An AI writing room for novelists
From one premise to a finished novel.
Tell it the story you want. A room of AI agents plans, writes and logic-checks the book chapter by chapter, while you watch and steer.

Loaded outline, recent chapters, active characters
The writing room, in miniature. Watch the logic editor catch a timeline slip and send it back.
Logic review
It catches its own mistakes before you read them.
Long AI drafts fall apart on details: a dead man speaks, a week becomes two days, a secret is known by someone who was never in the room. Here, a separate editor reads every chapter against the story so far and runs seven checks. Anything that fails goes back to the writer, and you see the whole exchange.

Days, seasons and ages add up from chapter to chapter.
Numbers
Nine riders stay nine riders. Distances, debts and head counts hold.
Causality
Nothing happens because of something that has not happened yet.
Who knows what
No character acts on a secret they were never told.
Evidence and objects
The letter that burned in chapter 5 is not read aloud in chapter 9.

Wounds, promises, locations and names carry forward.
Voice and audience
The prose stays in the register your readers expect.

Characters
A cast that keeps itself current.
Characters are created for you when the book is planned, then updated after every chapter: what they know, where they stand with each other, what changed and why. Chapter 30 remembers chapter 3, and you can read the whole record at any point.
