Marketing Codebase Starter

A file structure for product marketing teams using AI. Treat your messaging like code: modular, versioned, always current.

The Idea

AI works better with many bite-sized files than one big document. This structure organizes your marketing knowledge so AI tools can pull the right context for any task.

The payoff: Update your messaging once, every AI workflow gets the latest automatically.
