Claude skills for writing and editing: articles, marketing copy, docs and specs, interface text and cleaning up AI-sounding prose.

ranked

writing-beats is the most installed writing skill. It turns a file of rough notes into an article one section at a time, and you choose each next section.

The others cover marketing copy, line editing, docs and specs, interface text and removing AI-sounding phrases. Skills shape how Claude writes, but they do not know your facts, so you still supply the material and read the result. For writing help without installing anything, see AI for writers. For search-focused content, see Claude SEO skills.

Good for

  • Writers and bloggers who turn notes into articles
  • Marketers who write and edit landing page copy
  • Teams that write specs, proposals and docs
  • Anyone who wants AI-sounding text rewritten in their own voice

  3. 3

    Build the article beat by beat

    It asks once where to save the article. Then it offers two or three starting beats, writes only the one you pick, and re-reads the file before each write, so your own edits are kept.

    Prompt
    writing-beats: turn notes.md into an article. My reader knows basic spreadsheets but has never used pivot tables.

    Tip: Example prompts are illustrations; use your own notes and reader.

    Uses writing-beats

  4. 4

    Remove the AI tells

    humanizer marks the tells, drafts a rewrite, checks it against 26 patterns and the original, then writes the final version. It adds no facts, so read the result before you publish.

    Prompt
    Humanize the prose in article.md. Keep my facts and my voice.

Questions

What is the best Claude skill for writing?

By installs on skills.sh, writing-beats leads, followed by copywriting and copy-editing. The right one depends on the job: writing-beats for articles, copywriting for marketing pages and doc-coauthoring for specs and proposals.

Can Claude remove AI-sounding phrases from my writing?

Yes. humanizer checks 26 patterns, such as "not X but Y" contrasts and forced triples, and rewrites them. Its README says getting past AI detectors is not a goal and that detectors still flag most of its output.

Can Claude write in my own voice?

Partly. Give humanizer two or three paragraphs of your own writing and it matches your voice. copywriting also keeps the argument and words of a draft that already has a real voice.

Can Claude edit my draft without rewriting it?

Yes. copy-editing improves copy you already have in seven sweeps, from clarity to proof, instead of rewriting it from scratch.

Can Claude help me write a spec or proposal?

Yes. doc-coauthoring is Anthropic's three-stage workflow for proposals, PRDs and design docs. technical-writing applies a stricter house style to specs, READMEs and reports.

Do writing skills make Claude invent facts?

They try to prevent it. copywriting flags missing proof as a placeholder instead of inventing it, and writing-beats builds the article from your own notes. You still need to check every claim.

What is the difference between this list and SEO skills?

This list is about writing and editing. For keyword research and search-focused content, see Claude SEO skills.

Are Claude writing skills free?

Yes. You pay only for your Claude plan or API use. The skills themselves cost nothing to install.

How do I install a writing skill?

Run the npx skills add command from the steps above with the skill's name, or use the install box on its page.
