World expression platform
A browser editor for novel-length work. Your world stays in structured memory. Guardian flags what contradicts your canon, with the quotes. It does not write the book for you.
In a 2026 benchmark cited on our site, structured checks caught 55% of planted continuity errors. Expert readers caught 17.1%.

Remembers Your World
No setup wizard. Drop into prose — Plan, World, and Guardian come to you, not the other way around.
Open a chapter and start typing. Press / when you want a hand, right at your cursor, ⌘K for everything else. No worldbuilding gate, no blank-page ceremony.
When structure helps, step into Plan — scenes, a chapter board, a beat sheet, a timeline. The same book seen a different way. Always optional.
Characters, places, and relationships surface from your prose into World — maps, relationship webs, and cards build themselves. You tag nothing.
While you write, Guardian reads five layers — continuity, prose, scene, suspense, and plot — and flags what drifts, each with the evidence behind it.
Every flag comes with a one-click suggested fix. Apply it, open it in chat, or wave it off. Other tools generate; this one notices, and you decide.
What happens if you don't write it down?
Characters lose their names.
Histories contradict themselves.
The world you loved three months ago is already gone.
This is how worlds die unborn.
A place.
A rule.
A character you don't fully understand yet.
