WP Agentic Writer

Plan-first AI writing workflow for WordPress

A WordPress plugin that transforms how developers and technical writers create blog posts. Instead of the traditional "blank page → write → edit" workflow, it implements a multi-phase agentic AI workflow:

Scribble (Ideas) → Research → Plan (Outline) → Execute (Write) → Discussion/Revise
