What it is

CrackArc brings drafts, characters, places, timelines, facts and sources into one connected project.

Every revision is kept, projects stay in portable folders on your computer, and optional local AI can suggest changes without editing approved material on its own.

What it does

Everything CrackArc can do.

17 features as of version 1.3.1, grouped by what you want to do. What changed lately →

Writing

Projects that stay yoursEach world is an ordinary folder on your PC; nothing goes online.
Full writing historyAutosaved drafts plus revisions you commit (Ctrl + S) that are never overwritten.
Recovers after a crashReopen the project and your unsaved draft is there.

Canon

CodexCharacters, places, organisations and events with aliases and small, checked facts.
Facts and claims kept apartWhat is true in your world is never mixed up with what someone in it says.
Exact citationsA fact can point to the exact passage that supports it, and opens it highlighted.
Retraction, not deletionRetracting shows the impact first and can always be undone.
DependenciesRecord that one fact needs another; loops are flagged for you.

Checking and finding

ContinuityChecks dates, ages, locations, lost sources and broken dependencies, and names the exact facts involved.
SearchEverything you wrote, every name, alias, fact and claim, with filters.
World viewsA relationship graph, a year-by-year timeline and a hierarchy, from what you actually recorded.

Sharing and safety

ExportsMarkdown for reading or an AI chat, or JSON, with confirmed facts, disputes and claims clearly separated.
Backups and portable copiesVerified backups and independent copies you can move to another PC.

Optional local AI

Suggestions that wait for youA local model can suggest characters, facts and claims; nothing enters your canon until you approve it.
Off by defaultEverything works without a model; downloads show their source, size and licence first.
