Righter
A UX writing skill. Review existing UI copy against a defined set of principles, or write new copy from scratch applying those principles from the start.

Two Modes
Mode 1: Review Existing Copy
For each piece of content:
- Check against the review checklist below
- Identify every violation
- Rewrite it
- Output in the review format below
Mode 2: Write New Copy
- Apply all relevant principles
- For labels, CTAs, and microcopy: read
references/phonaesthetics.mdand apply sound guidance - Output in the new copy format below
Output Formats
Review format
Use this block for every piece of copy reviewed:
Before: [original copy] After: [rewritten copy]
Principles applied:
- [Principle name]: [one sentence on why this improved the copy]
Weakeners removed:
- "[word or phrase]" → removed because [category, e.g. hedging / filler adverb / weak verb]. If none found, write "None found."
Phonaesthetics:
- Note any sound improvements made (rhythm, stress pattern, sound cluster choices, ease of mouth). If phonaesthetics wasn't a factor (e.g. error messages), write "Not applicable for this copy type."
Reading metrics (Before → After):
- Word count: X → Y
- ARI score: X.X → Y.Y
- Grade level: Grade X (age X–X) → Grade X (age X–X)
- Target: ARI ≤ 6 (Grade 5, age 10–11)
New copy format
Copy: [final copy]
Principles applied:
- [Principle name]: [one sentence on why]
Weakeners avoided:
- Note any weakener patterns consciously avoided, or write "None present."
Phonaesthetics:
- Explain the sound choices made — rhythm, stress, clusters, ease of mouth. If not applicable, say so.
Reading metrics:
- Word count: X
- ARI score: X.X
- Grade level: Grade X (age X–X)
- Target: ARI ≤ 6 (Grade 5, age 10–11)
UX Writing Principles
Apply all of these when reviewing or writing.
1. Use active voice
Subject → verb → object. Active voice is shorter and easier to follow.
- ✗ "Rewards can be earned by clicking here."
- ✓ "Click here to start earning rewards."
2. Write at or below a fifth grade reading level
Short sentences. Simple words. Clear structure. Target ARI ≤ 6.
- ✗ "If you have forgotten your password, please click on the 'Forgot Password' link and submit your registered email address."
- ✓ "Click 'Forgot Password'. Enter your email. Check your inbox for a reset link."
3. Avoid jargon
Replace technical terms with plain language. Don't assume domain knowledge.
- ✗ "Authenticate your credentials."
- ✓ "Log in with your username and password."
4. Avoid complex sentence structures
One idea per sentence. Avoid dependent clauses stacked on independent clauses.
- ✗ "The fox, which was red, over the gate jumped."
- ✓ "The red fox jumped over the gate."
5. Avoid double negatives
Double negatives increase misreads and cognitive load.
- ✗ "Please don't fail to save your changes."
- ✓ "Please save your changes."
6. Use contractions
Contractions sound human. Formal constructions feel stiff.
- ✗ "Do not submit the form until all fields are complete."
- ✓ "Don't submit until all fields are complete."
7. Write in present tense
Describe what's happening now or what the user can do.
- ✗ "Your file was uploaded."
- ✓ "Your file is uploading."
8. Frame around the user's goals, not the system
Users care about what they're doing, not how the system works.
- ✗ "Due to an HTTPS network security issue, some features are not available."
- ✓ "This site may be insecure. Some features aren't available."
9. Avoid describing the interface
Don't reference UI elements like "tab," "panel," "menu," "page," or "section."
- ✗ "Go to the Settings panel."
- ✓ "Go to Settings."
10. Use consistent terminology
Pick one word for each concept and stick to it.
- ✗ Using "Sign Up," "Register," and "Create Account" interchangeably
- ✓ Always "Sign up"
11. Apply progressive disclosure
Lead with what the user needs now. Offer detail only when needed.
- ✗ "Your password must be at least 8 characters, contain a number, a symbol, and a capital letter."
- ✓ "Your password must be at least 8 characters." [+ optional detail link]
12. Don't apologize unnecessarily
Reserve "sorry" for serious errors. Hollow apologies undermine trust.
- ✗ "Whoops! We can't upload your picture. Try again."
- ✓ "We couldn't upload your picture. Try again."
13. Limit exclamation marks
Use words to convey energy, not punctuation. One per screen max, only for genuine celebration.
- ✓ "Your profile has been updated!" (success state)
- ✗ "Error! You can't submit the form! Please fix the errors!"
14. Check prepositions
Prepositions sit between two nouns. Never start or end a sentence with one.
- ✗ "Click on the Submit button."
- ✓ "Click Submit."
15. Eliminate weakeners
Remove all hedging words, softeners, empty intensifiers, filler adverbs, throat-clearing, passive-aggressive politeness, vague quantifiers, redundant framing, weak verb phrases, and meta-commentary.
Read
references/weakeners.mdfor the full word lists and examples.
Key patterns to catch immediately:
- Hedging: maybe, probably, might be, appears to, seems like
- Filler: actually, basically, literally, just, simply
- Weak verbs: "make a decision" → decide, "conduct an analysis" → analyze
- Throat-clearing: "I think," "we believe," "it is important to note that"
Error Message Guidelines
Apply these on top of the general principles when reviewing or writing error messages.
Structure
Every error must answer:
- What happened? (required)
- Why? (only if it genuinely helps)
- What should they do next? (required)
Voice and tone
- Instructive — describe the issue precisely, optimize for understanding
- Reassuring — no disparaging tone, no unnecessary humor
- Supportive — always provide a clear next step
Mechanics
- Sentence case: "This field is required." not "This Field Is Required."
- No ALL CAPS (except real acronyms)
- 1–2 sentences max
Don't blame the user
Describe the situation, not the mistake.
- ✗ "You didn't enter enough characters."
- ✓ "This field needs 8 characters."
Form field vs system errors
- Form field — what's wrong and how to fix it: "Enter a valid email address."
- System error — what happened and what to try next: "We couldn't connect. Check your internet or try again."
Other rules
- Preserve user input where possible — let users edit rather than start over
- Place errors adjacent to the element that triggered them (Law of Proximity)
Component decision tree
Use this before writing any error message to pick the right component. Then read references/components.md for full writing rules for that component.
Does it block progress and require immediate action?
└─ Yes → Alert Dialog
Is it a system-level issue (outage, permissions, account)?
└─ Yes → Alert Banner
Is it confirming something that just happened?
└─ Yes → Toast
Is it attached to a specific form field?
└─ Yes → Helper Text
Is it contextual to a page section, non-blocking?
└─ Yes → Inline Alert
Is it a hover label for an icon or interactive element?
└─ Yes → Tooltip
Phonaesthetics
When writing new copy — especially labels, CTAs, empty states, and microcopy — consider sound alongside meaning. Copy that sounds good is easier to remember and more pleasant to use.
Read
references/phonaesthetics.mdfor the full concept guide and sound cluster table.
Core rules to apply immediately:
- Prefer consonant-vowel alternation (CVCV) for labels — natural rhythm, easy to say
- Two-beat phrases are catchy; three-beat phrases are melodic; irregular stress is awkward
- Liquids and nasals (l, m, n, r, w, y) → calm, gentle contexts
- Plosives (p, b, t, d, k, g) → energetic, action-oriented CTAs
- Avoid tongue twisters — if it's hard to say, it's hard to remember
Sound clusters to reach for:
gl-→ clarity, light (insight, vision, illumination features)fl-→ flow, ease (smooth UX, motion)sp-→ speed, energy (action, innovation)cl-→ precision, closure (tools, interactions)
Reading Metrics
Calculate and show these for all reviewed and written copy.
ARI Formula
ARI = 4.71 × (characters ÷ words) + 0.5 × (words ÷ sentences) − 21.43
- Characters = letters and numbers only (no spaces or punctuation)
- Words = space-separated tokens
- Sentences = units ending in
.?or!
Round to one decimal place. Always include grade and age range.
Grade Level Table
| ARI | Grade | Age |
|---|---|---|
| 1 | Kindergarten | 5–6 |
| 2 | Grade 1 | 6–7 |
| 3 | Grade 2 | 7–8 |
| 4 | Grade 3 | 8–9 |
| 5 | Grade 4 | 9–10 |
| 6 | Grade 5 | 10–11 |
| 7 | Grade 6 | 11–12 |
| 8 | Grade 7 | 12–13 |
| 9 | Grade 8 | 13–14 |
| 10 | Grade 9 | 14–15 |
| 11 | Grade 10 | 15–16 |
| 12 | Grade 11 | 16–17 |
| 13 | Grade 12 | 17–18 |
| 14+ | Professional | 18+ |
Target: ARI ≤ 6 (Grade 5, age 10–11)
