Canonscribe

Keeps track of your world, but won't write it for you.

macOS, Apple Silicon & Intel.

Reads every scene as you write it, keeping the summary, cast, and continuity current — automatically.

Canonscribe's Write tab, with chapters on the left, the manuscript editor in the center, and an AI summary plus live scene context — who's on stage, what happened previously — on the right.

What it's for

Canonscribe reads your novel as you write it and remembers what you can't.

Every scene gets tracked as you go — who knows what, where things are, how much time has passed — so continuity errors surface while you're still writing, not after your editor finds them. It's an editor's memory, not a ghostwriter.

What it does

Tracks continuity automatically Every scene is digested for characters, locations, objects, and timeline as you write — no story bible to maintain by hand.
Answers with citations Ask it anything about your book. It re-reads the actual text, cites the scene, and says "the text doesn't establish that" instead of guessing.
Runs a full analysis sweep Contradictions, timeline errors, knowledge violations, dangling threads, scenes that aren't pulling their weight.
Builds a plot grid Define your own plot threads as columns — the AI fills in what each one does, scene by scene.
Generates a living wiki Characters, locations, and storylines, built from what you've actually written — always current, never stale.
Checks series canon Writing a sequel? It checks the new book against everything already established in the last one.
Keeps your manuscript local Your book lives in storage on your own device, not locked inside a server you don't control.
