Claude Prompts for Content Creation: 12 for Posts and Emails
12 Claude prompts for content creation: build a voice guide from your writing, outline from notes, draft newsletters, check claims, and set up a Project.

Claude prompts for content creation work best when you give Claude your own writing first: paste two or three pieces you have published, then your rough notes, and ask for a draft that matches your voice and uses only facts you can back up. Claude can build a voice guide from your samples, suggest angles, outline, draft, and check every claim before you hit publish. Below are 12 copy-paste prompts grouped by step, plus a flagship prompt that turns one set of notes into a finished draft in your voice.
Two limits are worth knowing. Claude only knows what you paste or upload, so any fact, number, or story it adds without your notes should be cut or checked. And if you were paid, got a free product, or sell what you feature, disclose it clearly in the piece itself, as the FTC Endorsement Guides require.

Prompts for checks and reuse

Write one piece from start to finish
The Claude Content Creation Prompt: Notes to Draft in Your Voice combines prompts 1, 4, 5, 7, 10, 11, and 12. You paste your writing samples, rough notes, audience, format and length, the facts you can back up, and your no-go list. It returns a voice guide quoted from your samples, three angles, an outline, a full draft, a claim check, headline options, and a project instructions block. The example turns a home cook's notes about one Sunday pot of black beans into a 250-word newsletter issue, and the claim check flags the one line that was not in the notes.
To reuse your voice every week, create a Claude Project, add your writing samples to the project knowledge, and paste the rules from prompt 12 into the project instructions. Projects are available on free Claude accounts, which can create up to five.
