ai-copywriter

ai-copywriter is a prompt pack, not software. It's a portable agent "skill", a structured SKILL.md instruction set that teaches any capable LLM to write marketing copy using real copywriting frameworks and then strip out the tells that make text read as AI-generated. It bundles 33 specific fixes drawn from Wikipedia's "Signs of AI writing" list.

Because it's instructions rather than code, it runs anywhere an agent runs: Claude, ChatGPT, Manus, whatever you've got. It's versioned, MIT licensed, and credits the upstream humanizer work it builds on, so it's a legit community project rather than a scraped prompt dump.

For anyone using an AI assistant to draft landing pages, emails, or ads, it's a free upgrade to your output quality. Install it through the Skills CLI or as a Claude Code plugin and point your agent at it.

The catch is exactly what it is: a Markdown file. There's no app, no guarantee, and results still ride entirely on the model you run it against. Treat it as a good starting prompt you'll still edit, not a copywriter in a box.
