Drafts produced or polished by a model share recognisable habits: padded openers, stock vocabulary, staged contrasts, uniform rhythm and claims that name nothing. Readers notice them and trust the text less. This skill finds those habits, rewrites them by stating the actual point plainly, and then puts the author's own voice back, without changing a single fact. It works on any text and with any agent.

When to use

  • A blog post, LinkedIn post, newsletter or page "sounds like AI" or "like every other company".
  • Before publishing a draft Maggie or another tool wrote, when the user wants it to read like them.
  • After a copy edit, as the last pass on voice.

Not for: writing from scratch (cmo-blog-writing or cmo-copywriting), checking a Maggie draft against the brief and facts and saving it (cmo-draft-review), or a full clarity and persuasion edit (cmo-copy-editing).

What is the Humanise AI writing skill?

Remove AI writing tells so text reads like a person wrote it, without losing facts.

It's one of cmo.so's open Content & copy skills: a SKILL.md file that tells an AI agent when to use it, what to ask you first, the steps to follow, the checks to pass and what to hand back, so the job is done the same careful way every time.

When should I use it?

Reach for it when you'd otherwise say something like “This sounds like AI”, “Make it sound more human”, “Deslop this”. Your agent reads the skill's description and picks it for requests like these, so you don't need to name it.

If a request is close but not quite right, the skill says so and points to the related skill that fits better, instead of forcing a poor answer.

What do I need to give it?

It works best with the text to fix (blog post, LinkedIn post, email, page copy); one sample of writing the user likes, or the brand voice notes; and audience and purpose of the piece.

You don't have to prepare everything up front. The skill asks for missing pieces one at a time and says plainly when it's working from an assumption instead of your data.

What do I get back?

You get a tell audit: each pattern found, where, and severity; the rewritten text with facts, links and structure intact; and a short change log and a list of claims that need a real source.

Every result comes from a written method with a quality bar, so numbers name their source, claims are checked and the output is ready to use or share rather than a rough draft.

Is it free?

Yes. The skill is open source under the MIT licence, so you can use it, change it and share it, including for client work.

Seeing, copying and downloading the whole file on cmo.so needs a free sign-in. Copying also upvotes and saves it, so you can find it again under Saved on the skills page.

Which AI agents can use it?

Claude Code installs it from the cmo.so marketplace. Any agent that reads SKILL.md folders, such as Codex or Cursor, can use it once the folder is in its skills directory.

You can also paste the copied skill into ChatGPT, Claude or any assistant at the start of a conversation and ask it to follow the skill.

How do I install it?

In Claude Code, run /plugin marketplace add AI-Marketing-OS-LTD/cmo-so-skills, then /plugin install cmo-so-content@cmo-so. That installs this skill together with the rest of the Content & copy group.

For other agents, sign in, press Copy or Download above and put the file in your agent's skills folder as SKILL.md inside a folder named after the skill.

Do I need a cmo.so account to use it?

No. The skill works on its own with whatever your agent can already see and do: your files, the pages you share and the data you paste in.

A free cmo.so account only matters if you also want Maggie to plan, write and publish your marketing every day.

Which skills work well with it?

It pairs well with Copy editing; and Draft review & publishing. The agent can hand over from one to the next in the same conversation, for example research first, then the plan, then the writing.

Each of them has its own page with what it needs and what it returns, linked below.

Can I change it to fit my business?

Yes. It's a plain Markdown file, so you can edit the steps, add your own checks and examples, and keep your version in your own repo. The MIT licence allows it.

If your change would help others too, suggest it on the skills page or open a pull request on GitHub, and it may be folded into the library for everyone.

Where does the method come from?

It's written by cmo.so and adapts open work by others, credited on this page: every-app/open-seo (MIT); AgriciDaniel/claude-seo (MIT); and JeffLi1993/content-repurposing-skills (no license).

Only permissively licensed work is adapted; copyleft repos are used for ideas only and repos without a licence aren't used at all.

Is my data sent to cmo.so when the agent uses it?

No. The skill only guides your own agent; your files, documents and data stay wherever your agent and its tools keep them.

cmo.so only sees what you connect to cmo.so. Your votes and saves on this page are stored against your cmo.so sign-in.
