PlotKit
Story Engineering Tool — Free to start

Design your novel the way
an architect designs a building

Structure-first planning for fiction writers who think in systems. Visual plot graphs, character networks, hierarchical outlines, and a consistency audit that catches what your spreadsheet misses.

Everything a plotter needs

Built for writers who plan before they write.

Foundation

Story Codex

Structured records for every character, location, world rule, faction, and key object. Your single source of truth — no more hunting through scattered notes.

Visual

Plot Graph

A visual network of every plot event and how they connect. See causes, consequences, and subplots at a glance. Export as PNG to share or print.

Visual

Character Relationship Network

Map relationships between every character in your story. Track how alliances, rivalries, and romances evolve chapter by chapter.

Smart

Consistency Audit

AI-powered analysis that catches codex contradictions, timeline breaks, and unresolved subplots before they become publishing problems.

“Design your novel the way a software architect designs a system — with a schema, enforced rules, and consistency checks at every layer.”
