One page for every character, place, faction, and chapter, in one place across every book. Eidos tells you which entries are missing a detail, draws the story on a canvas, and keeps what you decided. It never writes a word of your book.
Free for macOS, Windows, and Linux. No account, no subscription.
Sound familiar?
Seven notebooks, three apps, and one city founded in two different years.
Notes in a dozen files and three apps, each a little different, and no single place that is right.
Each book gets its own project, so the bible gets copied, and the copies quietly drift apart.
A character who could not talk in one book speaks whole sentences in the next. Small details slip while the plot has your attention.
How it fits
Start from the World framework, add chapters from the Book framework, and every part of your story gets a page with the same sections every time: why it exists, what is true, what is still to decide, and what it is not.
What you will use most
The health check lists every entry missing a section its template asks for, so an unfinished character page never hides.
Places, people, and chapters as cards that open their pages, with arrows for who rules what and what happens next.
“She survives book one.” Write it down once, mark it confirmed, and it stays linked to her page, with who settled it and when.
A co-writer or beta reader leaves a note on the exact section it is about, and you close it once it is answered.
Revisions and continuity checks on a board, each pointing at the chapter or character it is about.
Nothing happens unless you connect one and ask. If you do, it can tell you where a chapter disagrees with a character’s page, and it changes nothing until you say so.
Unfinished pages
Your home page leads with the health check: every character, place, and chapter missing a section the template asks for. It checks that entries are complete, not that the story agrees with itself; that is still your job, or your assistant’s if you ask it.
The whole story
Lay out the places, the people, and the chapters of a book, join them with labelled arrows, and leave yourself sticky notes. Every card opens its page, and its colour tells you whether it is canon yet.
Optional
If you use an AI assistant, ask it whether part two contradicts a character. It reads the pages you point it at, quotes the line that disagrees, and asks before it changes anything. It never touches your prose.
