Build the world.
Then write it.
CanonBoard is a world logic engine for screenwriters, showrunners, and writers' rooms — the only tool that actively stress-tests your canon instead of just storing it.
Free solo plan. Upgrade for teams.
Signal keeper.
"Maren died eleven years before the signal was built."
You can't write your way out of a logic problem.
The logic, rules, characters, and relationships your world runs on — built here, stress-tested here, before a word of script is written.
Here your world gets stress-tested and stored.
Your timeline doesn't add up. CanonBoard knows before the network does.
Run an AI scan across your full world and get every continuity break, with an explanation per conflict — dead-then-alive characters, broken rules, two characters in one place at one time. Available on Core and above; 1 credit per scan.
Every connection in your world, drawn. Pull one node, see what breaks.
Characters, locations, rules, lore — one navigable graph, every edge labelled. Geography pins it all to a map, real or invented. Both free, because a world you can see is a world you keep building.
It interviews you, one question at a time — and shapes your answers into canon.
"What does Eli believe about the world that isn't true?" Ten questions per session. Your answers become structured canon on the board — excavated from you, never invented for you.
Everything else your world runs on.
The work between the idea and the first draft.
Four steps. No setup. The engine is live the moment your first card lands.
World builders, not just writers.
If a single dropped detail can blow up your franchise, you need a world logic engine. Not a wiki.
Your world bible lives in five places. That's the problem.
Notion, Google Docs, a whiteboard, and two notebooks. When episode 4 changes a character, episode 7's writer finds out at the table read.

The questions every team asks.
Does the conflict engine use AI?+
Yes. Conflict Detection reads your full world on demand and surfaces every continuity break — dead-then-alive characters, broken rules, two characters in the same place at the same time — with an explanation per conflict. Available on Core and above; each scan costs 1 AI credit.
Will Refine write my script?+
Never. Refine interviews you, one question at a time, and parses your answers into structured canon cards. The page stays yours.
Can I bring in an existing bible?+
Yes — Smart Import (Core and up) reads a script, treatment, or doc and builds the board automatically. 2–3 credits depending on length.
How do team seats work?+
Core includes 3 seats, Pro 8, Studio 15 — plus $5/seat beyond that. Invite by email with view, comment, or edit roles.
Who owns my world?+
You do. Always. Export your bible at any time, revoke share links instantly, delete your account and we delete your data.
