
Concise
Fewer words, same message. Respect time.
Utility
It helps the user to do something. It's not decoration.
Consistency
Same terms for same concepts. Always.
Accessibility
Simple, inclusive, understandable language.
Tone of Voice
What is it
Personality expressed in texts. Formal, casual, technical, friendly.
Setting Tone
Align with brand and audience. Document in style guide.
Examples
"Something went wrong" (casual) vs "Processing error" (technical).
Consistency
Same tone throughout the experience.
##Microcopy
Definition
Small functional texts. Labels, placeholders, tooltips, messages.
Importance
Details make a difference. "Login" vs "Sign in to your account".
Attention to Details
Every string deserves care.
Buttons and CTAs
Clear Action
What happens when you click? "Save changes", not just "OK".
Active Verbs
"Create account" instead of "Account creation".
Visual Priority
Highlighted primary CTA. Less prominent secondary.
Examples
- Weak: "Submit"
- Better: "Send message"
- Strong: "Schedule a free consultation"
Error Messages
Be Human
"Oops, something went wrong" is better than "Error 500".
Explain the Problem
What happened, in simple language.
Offer Solution
What can the user do to resolve it?
Avoid Blaming
"The password is incorrect" instead of "You entered the wrong password."
Examples
- Bad: "Invalid input"
- Better: "Invalid email. Check format."
- Great: "Hmm, that email doesn't look right. Example: name@email.com"
Onboarding
Welcome
Warm, brief, sets expectations.
Instructions
Clear, step-by-step, actionable.
Value
Why continue? What do you gain?
Progression
Motivating feeling of advancement.
Empty States
Opportunity
Empty state is not an error. It's canvas.
Guide Action
What to do to fill it out? Clear CTA.
Example
"No projects yet. Create your first project to get started."
Notifications
Relevance
Only notify when it matters.
Clarity
Message understood instantly.
Actionability
What to do with this information?
Brevity
Limited space. Every word counts.
Forms
Clear Labels
What to fill in each field.
Placeholders
Example or tip. Does not replace label.
Validation
Specific messages by type of error.
Optional Fields
State clearly. "(optional)" works.
Loading and Feedback
Während Loading
"Loading..." is minimal. Add context when relevant.
Success
Confirm action. "Safe!" "Sent successfully."
Progress
"2 out of 5" where applicable.
Internationalization
Flexible Space
German texts are longer. Plan.
Cultural Context
Expressions may not make sense in other cultures.
Process
