SMAG is an AI-driven multi-agent system designed to automate key stages of scriptwriting. It leverages distinct agents: a Plot Agent for generating story skeletons, a Character Agent for building profiles and motivations, a Dialogue Agent to craft natural, genre-specific conversations, and a Scene Agent to structure scene-by-scene breakdowns. Users input high-level parameters such as genre, tone, and character archetypes, then SMAG iterates proposals across agents to ensure narrative coherence. The platform supports real-time collaborative edits, version tracking, and customizable prompt templates. With integrated export options (PDF, Final Draft), SMAG fits seamlessly into writers' existing workflows, accelerating ideation and reducing manual drafting time.
