Edit out the AI feel

Edits your copy with a seven-pass check and picks out phrasing that screams "AI wrote this."

Good for: People who've written an intro or announcement and want it to sound more natural

What you can do once it's installed

Just say the “You say to AI” line, with your own details swapped in.

Edit a small shop's intro

You say to AI

Can you edit this intro for my handmade shop? It reads way too much like AI wrote it.

What AI does

  1. 1.Checks clarity, tone and specifics, one pass at a time
  2. 2.Spots AI patterns like "It's not X, it's Y"
  3. 3.Marks spots that need facts for you to fill in instead of making them up

What you get

An edited intro, with the reason for every change.

Tighten an announcement

You say to AI

This announcement for my new class is way too wordy. Help me trim it down without changing what it says.

What AI does

  1. 1.Goes sentence by sentence, asking whether readers would care
  2. 2.Cuts filler and stock phrases
  3. 3.Keeps the original facts and tone

What you get

A shorter, more specific version of the announcement.

How to install

Which AI tool do you use?

  1. 1. Open the Terminal app on your computer, paste the line below and press Enter

    npx skills add coreyhaines31/marketingskills@copy-editing -g

    With no tool name, the command looks for the AI tools on your computer and asks where to install. If it says npx is missing or too old, install the latest Node.js (22 or newer) first.

    First time using the terminal?
    • How to open it: on a Mac, press ⌘ + Space and search “Terminal”. On Windows, search “PowerShell” in the Start menu. In Cursor, Trae or VS Code, use the menu Terminal → New Terminal.
    • Windows says “running scripts is disabled”: change npx at the start of the command to npx.cmd and try again.
    • If a list pops up: move with the arrow keys, press Space to tick the tools you want, then press Enter.
    • How to tell it worked: you'll see a success message. Reopen your AI tool and ask “What Skills do you have now?” to check.

    Don't feel like opening a terminal?

    Tools like Claude Code, Codex, Cursor and Trae can run commands themselves. Send them this:

    Please run this command in my terminal and tell me how it went: npx skills add coreyhaines31/marketingskills@copy-editing -g

  2. 2. Reopen your AI tool

    New Skills only get picked up after a restart.

  3. 3. Just say what you want

    Say it the way the examples do. To call it by name, say “Use copy-editing to help me…”.
