## UX Writing Principles

### The 4 Cs of UX Writing
```
Clear: Easy to understand immediately
Concise: As few words as possible
Consistent: Same words for same actions
Conversational: Human, not robotic
```

### Core Guidelines
```
- Lead with the benefit
- Use the user's language
- One action per message
- Front-load important info
- Be positive when possible
- Guide, don't command
```

## Button Copy

### Button Best Practices
```
DO:
✓ Use action verbs
✓ Be specific about the outcome
✓ Match the user's goal
✓ Keep it short (1-3 words)

DON'T:
✗ Use vague words (Submit, OK)
✗ Create anxiety (Delete Everything)
✗ Be generic (Click Here)
```

### Button Examples
```
Vague → Clear

"Submit" → "Create Account"
"OK" → "Got it" / "Save Changes"
"Cancel" → "Keep Editing" / "Discard"
"Click here" → "View Pricing"
"Yes" → "Delete File"
"Next" → "Continue to Payment"
```

### Primary vs Secondary Actions
```
Primary (what you want them to do):
- Strong, clear action
- "Start Free Trial"
- "Add to Cart"

Secondary (alternative):
- Lower emphasis
- "Maybe Later"
- "Learn More"
```

## Error Messages

### Error Message Formula
```
[What happened] + [Why it happened*] + [How to fix it]

*Optional if obvious
```

### Error Message Examples
```
Bad:
"Error 404"
"Invalid input"
"Something went wrong"

Good:
"Page not found. Try searching or go to the homepage."
"Password must be at least 8 characters."
"We couldn't save your changes. Check your connection and try again."
```

### Error Tone Guide
```
- Never blame the user
- Be specific about the problem
- Provide a path forward
- Use plain language
- Be appropriately serious

Instead of: "You entered an invalid email"
Try: "Please enter a valid email address"
```

## Empty States

### Empty State Formula
```
[Acknowledge the emptiness]
+
[Explain what will appear here]
+
[Action to get started]
```

### Empty State Examples
```
No search results:
"No results for '[search term]'
Try different keywords or check your spelling."

Empty inbox:
"All caught up!
When you receive messages, they'll appear here."

No items:
"No projects yet
Create your first project to get started.
[+ Create Project]"
```

## Onboarding Copy

### Welcome Screen
```
Headline: Focus on value, not features
Subhead: What they can do/achieve
CTA: Start the journey

Example:
"Track your finances effortlessly"
"See where your money goes and save more."
[Get Started]
```

### Tooltip Copy
```
Title: What this feature does (optional)
Body: Why it's useful
Keep under 120 characters

Example:
"Keyboard shortcuts
Press Cmd+K to quickly search
anything in your workspace."
```

### Progress Steps
```
Show where they are:
"Step 2 of 4"

Show what's next:
"Next: Add your team members"

Encourage completion:
"Almost done! Just one more step."
```

## Form Copy

### Labels
```
- Be specific ("Work email" not "Email")
- Use familiar terms
- Match user's mental model
- Indicate optional fields explicitly
```

### Placeholder Text
```
DO: Provide examples
"e.g., john@company.com"

DON'T: Repeat the label
"Enter your email"
```

### Helper Text
```
When to use:
- Explain formatting requirements
- Provide examples
- Note privacy/security

Example:
"Password must include a number and special character"
```

## Confirmation Messages

### Success Messages
```
- Confirm what happened
- Suggest next steps
- Be proportionally enthusiastic

Simple: "Saved"
Standard: "Your changes have been saved."
Milestone: "Account created! Check your email to get started."
```

### Destructive Action Confirmations
```
Be clear about consequences:

Title: "Delete this project?"
Body: "This will permanently delete 'Project Name'
and all its files. This cannot be undone."

Actions: [Cancel] [Delete Project]
```

## Microcopy Patterns

### Loading States
```
Brief: "Loading..."
Informative: "Loading your dashboard..."
Progress: "Importing contacts (45 of 200)..."
Reassuring: "This may take a moment..."
```

### Notifications
```
Format: [Icon] [What happened] [Optional action]

"✓ File uploaded"
"⚠️ Connection lost. Retrying..."
"🔔 New message from Sarah [View]"
```

### CTAs Throughout UI
```
Navigation: "Back to Dashboard"
Upgrade: "Unlock Pro Features"
Help: "Need help? Chat with us"
Save: "Save and Continue"
Share: "Invite Teammates"
```

## Voice & Tone

### Tone Spectrum
```
More serious ← → More playful

Error: More serious
Success: Can be playful
Neutral: Middle ground
Empty states: Slight warmth
```

### Consistency Checklist
```
□ Same terms for same concepts
□ Same capitalization style
□ Same punctuation patterns
□ Same level of formality
□ Same voice (we/you)
```

Describe your UI element or flow, and I'll write the copy.
