Copywriting Skill
Principles-based copywriting skills with a human-voice layer
About
A free copywriting library by Jules Sauvajol built on direct-response fundamentals (Drayton Bird, Eddie Shleyner, Hopkins, Ogilvy) rather than templates — teaching the agent what to look for before it writes. It ships six skills (web copy, SEO copywriting, French copywriting, social for LinkedIn/X, tone-of-voice, career copy) with a human-voice editing layer aimed at removing AI tells, a critique-before-rewrite workflow, and worked examples. The strength is the principles-first approach plus native French copy, which is rare in skill packs. The limitation: a 3-star audience means limited vetting, and the quality claims rest on the author's method, not measured results.
What it can do
- copywriting: web, landing page, email, CTA, value proposition
- seo-copywriting: briefs, pillar pages, metadata, refresh planning
- french-copywriting: native French rhythm, tu/vous, typography
- social-copywriting: LinkedIn and X posts, threads, carousels
- tone-of-voice: reusable brand voice guides
- career-copywriting: CVs, cover letters, LinkedIn profiles
- critique-before-rewrite workflow
- human-voice-rules reference for AI-tell removal
