What is Subtxt?

Subtxt is a structured storytelling platform that analyses outlines, scripts, and drafts to map characters, plot points, and thematic throughlines. It applies a mathematically grounded framework to detect inconsistencies, measure narrative strength, and highlight areas where conflict and impact can be increased.

The tool offers dual modes—Flow for rapid ideation and Focus for logical structuring—allowing writers to switch between intuitive brainstorming and rigorous revision. Interactive “Play Mode” lets creators experience their stories as branching narratives, with real‑time thematic alignment and continuity checks.

Subtxt Muse extracts hidden subtext from raw notes, organizing it into actionable story elements. The open‑source Narrative Context Protocol™ enables consistent intent across multi‑agent systems for film, games, and AI‑generated content. Screenwriters, novelists, game designers, directors, producers, and studio executives can use Subtxt to ensure coherent plotlines, balanced character arcs, and clear thematic focus throughout development.
