Build worlds that
hold together.
Chronicle Builder is the worldbuilding and manuscript workspace for fantasy novelists — link every character, faction and place into one living codex, and write your book on top of it.
FEATURES
Everything the long form demands
A living codex, not a folder of docs
19+ entity types — characters, locations, factions, items, magic, cultures — plus your own custom kinds, cross-linked into one world your book can read from.
Worlds that share their canon
Every project lives inside a world. Two books set in the same world draw from one shared codex of characters, places and lore — so canon stays consistent across the whole series.
Every thread, connected
Tag a character in a scene and the codex is already there. A live relationship graph shows how your cast, factions and places actually connect.
Characters that hold across a series
Portraits, psychology, arcs and shared canon across every book — update once, the whole series stays consistent.
Maps that measure the distance
Upload a map, drop pins linked to your locations, and draw routes with terrain-aware travel times. The Travel Calculator estimates the journey in days and hours, and checks it against your timeline.
Calendars built for your world
Invent a calendar with months of any length, a week you define, and named holy days and festivals. Timeline events can carry dates in your own calendar — not just the real-world one.
A Name Forge grounded in your canon
Generate names, terms and place names drawn from your existing characters, locations and lore — procedurally with no AI, or with an optional AI mode for more inventive suggestions.
Your world, at a glance
The Dashboard surfaces your next timeline events, a read-only map preview with your pins, and your most recently updated notes — one look and you know where the story stands.
A real writing surface
Distraction-free editor with typewriter scrolling, set in Merriweather. Acts, chapters, scenes and beats sit alongside the prose.
Structure you can see
Plot, arcs, theme, POV balance and a tension graph that show the shape of your book — plus a continuity tracker that catches contradictions before readers do.
Bring your own AI key
Connect your own OpenAI, Anthropic, Google, xAI or OpenRouter key. Keys are encrypted at rest, route through your provider's limits, and never consume Chronicle credits.
Optional AI, when you want it
A grounded assistant for brainstorming and continuity — completely optional, off by default if you say so, and never trained on your work.
AI is opt-in, can be switched off entirely, and is never trained on your work. Read our AI policy →
WHO IT'S FOR
Built for the writers keeping a lot in their head
The epic fantasy novelist
You are three books deep and your magic system contradicts itself. Every location, every rule, every character oath needs a home that talks back to the manuscript instead of rotting in a folder of Word docs.
The series writer
Book two forgets what book one already answered. Chronicle Builder keeps a shared canon across every book in the series, snapshots the draft as it changes, and flags the contradictions before your readers catch them.
The plot-first drafter
You outline in beats before you write a scene. Arcs, subplots, tension per chapter and POV balance sit next to the manuscript — so the structure of the book is a thing you can see, not a thing you hope is working.
WHY NOT JUST USE…
A fair question. Here's the honest answer.
You could use
A word processor
Great for the sentence, blind to the story. Your manuscript lives in one file, your notes in another, and continuity lives in your head — until it doesn't.
You could use
A wiki or notes app
Endlessly organizable, disconnected from the draft. A beautiful world bible that never quite makes it into the book, and never notices when the book drifts away from it.
Instead
Chronicle Builder
Manuscript, world bible and story structure cross-linked in one studio. Write a scene, tag a character, and the bible is already there. Change a fact, and the book notices.
