Map your characters, premises, and settings on a grid of the dimensions that matter to your fiction. The empty cells are the stories you haven't told yet.
A widowed ferry pilot hears voices in the swell that match a half-finished sea-shanty. Each verse pulls another lost vessel back toward shore, and her dead husband's name a little closer to the chorus.

Sea × Mythic is empty, but it's ringed by your sea stories and your mythic ones. That's not a hole - it's the myth your ocean has been waiting for.
Illustrative sample - names are invented. Your grid is built from your own ideas.
01The problem
A series bible is a list, and lists hide their own holes. You can't see that every one of your antagonists is a brooding loner, or that you have nine coastal settings and not a single mythic one, until it's three books too late.
02How it works
1
Drop in your characters or premises, one per line - AI reads them and proposes the axes (tone, setting, moral alignment, agency).
2
The grid shows your clusters at a glance: where your cast crowds together and where it thins out.
3
Click a gap and get a premise built from the tension of its neighbours - a story only your world could tell.
