marketspec

MarketSpec is a CLI tool designed for marketing teams to create consistent, on-brand marketing materials using AI assistants. It centralizes brand foundations—voice, messaging, audience profiles, and guidelines—then uses those specs to generate context-rich prompts and validate AI-generated content. The tool organizes work by campaign, provides pre-built templates for emails, landing pages, social posts, blog articles, and more, and integrates directly with Claude Code via slash commands. Teams can generate content variations, apply feedback, and validate materials against brand guidelines in a single workflow.

Install with Node.js >= 20.19.0, then run `marketspec init` to create your project structure. Set up your brand foundation by editing voice, messaging, audience, and guidelines documents. Create campaigns and specs using the CLI, then generate AI prompts with `marketspec generate`. Validate content against your brand with `marketspec validate` before publishing.
