Ad Copy Writer#

Write ad copy, marketing copy, product copy, headline variants, CTA variants, and promotional messaging that are concise, persuasive, and channel-aware. Use this skill when the user wants to draft, rewrite, or polish persuasive copy for ads, landing pages, launches, or campaigns.

Prerequisites#

• WERYAI_API_KEY must be set before calling the API.
• Node.js >=18 is required because the runtime uses built-in fetch.
• Real runs use the WeryAI chat completion API and may consume credits.

Example Prompts#

• Write 5 ad copy variations for a productivity app launch.
• Turn this product brief into landing page copy with a stronger CTA.
• Rewrite this ad so it sounds less generic and more benefit-driven.
• Draft short paid social copy for a skincare product in English.

Quick Summary#

• Main jobs: ad copy writing, marketing copy, landing page copy, headline variants, cta variants, promotional rewrite
• Default model: GPT_5_4
• Main optional controls: product, brand, audience, tone, format, cta, keywords, mustInclude, avoid
• Main trust signals: dry-run support, model lookup, channel-aware preset, direct copy-ready output

Workflow#

1. Capture the product, offer, audience, channel, tone, and desired call to action.
2. If the user wants a specific ad shape such as headline set, landing page copy, CTA variants, or paid social copy, read references/domain.md and match the closest pattern.
3. Ask only for the smallest missing detail needed to write persuasive copy.
4. Use --dry-run first when you want to inspect the final payload.
5. Run node {baseDir}/scripts/write.js --json '...' and return the final copy directly.

Commands#

sh

# List available chat models
node {baseDir}/scripts/models.js

# Write ad copy
node {baseDir}/scripts/write.js --json '{
  "prompt":"Write 5 ad copy variations for a productivity app launch",
  "product":"AI productivity app",
  "audience":"busy professionals",
  "format":"paid social ad",
  "cta":"Start free trial"
}'

# Rewrite marketing copy without calling the API
node {baseDir}/scripts/write.js --json '{
  "prompt":"Rewrite this ad so it feels sharper and more benefit-driven",
  "sourceText":"...",
  "product":"skincare serum",
  "tone":"premium but clear"
}' --dry-run

Definition of Done#

• The final output reads like persuasive copy rather than a memo or explanation.
• The wording matches the requested channel, audience, and CTA closely enough to use as a draft.
• If the user asked for variations, the output clearly separates them.

When Not to Use#

• Do not use this for long-form articles or blog posts.
• Do not use this for pure translation without copy adaptation; use copy-translator instead.
• Do not use this for general brainstorming with no copy deliverable.

Re-run Behavior#

• Re-running write.js creates fresh copy variations and may consume additional credits.
• Re-running write.js --dry-run is safe and does not call the API.
• Re-running models.js is safe and only refreshes the available chat model list.
